Guide_honeycomb
ComponentModels a honeycomb guide tube centered on the Z axis. The entrance lies in the X-Y plane. Gravitation applies also when reaching the guide input window. The guide can be channeled (hexagonal channel section; nslit,d parameters). The guide coating specifications may be entered via different ways (global, or for each wall m-value). For details on the geometry calculation see the description in the McStas reference manual. Example: Guide_honeycomb(w1=0.1, w2=0.1, l=12, R0=0.99, Qc=0.0219, alpha=6.07, m=1.0, W=0.003, nslit=1, d=0.0005) Example values: m=4 Qc=0.02 W=1/300 alpha=6.49 R0=1WARNING: This is a contributed Component.
