Modified Elements

• The WIGGLER element was upgraded:
  • Includes vertical focusing effects.
  • Now allows even or odd number of poles.
  • Wiggler strength can be specified via the K parameter, instead of the radius.

• The SCRIPT element now allows creation of particles by the script. Previously, the number of particles returned by the script had to be equal to or less than the original number. This is useful, for example, in simulating shower creation and transport in a beamline using the shower program. Also added the START_PASS and ON_PASS parameters
• Added the ON_PASS parameter to the CENTER element, so that the centering can be applied only on the specified pass through the system.
• For particle output via WATCH elements, the LABEL input is now put in a parameter (``Description'') in the output file.
• The BMAPXY eleement will now use Bx and By columns (field in Tesla) if Fx and Fy (normalized field) are not provided.

• Upgraded the ZTRANSVERSE element. These improvements were suggested by Yong-Chul Chae:
  • Added WAKES and WAKE_INTERVAL parameters to allow getting wake data in an SDDS file.
  • Added FACTOR, XFACTOR, and YFACTOR parameters, which allow multiplying the impedance by factors.
