| 19 | An ELSEPARATOR (electrostatic separator) has four real |
---|
| 20 | attributes: |
---|
| 21 | <ul> |
---|
| 22 | <li>L: |
---|
| 23 | The length of the separator (default: 0 m). |
---|
| 24 | <li>EX: |
---|
| 25 | The horizontal electric field strength (default: 0 MV/m). |
---|
| 26 | A positive field increases <i>p<sub>x</sub></i> for positive particles. |
---|
| 27 | <li>EY: |
---|
| 28 | The vertical electric field strength (default: 0 MV/m). |
---|
| 29 | A positive field increases <i>p<sub>y</sub></i> for positive particles. |
---|
| 30 | <LI>TILT: |
---|
| 31 | The roll angle about the longitudinal axis (default: 0 rad). A |
---|
| 32 | positive angle represents a clockwise of the electrostatic separator. |
---|
| 33 | </ul> |
---|
| 34 | A separator requires the particle energy |
---|
| 35 | (<a href="beam.html#energy">ENERGY</a>) |
---|
| 36 | and the particle charge |
---|
| 37 | (<a href="beam.html#charge">CHARGE</a>) |
---|
| 38 | to be set by a <a href="beam.html">BEAM</a> command |
---|
| 39 | before any calculations are performed. |
---|
| 40 | <p> |
---|
| 41 | Example: |
---|
| 42 | <pre> |
---|
| 43 | BEAM,PARTICLE=POSITRON,ENERGY=50.0; |
---|
| 44 | SEP: ELSEPARATOR,L=5.0,EY=0.5; |
---|
| 45 | </pre> |
---|
| 46 | The <a href="local_system.html#straight">straight reference system</a> |
---|
| 47 | for a separator is a cartesian coordinate system. |
