- Add a link directly from the BIS to the retrigger lines- Connect the CIBDS as User on a CIBM to avoid spurious asynchronous beam dumps
S. Gabourin – 31st October 2014
From v1 to v2/3
Updates v1 → v2:
- Change the lemo connector to the CIBU
- To simplify soldering
- Bad for CIBU commissioning…
- LED inversion, …
v1 v2
Updates v2 → v3:
- Change polarity for the “PLC local mode” read
back
- Add resistors to
- Protect output to the CIBU
- Protect output to the TD Box
- Get exactly 12V pulse for the TD Box
v3 NOT in operation as not working properly !

Experience from LBDS reliability run

Installation in UA63 & UA67
Full rack for:- The BIS FEC
- CIBG B1- CIBM B1- CIBM B2- CIBDS B1
- The CIBU of the CIBDS- The 2 Trigger Delay boxes (+ 1 spare)
Better to have a “how to plug” patch- For optic fibers- For electrical cables

Arming sequence:After some time, done by the sequencer, but before…
→ use of Nodal
Quite challenging to arm and maintain both beams:
4 TSU + 2 CIBDS + 2CIBG to arm and start manually…
All within 5 sec…
→ Keep B1 and B2 independent
