ISIS_moderator
ComponentProduces a TS1 or TS2 ISIS moderator distribution. The Face argument determines which moderator is to be sampled. Each face uses a different Etable file (the location of which is determined by the MCTABLES environment variable). Neutrons are created having a range of energies determined by the E0 and E1 arguments. Trajectories are produced such that they pass through the moderator face (defined by modXsixe and modYsize) and a focusing rectangle (defined by xh,yh and dist). Please download the documentation for precise instructions for use. Example: ISIS_moderator(Face ="water", E0 = 49.0,E1 = 51.0, dist = 1.0, xw = 0.01, yh = 0.01, modXsize = 0.074, modYsize = 0.074, CAngle = 0.0,SAC= 1)WARNING: This is a contributed Component.
