MDC Parts list
1. 4-6way cross for 45 degree line
5 cross for the 45 degree beam line flag.
| Parts | Quantity | Link |
| 5-way cross | 1 | 5-way cross |
2. 5-6 way cross for 90 degree line
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 |
| 5-way cross | either one 6-way or 5-way cross. | 5-way cross |
| 6-way cross | either one 6-way or 5-way cross. | 6-way cross |
3. Double side Flange for Jlab Flag 3
I need to check if we have it or not.
