MDC Parts list
1. 4-6way cross for 45 degree line
1) 5 way cross for 45 degree.
2) Blank-off or view port. (If we borrow the view port 0 degree, we need to buy a blank-off for 0 degree.)

| 5-way cross | 1 | 5-way cross |
| View Port | 1 | Where did we ordered last one. [View Port] |
| Blank off | Need to count | Blank off |
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.
