Former LUCID probes G Avoni - D. Caforio LUCID BOLOGNA meeting11 Updated recent offer for a q.ty of 50 pcs: 55€ each (cable provided by CERN)

Final considerations Need 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 G Avoni - D.
