Optical Elements and Keywords, Complements

ThisOptical elements chapter is not a review of the \(60+\) optical elements of zgoubi’s library. They are described in the Users’ Guide. One aim here is, regarding some of them, to briefly recall some aspects which may not be found in the Users’ Guide and yet addressed, or referred to, in the theoretical reminder sections and in the exercises. This chapter is not a review of the \(40+\) monitoring and command keywords available in zgoubi, either. However it reviews some of the methods used, by keywords such as MATRIX (computation of transport coefficients from sets of rays), FAISCEAU (which produces beam emittance parameters), and others. This chapter in addition recalls the basics of transport and beam matrix methods, in particular it provides the first order transport matrix of several of the optical elements used in the exercises, in view essentially of comparisons with transport coefficients drawn from raytracing, in simulation exercises.
