Starting and Stopping a Beamtime¶

The Start/Stop-script can only be executed by the beamline-staff groups, e.g. p11staff, FS-EC and IT

Start a Beamtime¶

ssh username@psana001.desy.de

[psana001.desy.de]$ startBeamtime --beamtimeId <beamtimeID> --beamline <beamline>

Archive for Proposal P Beamtimes¶

Since 2017-06-28, proposal P beamtimes (or "Industry Beamtimes") will not be archived and a single copy remains on the core filesystem. If you wish to enable the archiving for such beamtimes, add the option "--archive" to the invocation of the startBeamtime script, e.g.:

The startBeamtime script will also print a message before the no/yes prompt, if archiving is disabled.

For beamtimes with proposalType P, automatic archiving is disabled by default.
If you wish to enable archiving for this beamtime, abort and add
'--archive' as an option to the script.

Do you really want to start beamtime '<beamtime>'? [no/Yes]

Archiving for this beamtime has been requested.
Do you really want to start beamtime '<beamtime>'? [no/Yes]

Stop a Beamtime¶

ssh username@psana001.desy.de

[psana001.desy.de]$ stopBeamtime --beamtimeId <beamtimeID> --beamline <beamline>

The directory 'current' will be un-linked and thus the data will cease to be visible on the beamline file-system. The data created during this beamtime remains visible in the core file-system.
