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

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

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

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

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

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

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
