LUCID services

G Avoni - D. Caforio 10.12.2013 - LUCID BOLOGNA meeting 1

Main topics:

• HV scheme (additional connections in pocket)

• Temperature probes

• New offers from AXON for rad-hard cables for :

• Temp. probes , in alternative to former CERN 2x2xAWG26 cable• PMT signals, in alternative to CERN CC50 thick brown cables

Connectors for PT100 probes

G Avoni - D. Caforio 10.12.2013 - LUCID BOLOGNA meeting 5

• Probes for the front PMTs AND RO PMT box in the pocket:SUB-D37 or SUB-D25 mating connectors, solder type (in this picture: SUB-D37)

• LED diffusers:LEMO FFA.0S.304.CLAC44 + PCA.0S.304.CLLC44 (cable diam. 3.8 - 4.4 mm)

• Updated recent offer for a q.ty of 50 pcs: 55€ each (cable provided by CERN)

Final considerationsNeed to define as soon as possible:

• Number and place of temperature probes• Type of cables for probes and PMT signals to order (compatibly also with the

outcome of irradiation tests from Tapiro and available budget)• Realistic drawing of RO box to be put in the pocket
