  1. BGI status M. Sapinski, Emittance meeting 2013.01.16

  2. Difficult hardware restart • SPS: camera switched on, working correctly but lack of RS485 communication. • LHC: cameras switched on, HV as well, all tested on Tuesday and Wednesday. • On Thursday BGI crate (cfv-us45-btvm) found down (maybe electrical glitch played a role, but other BI crates OK), no remote control. • Interventions (Ion and Raymond, afterwards Stephan): • Exchange of Wiener power supply (Ion and Raymond) • Problem with one of the power strips inside the crate (exchange by electrical service called by Raymond) • Second power strip also found off (Stephan and Christophe) – powered on • After that communication with crate OK, but gas injection system found in “STOP interlock present” state. • Remote activation did not work, tunnel intervention was necessary (Didier and Francois) • System operational again on Monday afternoon.

  3. Lesson for the next time: AFTER CHRISTMAS TEST EVERYTHING ASAP because Santa does not exist
