Nature of problem:
We have developed an interactive software package suitable to design a transition radiation detector. The transition radiation yield of ultrarelativistic charged particles both from multilayered regular radiators and foam slabs is calculated. The program evaluates the number of photons emitted by the radiator, the number of the photons converted in the following gaseous detector and the relative energy distributions.
Monte Carlo simulation
For each set of input parameters, the program typically produces a 23 K bytes output file. The choices of the scanning parameters "menu" should take into account the file size to avoid problems for the user disk space allocation. Attention should be paid by the user also in the choice of the input design parameters so that the energy of a single transition radiation x-ray does not exceed 100 kev.
Depending on the kind of radiator selected (regular or foam), the typical VAX-11/780 CPU time in seconds is respectively about 15 times the number of runs and 70 times the number of runs for 5000 events.
