April 10, 2019 online meeting minutes
present: Sergey Boyarinov, vpk, Nathan, Eugene, Stepan,Ben, Rafo
1. RG-A status
- no TI "more then 7 words" errors during last 2 weeks, will try to reproduce it on high event rate after the run
- hallbcam08 needs occasional blip/recycle, may buy new camera (see below), Nathan will decide what to do
- hardware helicity correction board will be ready soon, also doing level3 correction and will do it offline
- few spare boards still needed (some jlab-made custom boards)
- HV mainframes hardware resets will be implemented (Ben, Nathan, Armen)
- for next few years DAQ/Trigger performance is good enough; trigger can be improved with multi prone tracks and neutral trigger; future can be with free running (streaming) daq
2. Equipment purchase list
- new 4-head desktops for counting room with TV 4K support (4 times more powerful)
- 2 big tv screen for counting room
- new fileserver for counting room
- replacement for bethsw network switches in the hall, other network equipment (media converters, network cards etc)
- desktops in the hall ?
- VME CPUs to replace older ones
- two new whiteboards or a big one (Mauri) - Stepan will look at that
- replace furniture that has the magnets computers to match the remaining stuff (Mauri)
- add pantry for the food. Very unprofessional on the table (Mauri)
- VTP ?
- climate control sensors
3. HPS preparations
- DAQ test setup is operational in SLAC, Ryan installed SVT readout prototype communicating to TIpcie card, 2 crate setup is running, both SVT readout lists are ready, 50kHz test was successful, working on finalizing data format; data so far is emulation, no real SVT connected yet
- no FADC compression (FDAC estimated as 30%, not much gain from it)
- trigger: GTP->VTP transition finished, hodoscope is in progress; in about 2 weeks Ben will be done with first trigger revision; in a meanwhile we'll discuss needed triggers more detaily (Stepan, Valery, Kail - montecarlo simulation
- Rafo preparing 2 PMT with scintillators, will be used to test trigger - end of April/ beginning of May
- SLAC will ship everything beginning of May
- need 2 more FADC for hodoscope, restore some scalers etc
