Presented - Tim, Fernando, Stephanie, Keith H., Sasha, Scot, Chris S, Vlad B., Arshak
Topics for discussion
- 1) Design of HV distribution panels
- -Length of HV cables (inside the dark room)
- 2) Design of the LV distribution panels
- -Length of LV cables (inside the dark room)
- 3) Location of signal patch panel
Original layout the distribution boards and cables
HV distribution
- Distribution panels positioned in 4 quadrants of the FCAL dark box. 9 Radial cables connected from outside to each quadrant.
- Each distribution board feeds an array of 20x20 ECAL modules, i.e., one quadrant of the ECAL (layout modified)
- Radial connector orientation: 5 vertical and 4 horizontal [1]
- Use 9x4 = 36 CAEN A7030N modules (add 2 modules to provide the same layout of patch panels and symmetric distribution of HV cables over chains in dark room)
- HV cables inside the dark box (from dist boards to dividers) are routed through chains (left, right. top, bottom)
Questions:
- Exact location of distribution panels (hole size in the FCAL box)
- Length of cables
- Insulation
LV distribution
- Powered by 2 MPOD modules, 2 x 2 = 4 cables
- Use four (?) distribution boards positioned near the ECAL (change location). Each board is connected to 20x20 ECAL modules.
- New type of the LV connector and LV cable (shielded cable connected the divider and distribution board)
- Mount the distribution board on the 'plastic' rectangular beam pipe (or chains) ? Should be rigid.
- Plug the cable from the MPOD directly to the PCB (?)
- Distribute 4 LV cables along the beam pipe (similar to signal cables)
Need to order soon: HV and LV cables
