APS beamlines can report questionable or poor beam quality via EPICS PVs( |
Beam Quality Displays and Macro Variables |
beamQualityReport.adl - Located on all DSERVs at
sNNdserv:/APSshare/adlsys/site/beamQualityReport.adl Users may indicate changes in status of the beam quality on the beamQualityReport screen. The screen will then change to the beamQualityReportForm.adl screen so the user can enter further information.

Beam Quality Report PV's |
Variables used below (make appropriate substitutions to fit your beamline):
BL = BM or ID
## = 2-digit sector number (i.e. 01)
[us/ds] = us or ds (Only used for canted beamlines)
So some example PVs would be the following:
BeamQualityReport:BM08:Status
BeamQualityReport:ID18:Form:Name
BeamQualityReport:ID21ds:Form:Size |
BeamQualityReport:BL##[us|ds]:Status – Reported beam quality for individual beamline.
BeamQualityReport:BL##[us|ds]:Comment – Operator comment concerning the current state of the investigation into the beam quality local to your beamline. This is only settable by Operations. BeamQualityReport:BL##[us|ds]:Form:Name – Name of person submitting the form. BeamQualityReport:BL##[us|ds]:Form:Rate – Rate at which the problem is observed.
BeamQualityReport:BL##[us|ds]:Form:Intensity – Beam intensity experienced.
BeamQualityReport:BL##[us|ds]:Form:Size – Beam size indication.
BeamQualityReport:BL##[us|ds]:Form:Position – Beam position indication.
BeamQualityReport:BL##[us|ds]:Form:Variation – Beam variation when the problem is occurring.
BeamQualityReport:BL##[us|ds]:Form:Contact – Contact phone number for person reporting. BeamQualityReport:BL##[us|ds]:Form:SubmitTime – Timestamp indicating when the form was received by Operations. This is only settable by Operations. BeamQualityReport:BL##[us|ds]:Form:Submit – Submit the form.
BeamQualityReport:Global:Count1or2 – Total number of beamlines reporting questionable beam. |
Beam Quality Reporting Access Security |
The access security mode for beamline steering PVs (ID and BM) is based on the sectors insertion device access security mode. |
