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)
| Name | Unit | Description | Default | |
| w1 | m | Width at the guide entry | ||
| w2 | m | Width at the guide exit. If zero, sets w2=w1. | 0 | |
| l | m | length of guide | ||
| R0 | 1 | Low-angle reflectivity | 0.995 | |
| Qc | AA-1 | Critical scattering vector | 0.0218 | |
| alpha | AA | Slope of reflectivity | 4.38 | |
| m | 1 | m-value of material. Zero means completely absorbing. | 1.0 | |
| W | AA-1 | Width of supermirror cut-off | 0.003 | |
| nslit | 1 | Number of horizontal channels in the guide (>= 1) [1] | 1 | |
| d | m | Thickness of subdividing walls [0] | 0.0005 | |
| mleftup | 1 | m-value of material for leftup. oblique mirror | -1 | |
| mrightup | 1 | m-value of material for rightdown. oblique mirror | -1 | |
| mleftdown | 1 | m-value of material for rightdown. oblique mirror | -1 | |
| mrightdown | 1 | m-value of material for leftup. oblique mirror | -1 | |
| mleft | 1 | m-value of material for left. vertical mirror | -1 | |
| mright | 1 | m-value of material for right. vertical mirror | -1 | |
| G | m/s2 | Gravitation norm. 0 value disables G effects. | 0 |
