EGS[underscore]Windows2: An enhanced graphical interface to EGS

This report gives a general overview of the EGS[underscore]Windows2 program. The program is intended to be used to display individual particle histories of electrons, photons, and positrons generated by the EGS4 Code System. Much of this work is based on the earlier version of EGS[underscore]Windows2 from the Institute for National Measurement Standards at the National Research Council of Canada (NRCC). No attempt is made to modify their EGS subroutine WATCH, which is used to output the particle vectors to be read by EGS-Windows, or duplicate any of the documentation describing the subroutine. EGS[underscore]Windows2 reads data in the same format as produced by WATCH. Users of EGS[underscore]Windows2 are encouraged to obtain the original EGS[underscore]Windows report from the NRCC in addition to this report as complete documentation of EGS[underscore]Windows2. As in the original report, two levels of information are covered in this report: the user level, and the programmer level. The user level should be read by all users. It describes execution, operation, and capabilities. The programmer level should be read by those users who may want to modify the program or who would like a more detailed understanding. It describes briefly the routines and there function, as well as the major more » changes in the new release of the 3D graphics programming library Sun PHIGS 2.0. « less
