Presentation from MP3

Sunday 21^st March 2010

Re-establish 450 GeV beams
Measure and correct the optics and beam parameters at 450 GeV - done
Ramped at 3.5 TeV with B2 only- lost B1 due to LBDS trigger.
20:30 - 00:30 : Measure and correct the optics and beam parameters at 3.5 TeV.
00:30 : Ramping down and access in pt 6 for LBDS
02:00 - 08:00 : Damper setting-up at 450 GeV

Presentation at the 09:00 meeting

Saturday 20^th March 2010

Morning : Tunnel access (replacement of RCBYHS4.R2B2 PC - investigation on current lead RQTL9.R3B1)
Until 14:00 / 15:00 : 450 GeV recovery
15:00 - 21:00 Performed injection and beam dumping systems checks at 450 GeV
21:00 - 23:00 3.5 TeV ramp : Arrived at 3.5 TeV. Corrected the orbit - RQTF tripped.
23:00 - 07:00 : Ramp at 3.5 TeV and optics measurements at 3.5 TeV - 2 ramps were successfully done - Beams were lost shortly after the end of the two ramps (magnet trips and cryo temp. sensor)

Presentation at the 09:00 meeting
