DESCRIPTION
TRANSCRIPT
status of the machines over X-mas standby period, services required and plans for rapid start-up
OP Group Meeting
KH
• cooling circuits require 200-300 kW heat load in order not to freeze• circuits of the equipment must not be separated from the main cooling circuit • for the temperature surveillance (BE/OP/TI) alarms must be available
cooling circuits
KH
facility cooling circuit load (present or required)
Linacs and LEIR FDED-00049 enough heat load
PSB + TT2 FDED-00065 need to generate load
PSB F$FSEG-00361 need to generate load
PS FDED-00050 centre anneau need to generate load
PS FDED-00032 aimant PS need to generate load
PS F$FSEG-00355 need to generate load
PS FTEB-00046 POPS need to generate load
SPS enough heat load
North Area enough heat load

cooling circuits - IEFC 19/10/12
• CV will intensify the rounds during the closure especially if the weather is cold.
• On Monday January 7th , CV will restart :• PS : FDED-00032 PS Magnet• POPS: FTEB-00046
• POPS will be fully operational on Tuesday.

cooling circuits - IEFC 19/10/12
6. February 2012: a good example
• Extremely cold and windy weather • All the primary circuits were running with a reduced load. • Large amount of problems on drinkable and fire hydrant circuits but the
primary circuits had well resisted • POPS start up was delayed because the filling circuit was frozen →
corrective work acheived.

* EN/CV and EN/EL provide always piquet service
• ‘best effort’ service during working hours, but somebody must be reachable• piquets which are not required (magnets, kickers, LL RF, … do not appear)• magnets: in case of water leaks best effort
OP: TI plus support from beam operators plus supervisor
Linac3 (see EDMS 1235164):• source pulsing, beam on source beam stopper• most converters on• RF off• vacuum maintained
LEIR:• all converters off• RF off• magnetic cycle prepared in case of re-start• vacuum maintained
