MDC Parts list
1. 4-6way cross for 45 degree line
5 cross for the 45 degree beam line flag.

2. 5-6 way cross for 90 degree line
Do we need Faraday Cup at the end of 90 degree?
We have one 3-way cross for this. But it is preferred to use 5-6 way cross, since we attach NaI detectors to it like we did in JLab PEPPo.
| Parts | Quantity | Link |
