5 more MB2 Chambers (20–24) since 5th March Tested at CERN (HV) from 6th to 16th March and all found O.K , except one sparking strip (chamber 23). Strip and Wire disconnected, now all O.K A new mobile stand-alone chamber testing system setup at ISR:

HV: CAEN SY127 for test 1 SL. (Current Resolution:10nA)DAQ: One V767 TDC for test 1/2SL. TestPulse + Noise

It should be improved at the near future.

CIEMAT Tecnicians spent several days at ISR for gluing RPC pads

Replacement of HVB’s in chambers 7,8,9,11,12,13Depending on availability of boards and manpower

Chambers with pending HV problems at March 1st to be fixed 3,4,10,12,15 Chamber 10 repaired on March

Problems due to HVBoards.
