Minutes

Attendees: Elliott W, Beni Z, Dave A, Simon T, Hovanes E, Chris C, Mark I, Alex S, Dave L, Dmitry R, Bryan M, Graham H.

UPS

Elliott reported that Walt A is ordering the counting UPS using FY11 funds. Installation should start in Jan and be complete by Feb 2012.

Computer Storage

We will soon store all extra computer and related equipment in the Hall D trailer to free up space in F117 and EEL 126 for electronics testing.

Hall/Counting House Schedule

The current schedule gives us beneficial occupancy of the counting house around 1-Dec. There are rumors this may be delayed a month.

• Bryan Hess will install interim networking in the counting house and interim wireless in the hall.
• Magnet cooldown is expected to begin in Oct-2012.
• Elliott raised the question of if and when we need a computer system manager. Much discussion ensued. Some preferred a full-time Hall D employee, others preferred to matrix in someone from the IT division.

Simulated Raw Data File

Dave A gave an overview of information he needs to create a raw data file from MC data, see his note for details. Format is finalized for FADC250, not for FADC125, F1TDC32 nor F1TDC48. We suggested he just follow the FADC250 format for the the others for the interim. Elliott will supply all the information he asked for within the DANARAW framework.

Other DAQ Group Tasks

• Dave A gave an overview of how the event disentangler will fit into the overall CODA3 event building scheme (Carl is working on this).
• Generic Hall D disentangler possible because we only us standard DAQ modules and don't mix modules in a crate.
• Graham noted the DAQ group is planning to develop a more generic disentangler, but delivery is many years off, and we need ours at startup.
• Bryan is working on the automated readout list.
• Vardan is working on the "farm manager", but at a very high level so his work will be applicable to other similar Hall D controls components. Hovanes questioned the emphasis on farm management vs overall Experiment Control.

Multi-crate Trigger Test

Bryan reported that things are moving along well. He as achieved 160 kHz trigger rate (uniform trigger, not random). Ed has gotten the 2ESST transfer working (on FADC250?). The GBit serial lines are being tested now. And Hai is poised for a "breakthrough" in the FPGA programming.

Electronics

Chris reported that the first group of TI's and SD's are in.
