1. Muon Shift Organization Outline Class 1 Atlas Control Room Shifts Booking Present Status + Experience+ Feedback Class 2 reminder A. Polini & Z. Yan May 21 th 2012

2. Class 1 Control Room Muon Shifts Following Steering and IB discussions in November: max 3 people per institute doing at 12 shifts in 3 months we got ~ 110 names from ~ 50 institutes Some groups (in particular those who didn’t have a chance of shifts in 2010 could book a week in advance) 2012 Status: Few hours after opening the booking all shifts filled Several groups had no chance to get shifts No easy solution available – Indeed not enough class 1 shifts available within Muons – ATLAS is always missing Shift Leaders, Run Control, SLIMOS, Trigger etc. Future options: Reduce the institution quota Adjust the institute shift quota/credits according to the size of the participating group One idea we personally liked from last IB: Shadow shifts (with partial OTP credit) especially targeted to get young people involved in detector operations Reminder

3. Booking: Present State Muon RC personal experience: True that Shift Calendar always almost fully booked But some free slots appearing from time to time (so far 5 x 3-4 shifts) required in some cases short term action One week-end night shift was cancelled about 24 hours before shift start. Luckily we could find a replacement. Need know far more in advance

4. Muon Shifter Documentation

5. Shift Organization and Feedback Quality of Muon Shifters? – Status of training (4 modules + regular updates) – Feedback from detector experts? – Require more and better shadow shifts? Shifter Operation? – Better expert-ACR shifter communication required – Experts are requested to always post E-log entries – Whiteboard twiki page should be the place of posting any useful information and instruction by on-call experts – Some system and procedure description still too complicated and unreadable – Need for detector components to follow up closely development and improve items which appear weak in operation Feedback and Discussion ……

6. Class 2 shifts (Muon Experts) Status: Situation of experts partially static (few more experts in MDT community) OTP class 2 shifts reduced w.r.t. 2011 MDT/CSC/TGC moved to primary, secondary on call shifts where secondary on calls are credited 50% of the tasks Future: Long term situation uncertain. Several expert on call tasks are (still) covered by very few (2-4) individuals all year round, which might not work after 2012
