| Abstract | Almost all accurate and efficient 2D large-signal codes for klystron simulations are proprietary and are not freely available to the wider klystron community. The klystron code KlyC1D/1.5D has been developed at CERN recently, as an attempt to bridge the gap between the fast, but approximate 1D models and the time/resource consuming PIC codes. Here the notation 1D/1.5D is related to the fact that KlyC can choose between a 1D or 2D map of the electric field, while the particle motion is one-dimensional. KlyC is available in the public domain. This paper should help users to start with KlyC simulations. CGUN as a beam optics simulation tool is also included in this package, which allows users to simulate 2D optics problems in Klystrons and another linear beam devices. Note, major updates comparing with version 5: 1) Small bugs fixed and improved performance and reliability 2) Uninterrupted graphical plot without stealing the focus 3) CGUN implemented into the package |
