Latest revision as of 10:04, 4 May 2022
- Updates
- HCAL
- Bryan booted the VTPs and working on readout list for VTP
- Ben 10 gigE transceiver, Alexandre plugged the fibers to router
- VTP library and initial readout list setup, few configurations files need to be updated, switch to add to the flash readout list, maybe test in a few days
- Hodoscope
- Glasgow people coming in summer
- might still need to take data for ToT calibration with FADC
- GEM
- one layer taken out from BB, will replace HV parallel power supply
- can other detector be turned on ? HV GEM off so can take cosmics
- Shower : get ready to take cosmics again
- made configuration without GEM with 2 and 3 event builders
- HV
- HV software working with RPi4
- HCAL
- Discussion multiple streams
- testing DAQ setup https://logbooks.jlab.org/entry/3992794
- want to add second DC
- online monitoring
- EPICS/scaler insertion : would like to insert in all the streams ? Right now only going in one stream - ev
- 3 streams : 3 to 1 split - evenly
- open 3 files at same time - and make one stream ? ( need software work )
- or put back 3 streams in one and feed existing software
- Helicity info insertion - Paul has readout list to test with ring buffer
- if in time can record in register -
- new helicity board should be avalaible : can record helicity event by event
- use the scaler and event register
- needs helicity event ?
- only one stream of event number - unique
- Ole could try to open 3 streams and produce one stream - small snag : number of event could be different
- input class taking all segments to present to analyzer , so could adapt class for multiple streams
- charge feedback ? with multistream - use parity DAQ so most likely ok- could use scalers but less precise - Could set up QWeak - Parity DAQ using CODA 2.6 - ET would be broken for CODA 3 - but existing should be fine for feedback
- Helicity info insertion - Paul has readout list to test with ring buffer
- software required changes to handle multiple stream files
- make sure some headers are in all stream : control events written to all 3 streams
- feature used by Hall D, every time new split file , one event can be recorded in each new BOR
- can write to one stream by selecting the ET system where EB runs
- Channel counts for GEM per plan : Alex will get ( from Kondo presention )
- GEn ERR : option to have GEM SBS was not on ERR - 20 or 30 lower luminosity
- GEn RP : had all the GEMs -
