1. JLAB discriminator
Ben made a big progress on discriminator design, it is almost ready for prototype building with following features:
- price estimate: components about $1600/board+$200/pcb and assembly+front pannel = $2000 maximum -> $125/channel
- need about $7000 for 2 prototypes, will use ops money
- in about 1-1.5 month can expect sample board
2. Work for downtime
- SY1527 HV connectors problems
- clon cluster OS upgrade
- FASTBUS power supply replacement continues
- FASTBUS boards testing in test setup
- CODA improvements (EB recovers, ROC crashes)
