Objectives

1) Improve connection reliability with crates in the pit

2) Enable remote monitoring of HV parameters

3) Enable remote control of HV parameters

4) Enable possibility for HV status logging

5) Allow possibility to send warnings to expert in case of malfunction

Aging problem

• Communication problem persist with TOF-R crate 4!

• Problems are typical aging problem (bad contact between connectors, chips and sockets etc…)

• Decide to open Crate 4 in very bad working conditions

• Communication restored, but we lose 2 HV distributors!

104 (11.6%)Before intervention:

ToF-R: 34 (random bad pixel)After intervention:

ToF-R: 30 (random bad pixel)+ 37 (due to the intervention, Crate 4)+ 22 (unknown reason, Crate 1)

Conclusion

• Control and monitoring hardware upgrade successful!

• For ION run, remote control, monitoring and data logging of HV status will be possible

• Problems: urgently needs for spare parts for CAEN HV system, TDC and QDC

• Without spare parts, the future will not be bright for ToF-LR!
