PRC Guide 2

• you are registered at CERN, have access rights to the ACR (and cafeteria), and wear a CERN cell phone• you have sufficient overlap with previous PRC

• get familiar with the experiment and its systems• grasp the style of the (short) daily meeting• learn about book-keeping (minutes, runs, etc)• attend a 14:00 LPC meeting in CCC

• you get keys for PRC office• you decide if you wish to be ‘coffee coordinator’ well in advance• if you are too tired, ask the RC for a break

Before your period starts

PRC Guide 3

• detector subsystems and their coordinators• DCS, DSS, handshakes, alarms, RP veto, SLIMOS duties, access formalities (access issues are TC matters!)

• ECS: runs, partitions, locks• Accumulated data, beam intensities, etc• CTP: configuration, trigger clusters, trigger classes• Filling schemes, machine jargon (see list of LHC acronyms on RC website)• communication with CCC• communication with RC, SL, SRC, and shifters

PRC Guide 5

• attend the daily LPC meeting in 874-1-011 (CCC) at 08:30 (working days) and 09:00 (weekend) report to SR• collect information from and inform SRC• chair the daily RC meeting at 17:30 • write and send daily RC minutes (post it in eLogbook, too)• keep planning and statistics files up-to-date and post them on the web• you may attend the trigger meeting. Useful links at http://aliceinfo.cern.ch/static/trigger/doc/index.html

• attend weekly LPC meeting on Monday at 14:00. Material can be found at http://indico.cern.ch/categoryDisplay.py?categId=1607

Tasks I

PRC Guide 6

• be present in ACR major part of the day and evening shifts

• keep track on subsystem and machine status (LHC websites). Transfer information to SRC

• setup and ensure, with SL, accomplishment of running plan

• check and ensure that data-taking is going according to plan

• communicate fluidly with SLs

• replace SL if necessary

• mind for a pleasant working atmosphere in ACR and WRs
