CRL

Function

To calculate the parameters of Compound Refractive Lenses (CRL).

Two kind of calculations are allowed:

1. main parameters (focal distances, gain, acceptance, etc.) (calculated using Refs. 1 & 2)

2. Pseudo-Ray-Tracing to compute the beam profile at the image plane and the phase-space plot. (calculated using Ref. 2, formulas 9 and 32 for cylindrical and parabolic lenses, respectively).

Documentation

• application doc

• input parameters

Technical aspects

• Numerical calculations are done using the IDL functions crl_calc_rt
