Subject: [How To] Stop Runs (October 2016)  
All AIDA operations are controlled from the Dell T410 Workstation aidas1 using web browsers.

AIDA has multiple, independent data acquisition servers connected by an Ethernet network.

Response times to commands, information updates etc are ~10-60s - please be patient!


How to Stop Run

1) Workspace 2 - Firefox web browser - TapeServer tab

   Select 'Reload'

   Check number of blocks written to disk is increasing

   See attachment 1

   If TapeServer data rate is zero see https://elog.ph.ed.ac.uk/AIDA/303

2) Workspace 2 - Firefox web browser - MERGE tab

   Select 'Reload'

   Check merge rate (~0.5-2M data items/s)

   Check state of *all* data acquisition servers is 'going'
