!Input file for the IMPACT-Z beam dynamics code:
!Here, all lines starting with "!" are comment lines.
!The 1st 11 lines (excluding comment lines) define the numerical
!parameters and beam parameters.
!The remaining lines define the accelerator elements line by line.

!"0.03" - x pipe half width (m), y pipe half width (m) and period length (m).
!those width are used to set up the external boundary in the case of
!finite transverse boundary condition. They are NOT used to check particle
!loss.
