Electronics
Fernando gave a brief update on the status of the FADC125 and other boards:
- Bare board ready, mezzanine design done, 15 FPGA's total.
- Expect final cost approx $4k for 72 channel module.
- Has 3 x 24 channel connectors.
- Will have 3 ready by 1-Oct - one for JLab, one for CMU, one for IUCF.
- Production testing perhaps at IUCF, not sure yet.
- Dave A will produce readout libraries, about 6 weeks after he receives a board.
- Expect solid board and lib by end of 2009.
- About 70 Watts/board, similar to FADC250.
- F1TDC v2 and FADC250 v2 planned for FY10, redesigns starting now. These are production boards for Hall D.
- Two types of F1TDC inputs: ECL and LVDS, depending on front-end plug-in module.
Chris summarized some additional work:
- Trigger workshop went well, see notes and summary on Wiki.
- Got new requirements at workshop, esp for FADC250.
- Will hold again next year.
- Firmware changes for all boards not simple, takes planning and time. Cannot do this too often.
- Global trigger boards planned for FY10 (GTP, TS, etc.).
- New hires in Electronics and DAQ groups coming soon.
Coil Tests
- Elliott is developing schedules and manpower estimates.
- We need more than one Mark Stevens if we have to share him with the FDC effort.
- May need to get more high-class technician manpower.
- PR for Allen-Bradley controls components is in and signed, buyer assigned, shouldn't take too long to place the order.
Java EVIO
Graham and Elliott summarized recent progress on a Java version of EVIO, the online event I/O package used by CODA.
- A few people wrote basic I/O utilities for Java.
- Dave Heddle (CLAS12) working on duplicating full C++ EVIO tree package in Java.
- DAQ group will likely take over Dave's package and support it for all halls.
