 h1. What to do when something happens on shift 

 Shifter information for various problems that may be encountered on shift 

 h2. Shifter Instructions or What to Do on Shift 

 "What to do on-shift : MICE Shifter Training":http://micewww.pp.rl.ac.uk/documents/144 

 As part of your shift you should keep a record of people present, the main parameters of the 
 run and incidents that occurred during the run. A good example is shown in the  

 Guide to using the eLog for shift : attachment:Shifter_Elog_Guide.pdf 

 Note that in the example given in this guide, the shifters were explicitly asked to check the temperature differentials 
 in the conventional magnets every half hour.  

 h2. How to launch and work with the Run Control 

 "Using the Run Control GUI [2015]":http://micewww.pp.rl.ac.uk/documents/135 

 h2. Shifter checklist : How to start a run 

 "Shifter checklist to start a MICE run":http://micewww.pp.rl.ac.uk/documents/136 

 h2. Where to find the CDB Viewer 

 The CDB Viewer can be found at    http://cdb.mice.rl.ac.uk/cdbviewer/ 

 h2. Shifter Target Training and what to do when.... 

 "The RATS daemon crashes":http://micewww.pp.rl.ac.uk/projects/operations/wiki/ShifterTrainingTarget 
 "A BPS error is encountered":http://micewww.pp.rl.ac.uk/projects/operations/wiki/ShifterTrainingTarget 
 [[BeamlineProcsEarthLeakTrip|... a conventional magnet trips off]] 
 [[BeamlineProcsTargetFail|... the target throws an error]] 
 ... beamline polarity sensors misbehave: [[BeamlineProcsTestPOMPOMs|check voltages]] (until the proper user guide is finished) 
 [[BeamlineProcsDSThermalTrip|... Decay Solenoid PSU trips off]] 

 h2. What if one of the MICE thin clients crashes? 

 Very rarely one the thin clients can crash like this https://micewww.pp.rl.ac.uk/elog/Shift+summary/150623_043853/MICETHIN02_error_230615.JPG 

 The current response to this is : 

 If the applications that had been running on the machine can just be opened elsewhere, then they should be, and an email 
 should be sent to the online expert (Paolo). If the process hasn't been released by the machine, and can't be run 
 in multiple instances (i.e. RunControl) then the SOC should be called, who will in turn probably call the online 
 expert. 

 h2. What if an error from the DataMover is reported from Run Control 

 If an error is reported via Run Control then the shifters don't NEED to do anything - they can 
 carry on with the next run; all that will happen is that the data distribution will be delayed.  

 Make an eLog entry, then wait until a suitable time when DAQ is stopped (e.g a shift change) and run the manual 
 script. If it still doesn't work, eLog the error and escalate to (for now) Henry. 

 Instructions to run the datamover manually can be found in the Red Binder and in the latest version of "the datamover instructions":http://micewww.pp.rl.ac.uk/documents/10
