- Overview of online systems
- scope of online effort
- trigger and data rates
- number of detector channels, front-end boards, HV and LV channels, crates, hardware controls channels, monitoring hist, computers, network connections, etc.
- Software foundations
- cMsg pub/sub interprocess communication system
- ET system
- EVIO data format
- Trigger/DAQ
- overall trigger
- adapting CODA toolkit to Hall D
- implementation plans for low luminosity prototype farm
- event transfer to silo
- scaling to high luminosity and full L3 farm
- Controls
- slow controls
- architecture - 3-tier, functional view vs implementation view
- strategy - control loops, PLC usage, CAN, I2C, SNMP, OPC, etc.
- component choices (tentative)
- interoperability with accelerator control system
- experiment controls
- run control using AFECS, inclusion of non-CODA components
- generic high-level state machines
- slow controls
- Monitoring
- detector
- via slow controls system
- via data stream when running
- event data quality - via (prototype) farm
- archive/display system - MonAlisa, other possibilities
- event display
- detector
- Alarm system
- design goals
- epics, LASER, cMsg/CLAS, A-B, others
- Misc
- networking
- databases - MySQL or PostgeSQL
- run and shift bookkeeping
- e-log - CLAS, CRL or other public domain, write one yet again, etc.
