19 March 2012 Muon Week - Operations 22

Status

• 3 months shutdown just over• Running since 2 weeks with 24/7 shifts• Many activities performed on Detector,

Infrastructure, HW + SW – MDT EE side C fully installed– RPC power, HV, gas, etc.– TGC chamber replacement + conditioning– MDT gas leaks and general overhaul– CSC Rod Firmware

– … and many more detailed reports afterwards

Priority:• Readiness for Highest Luminosity Running• Good and Stable Data Taking Conditions

19 March 2012 Muon Week - Operations 3

Agenda

19 March 2012 Muon Week - Operations 55

Cosmic Run (Solenoid ON Toroid OFF)• Conditions:

– Solenoid ON, Toroid OFF– MDT/CSC Ready (HV/LV OK), RPC Ready (but ~80% of HV channels ON), TGC Off

• Trigger:– RPC lower Sectors (10-16) Mu_4 mu_11, Calibration Stream on

• Minimum participating components: Muon ID (SCT+TRT) • List of Runs:

All events available on the tier0 Many Thanks to Data Preparation

Beam Splashes

• Beam 1 @ 23:37, March 14th

– run 199193, lb 200, event 12287 BCID 0 (1)– trigger 1 BC earlier

• Beam 2 @ 00:15 March 15th

– LB 238 ev 14656 BCID 202 (200) – “Too many hits in events” for many SSW at

BCID = 200 for TGC – Occupancy peak in all the MDT crates @ BCID

= 200 – Larg – triggering 1 or 2 BC earlier

• Data available for Analysis• EE status?

Improvements for next official ones?

MDT Occupancy

RPC DCS (peaks)

19 March 2012 Muon Week - Operations 7

Last Week Operation and Planning

• No Muon planning Meeting tomorrow March 20th

• Friday afternoon (Solenoid + Toroid slow dump)– DSS TGC, CSC, MDT – Magnets up again from Sunday ~14:00– TGC restart took longer (excluded)

• Access Requests:– RPC: Gas system (adjust exhaust bubblers) + HV checks– TGC: Investigate ROD A12 problem

• Open Issues from Atlas Run Meeting:– TGC:

• Problems with recovery/removal timeout• Problems at initialization• TTC partition restart

– RPC:• synchronization and killed trigger sectors

– CSC: • DQ Agent/Gnam Crash
