---|
11 | The MATRIX permits the definition of an arbitrary transfer matrix. |
---|
12 | It has four real array attributes: |
---|
13 | <ul> |
---|
14 | <li>L: |
---|
15 | Length of the element, which may be zero. |
---|
16 | <li>KICKi: |
---|
17 | Defines the kick of the element acting on the six phase space coordinates. |
---|
18 | </li><li>RMik: |
---|
19 | Defines the linear transfer matrix (6*6) of the element. |
---|
20 | </li><li>TMikl: |
---|
21 | Defines the second-order terms (6*6*6) of the element. |
---|
22 | </li></ul> |
---|
23 | Data values not entered are taken from the identity transformation, |
---|
24 | kick and second order terms are zero as default. In the thin-lens |
---|
25 | tracking module the length of an arbitrary matrix is accepted, however |
---|
26 | no second order are allowed to avoid non symplectic tracking runs. In |
---|
27 | the latter case the tracking run will be aborted. |
