2. Andreas Lüdeke, Trieste, 24. Sep., WAO '07, 2 /14 Paul Scherrer Institute Swiss national research center 1300 employees Swiss Light Source Proton facility: 1 MW cw beam – Spallation neutron source PSI West: Large Research Facilities Proscan SC cyclotron – Cancer therapy A. Facchetti, WEPMR10: The new PSI central accelerator control room

3. Andreas Lüdeke, Trieste, 24. Sep., WAO '07, 3 /14 Swiss Light Source Injector – 100 MeV Linac – Full energy booster, 3 Hz – Long booster in ring tunnel Storage ring – Circumference 288m – E = 2.4 GeV, 400 mA top-up – Beam stability < 1µm Beamlines – Currently ~ 16 beamlines

4. Andreas Lüdeke, Trieste, 24. Sep., WAO '07, 4 /14 Who's communicating? System controls & diagnostics, events Operators Sys. Experts Accelerator Users Management Feedback Controls Shift protocol Bug reports Event DB Shift protocol Meeting minutes How to's “Digital User Office” ID gap control Broadcast messages Beamline status Acknowledge msg. Bug reports How to's Documentation Meeting minutes Diagnostics Alarms Events Regulations Schedules Procedures Shift protocols Event DB Statistics

5. Andreas Lüdeke, Trieste, 24. Sep., WAO '07, 5 /14 Accelerator: Alarms Using standard tool: EPICS alarmhandler – Features alarm hierarchy, acknowledgment, scripts, alarm logging – Write alarm history to relational database – Tool to browse and filter alarms, alarm tables for shift protocols PHP web interface to alarm history data

6. Andreas Lüdeke, Trieste, 24. Sep., WAO '07, 6 /14 Accelerator: Data Archives Using standard tool: EPICS channel archiver – Several 10 kHz data logging, – Sampling defined per channel, – Retrieval tool for very fast o retrieval, o filtering, o data correlation,... PHP web retrieval interface – Plot and export data – Up to 100 channels per plot – Two scalable Y axis

7. Andreas Lüdeke, Trieste, 24. Sep., WAO '07, 7 /14 Accelerator: Events Event database: automatic event logging – Define event types by rules: start and stop rule. – Each rule can read many control system channels. E.g. o Start “beamloss” → I beam < 50 mA o Stop “beamloss” → I beam ≥ I top-up & ID gaps closed. – Store in relational database: o Event start/end, event type and shift type. o Automatic links to event data Event cause assignment by machine expert: – Assign failure areas (LI, BO,...) and system (RF, VA,...) – Assign cause “fraction” in percent, provide failure description – Add additional links if desired

8. Andreas Lüdeke, Trieste, 24. Sep., WAO '07, 8 /14 Accelerator: Events cont. Event database web interface – Display all events and their related information for a time period – Allows to filter for event types and shift types

14. Andreas Lüdeke, Trieste, 24. Sep., WAO '07, 14 /14 Conclusion You already have all of this information, too. Somewhere. – Interconnect your data – Allow for data references → data access by URL's – Use a central place to store your data → relational database Central documentation system → use a Wiki Automatize your information flow → script access for all data Standardize your applications: e.g. one PSI logbook application Take all information sources into account, e.g. – Control system data – Planning data like shift plans and personnel roster – Shift and meeting protocols
