| 41 | ----------------------------------
|
|---|
| 42 |
|
|---|
| 43 | - G4Transportation & G4CoupledTransportation:

|
|---|
| 77 | ---------------------------------
|
|---|
| 78 | - G4Transportation:
|
|---|
| 79 | o Created new method (and class member) for flag on Short StepOptimisation.
|
|---|
| 80 | * When it is true, the optimisation is 'on' steps shorter than the
|
|---|
| 81 | safety will not call G4Navigator - so long as the particle goes straight
|
|---|
| 82 | ie it is not charged or there is no field.
|
|---|
| 83 | * Retained the default value as 'off' - as since changed in
|
|---|
| 84 | transport-V09-00-02 following Alex's suggestion.

|---|
| 88 | - G4Transportation (AlongStepGPIL):
|
|---|
| 89 | o Moved the call to ConfigureForTrack before the check whether
|
|---|
| 90 | fieldMgr has 0 field ptr, in order to enable it to be called
|
|---|
| 91 | even if the field manager points to a zero field.
|
|---|
| 92 | Needed to enable a user to switch a global field on (off was possible),
|
|---|
| 93 | as a track goes between volume (or regions) of a setup.
|
|---|
| 94 | [ Response to request of Atlas/ZM. ]
|
|---|
| 95 | Note: this ordering already existed in G4CoupledTransportation.

| 99 | - G4CoupledTransportation:
|
|---|
| 100 | o Improves condition for flag that regulates Relocating when only
|
|---|
| 101 | any geometry (including a parallel geometry) limits the step.
|
|---|
| 102 | New PathFinder method required.
|
|---|

|
|---|
| 109 | geometry limited the step.
|
|---|
| 110 | o Change of condition for recalculation safety (from Alex Howard) used,
|
|---|
| 111 | as currently it improves stability.
|
|---|
| 112 |
|
|---|
| 113 | September 25th, 2007, J.Apostolakis transport-V09-00-01
|
|---|
| 114 | -----------------------------------
|
|---|
| 115 | - G4Transportation:
|
|---|
| 116 | Modification to disable 'optimisation' in G4Navigator for small linear
|
|---|
| 117 | step (ie when a track does less than the safety).
|
|---|
| 118 | * Relevant only if there is no field, or the particle is neutral
|
|---|
| 119 | * Temporary measure (in current form) to improve comparison
|
|---|
| 120 | old / new Transportation (single/old vs coupled with pathfinder).

|
|---|
| 166 | - G4CoupledTransportation:
|
|---|
| 167 | o Corrected treatment of time integration (made flags do as in original
|
|---|
| 168 | Transport).
|
|---|

|
|---|
| 176 | o G4Transportation is now the original (what was called G4Transportation8
|
|---|
| 177 | since "transport-V08-03-03").
|
|---|
| 178 | o G4Transportation8 still exists, to enable code that utilises it to compile
|
|---|
| 179 | (transitional). Expect that G4Transportation8 will be taken away asap.
|

|
|---|
| 192 | - G4Transportation8
|

|---|
| 212 | - G4Transportation (hh,icc,cc)
|
|---|
| 213 | o Renamed G4CoupledTransportation to G4Transportation
|
|---|
| 214 | o Merged changes on branch used to bring in CoupledTransportation,
|
|---|
| 215 | porting changes in G4Transportation since the creation of

|
|---|
| 229 | ----------------------------
|
|---|
| 230 | - G4CoupledTransportation:
|
|---|
| 231 | o Make treatment of mass and full safety coherent (to-dos remain in
|
|---|
| 232 | G4PathFinder).
|
|---|
| 233 | o Added storing of full safety in state; retrieve it after compute step
|
|---|
| 234 | from PathFinder; calculate them same way at start of step.
|
|---|
| 235 | o Put back in the code for treating looping particles.
|
|---|

|
|---|
| 242 | ----------------------------------
|
|---|
| 243 | - G4Transportation: call PropagatorInField to clear state for new track
|
|---|
| 244 | --> addresses reliabilitiy problem seen by Atlas. This fix is related
|
|---|
| 245 | to overlaps, clearing the safety value (which is multivalued due
|
|---|
| 246 | to the overlaps, and thus can become invalid for a new track in
|
|---|
| 247 | an overlap region.)
|
|---|
| 248 |

|
|---|
| 255 | ---------------------------------
|
|---|
| 256 | - G4CoupledTransportation:
|
|---|
| 257 | o AlongStepGPIL() now returns an estimate for the safety for all geometries
|
|---|
| 258 | to make up for the fact that some other processes only have PostStep GPILs
|
|---|
| 259 | which cannot currently influence safety.
|
|---|
| 260 | - NOTE: Fix / Workaround for deficiency of others.
|
|---|
| 261 |
|
|---|
| 262 | November 13th, 2006, J.Apostolakis transport-V08-01-01

|---|
| 276 | - Corrected problem with suspended tracks - PR# 802.
|
|---|
| 277 | - Added StartTracking() method which takes over responsibility to
|
|---|
| 278 | clear the state for a new track, and to message other relevant
|
|---|
| 279 | component to clear their state (problem report and proposed revision
|
|---|
| 280 | by P.MoraDeFreitas).

|
|---|
| 283 | ------------------------------
|
|---|
| 284 | - G4Transportation:
|
|---|
| 285 | o The particle's charge is now taken from the dynamic particle, so that
|
|---|
| 286 | it can take into account changes from the interaction of an ion with
|
|---|
| 287 | matter (eg stripping e-). (V.Ivantchenko)

| 638 | - Fix for the new updating of the time for fields -- correcting previous
|
|---|
| 639 | tag. By keeping account whether the field changes the energy (and
|
|---|
| 640 | therefore the velocity) in the field manager.
|
|---|
| 641 |
|
|---|
| 642 | Requires and co-works with
|
|---|
| 643 | - "field-V03-02-07"
|
|---|
| 644 | - "geomvol-V03-02-02"
|
|---|
| 645 | in order to compile (let alone have any effect.)

|
|---|
| 648 | ---------------------------
|
|---|
| 649 | - Motivated by the use case of an Electric Field,
|
|---|
| 650 | * in order to achieve reasonable accuracy in time integration,
|
|---|
| 651 | * and to enable fields that vary with the global time
|
|---|
| 652 | changed Transportation to try to obtain the delta_time from FieldTrack.
|
|---|
| 653 | Co-works with and requires "field-V03-02-03" to have any effect.

| 656 | ------------------------
|
|---|
| 657 | - Fix in G4Transportation.cc for initialisation of touchable handle.
|
|---|
| 658 |
|
|---|
| 659 | Nov 8, 2001 G. Cosmo - transport-V03-02-03
|
|---|
| 660 | ------------------------
|
|---|
| 661 | - Introduced changes to G4Transportation for reference-counted
|
|---|
| 662 | touchables (R.Chytracek). Added methods GetFreeTouchable() and
|
|---|
| 663 | SetTheOtherTouchableFree(G4VTouchable*).

|
|---|
| 666 | ------------------------------
|
|---|
| 667 | - Added protection in G4Transportation::AlongStepGPIL for messaging
|
|---|
| 668 | "ResestStepEstimate" of ChordFinder for the case there is no global field.
|
|---|
| 669 | ** NOTE this is not a perfect resolution (see NOTE in log file). **

| 676 | Aug 16, 2001 J. Apostolakis
|
|---|
| 677 | ------------------------------
|
|---|
| 678 | - Erasing state information from previous track at the first step of
|
|---|
| 679 | each track. (-> this is required to ensure repeatability)
|
|---|
| 680 | This should eliminate any non-repeatability due to the propagation
|
|---|
| 681 | in field.
|
|---|
| 682 | ( Requires updated version of G4ChordFinder )

|
|---|
| 685 | ------------------------
|
|---|
| 686 | - Synchronised with CVS HEAD after introduction of warrenty disclaimer.
|
|---|
| 687 | - Modified author list in G4Transportation (P.Gumplinger).

|
|---|
| 690 | ------------------------------
|
|---|
| 691 | - Corrected the last update of G4Transportation.cc, which overwrote the
|
|---|
| 692 | value of the spin in the cases where a particle was not charged (eg photon)
|
|---|
| 693 | or a charged particle was not in a field.
|
|---|
| 694 |
|
|---|
| 695 | Apr 11, 2001 P. Gumplinger transport-V03-01-01
|
|---|
| 696 | -----------------------------
|
|---|
| 697 | - Updated G4Transportation.cc to make spin tracking work correctly:
|
|---|
| 698 | o Replaced the line originally commented out:
|
|---|
| 699 | // fTransportEndPolarization= aFieldTrack.GetSpin() ; // Not yet possible
|
|---|
| 700 | with:
|
|---|
| 701 | fTransportEndSpin = aFieldTrack.GetSpin();
|
|---|
| 702 | o Added to the AlongStepDoIt() the following call:
|
|---|
| 703 | fParticleChange.SetPolarizationChange(fTransportEndSpin);
|
|---|
| 704 |
|
|---|
| 705 | Mar 19, 2001 J. Apostolakis transport-V03-00-01
|
|---|
| 706 | ------------------------------
|
|---|
| 707 | - G4Transportation modified to use new FieldTrack, and get Kinetic
|
|---|
| 708 | Energy from it.
|
|---|
| 709 | This new FieldTrack together with changes in associated Equation of Motion
|
|---|
| 710 | classes implement the momentum vector as independent variable in place of
|
|---|
| 711 | the velocity.
|
|---|
| 712 | So this tag requires
|
|---|
| 713 | - new geometry/magneticfield tag "field-V03-00-01", and
|
|---|
| 714 | - new geometry/volumes tag "geomvol-V03-00-03" for new
|
|---|
| 715 | G4PropagatorInField ().

|
|---|
| 718 | ------------------------------
|
|---|
| 719 | - G4Transportation.cc:
|
|---|
| 720 | * Modified calculation of energy at the end of field step
|
|---|
| 721 | to make it more accurate at low velocities,
|
|---|
| 722 | (while remaining correct at high gammas).
|
|---|
| 723 | This improves the energy determination.
|
|---|
| 724 | Together with electromagnetic/standard tag "stand-V03-00-03"
|
|---|
| 725 | this addresses the main problem in propagating in an electric field
|
|---|
| 726 | (Problem report # 108 )

|
|---|
| 729 | ---------------------------
|
|---|
| 730 | - G4Transportation.cc:
|
|---|
| 731 | o added formula for Tkin corresponding directly to
|
|---|
| 732 | relativistic definition of Tkin = Etot - mc^2 = mc^2(gamma -1),
|
|---|
| 733 | where gamma is a particle Lorentz factor.
|
|---|
| 734 | o general cosmetics.

|
|---|
| 737 | ------------------------------
|
|---|
| 738 | - G4Transportation.cc: Set the True Step Length in G4Transportation.cc
|
|---|
| 739 | - Cosmetic: updated other files to the head, as there were no differences
|
|---|
| 740 | from it (CVS headers).

| 742 | May 15, 2000 J. Apostolakis (transport-V01-01-01)
|
|---|
| 743 | ------------------------------
|
|---|
| 744 | - G4Transportation.cc: Set the material in materialChange, in order to get
|
|---|
| 745 | correct behaviour for volumes that parameterise the material.
|
|---|
| 746 | (Fix is dependant on changes to particleChangeForTransport and StepPoint)
|
|---|
| 747 | - Modified setting of touchable change, in order to preserve const-ness where
|
|---|
| 748 | it exists.

| 750 | Nov 25, 1999 J. Apostolakis (transport-V00-01-01)
|
|---|
| 751 | ------------------------------
|
|---|
| 752 | - G4Transportation.cc: Added protection for the case of a zero step (when
|
|---|
| 753 | there is a field)
|
|---|
| 754 | - G4UserSpecialCuts: protection to use min range and min kinE only for
|
|---|
| 755 | charged particles.

|
|---|
| 757 | June 9, 1999 J. Apostolakis (transport-01-00-02)
|
|---|
| 758 | ------------------------------
|
|---|
| 759 | - Added a protection so that full relocation is not used for very small moves.
|
|---|

|
|---|
| 761 | Dec 4, 1998 J. Apostolakis (transport-00-04-01)
|
|---|
| 762 | ------------------------------
|
|---|
| 763 | - The Velocity Vector for Transport in a magnetic field is now set correctly.
|
|---|
| 764 | (previously the scalar velocity was automatically promoted to a 3-vector)
|
|---|
| 765 |
|
|---|
| 766 | Nov 25, 1998 J. Apostolakis
|
|---|
| 767 | -----------------------------
|
|---|
| 768 | - Added the direction to LocateGlobalPointAndUpdateTouchable.

|---|
| 770 | Nov 19, 1998 J. Apostolakis (transport-00-03-04)
|
|---|
| 771 | ------------------------------
|
|---|
| 772 | - Fixes:
|
|---|
| 773 | 1) The final energy is set equal to the initial energy, because
|
|---|
| 774 | the PropagatorInField does not calculate it correctly yet. NEEDS Fix
|
|---|
| 775 | 2) If the requested step size is zero and safety is zero, the
|
|---|
| 776 | step is now considered geometry limited. (This can happen
|
|---|
| 777 | if a discrete process tries to take a step that is very small
|
|---|
| 778 | compared to the mean free path.) Problem observed by Laszlo in EM tests.
|
|---|
| 779 | 3) PostStepGetInteractionLength now returns DBL_MAX, not kInfinity.
|
|---|

|
|---|
| 781 | Nov 11, 1998 J. Apostolakis (transport-00-03-03)
|
|---|
| 782 | ------------------------------
|
|---|
| 783 | - Changes to accomodate new interface of Field:
|
|---|
| 784 | G4PropagatorInField and G4FieldTrack.
|
|---|
| 785 |
|
|---|
| 786 | Oct 30, 1998 J. Apostolakis (transport-00-03-02)
|
|---|
| 787 | -----------------------------
|
|---|
| 788 | - In the case of magnetic field, a flag that determines whether the
|
|---|
| 789 | geometry limited the step was not set.
|
|---|
| 790 |
|
|---|
| 791 | Sep 16, 1998 J. Apostolakis (transport-00-03-01)
|
|---|
| 792 | -----------------------------
|
|---|
| 793 | - Checks whether the particle is out of the world volume,
|
|---|
| 794 | if so it has exited and must be killed.
|
|---|
| 795 |
|
|---|
| 796 | Aug 28, 1998 J. Apostolakis
|
|---|
| 797 | -----------------------------
|
|---|
| 798 | - The PostStepGetPhysicalInteractionLength has fixed (to return kInf)
|
|---|
| 799 | The boolean flags for touchables are now initialised. & Other small fixes ?
|
|---|
| 800 | Test code for non-relocating case added (for debugging).

| 802 | June 08, 1998 J. Apostolakis (trans-06-04)
|
|---|
| 803 | ------------------------------
|
|---|
| 804 | - Corrected Safety computation for the case of the field (adding endpoint
|
|---|
| 805 | distance instead of curve length.)
|
|---|
| 806 | - Added PostStepDoIt method that tries to relocate the particle using
|
|---|
| 807 | G4ParticleChangeForTransport
|
|---|
| 808 | - Transportation is no longer a G4ContinuousProcess.
|
|---|
| 809 |
|
|---|
| 810 | June 08, 1998 J. Apostolakis (trans-06-03)
|
|---|
| 811 | ------------------------------
|
|---|
| 812 | - Modified it to recomputate Safety at the start of a step. To do this
|
|---|
| 813 | it uses the previous step's calculated safety and endpoint.
|
|---|
| 814 |
|
|---|
| 815 | June 08, 1998 J. Apostolakis (trans-06-02)
|
|---|
| 816 | ------------------------------
|
|---|
| 817 | - Modified it to add re-computation of Safety at the endpoint of a step,
|
|---|
| 818 | when the safety would become negative. This is done to allow processes
|
|---|
| 819 | to benefit from a realistic (geometrical) value of the safety. The
|
|---|
| 820 | request to do this was from EM physics
|
|---|
| 821 |
|
|---|
| 822 | June 03, 1998 J. Apostolakis (trans-06-01)
|
|---|
| 823 | ------------------------------
|
|---|
| 824 | - The safety we is now generalised to mean the limit of assumption of all
|
|---|
| 825 | processes. The AlongStepGPIL input value is not the remainder from the
|
|---|
| 826 | previous step's geometrical safety.
|
|---|
| 827 | So the transportation must recalculate the starting point's safety here.
|
|---|
| 828 | As a zeroeth order approximation we set it to zero.

|
|---|
| 831 | ------------------------
|
|---|
| 832 | - A new process, G4UserSpecialCuts, was added to allow the
|
|---|
| 833 | user an alternative method to set some user cuts.

| 835 | April 15, 1998 H. Kurasige [recorded by John Apostolakis]
|
|---|
| 836 | ---------------------------
|
|---|
| 837 | - The transportation does the absolute minimum required to conform to
|
|---|
| 838 | the new scheme for ParticleChange: G4VParticleChange is used in signature.
|
|---|
| 839 | [ But default G4ParticleChange is still used ].
