October 9, 2013 online meeting minutes

present: Sergey Boyarinov, Eugene Pasyuk, Vladimir Popov, Nerses, Ben

1. Test setups: Vladimir described PMT dividers for CTOF and HTCC; for CTOF it stabilizes voltage and improves timing resolution; for HTCC single-electron peak selection was improved; CTOF divider provides one signal, HTCC divider provides 2 signals (both negative from anode); for testing we will use diode with defuser do decrease light output and trigger daq from it; place for test setup to be defined - CTOF area or TEDF area; Vladimir will let us know when he is ready - we need money to finish project - waiting for USA budget; FADC range will be 1 Volt; expected HTCC threshold in CLAs12 is about 5 p.e.

2. DCRB trigger development:getting ready; Sergey made readout list to readout GTP over tcpvmeclient (C++), tested as dummy, works fine; Ben is finishing GTP firmware;measuring efficiency with scintillator trigger will be highest priority; Ben may need another week or so

3. Hall D will use css-beast for alarm tree, we'll discuss our plans with Ken in the end of October

4. Forward Carriage work started, will use v1495-baset trigger; JLAB DSC2s need new firmware, will set address jumpers to zero so they pick addresses from slot number; still have to decide how to read scalers from DSC2s, FADCs, DCRBs etc
