Beam Lines

This chapter introduces beam transport and manipulations in beam lines. It provides the theoretical material resorted to in the simulation exercises, leaning on charged particle optics and beam manipulation concepts introduced in earlier Chapters. The simulation of beam lines and specific functionalities they ensure require new optical elements, such as WIENFILTER, EBMULT, high order multipoles, etc. Particle monitoring resorts to keywords introduced in the previous Chapters, including FAISCEAU, FAISTORE, possibly PICKUPS, and some others. Spin motion computation and monitoring resort to SPNTRK, SPNPRT, FAISTORE. Optics matching and optimization use FIT[2]. INCLUDE is sometimes resorted to, mostly in order to modularize and/or simplify the input data files. SYSTEM is used to, mostly, call gnuplot scripts so as to end simulations with some specific graphs, or animations. These scripts read their data from output files filled up during the execution of the code, such as zgoubi.fai (resulting from the use of FAISTORE), zgoubi.plt (resulting from IL \(=\) 2 flag), or other zgoubi.*.out files resulting from a PRINT command.
