1. G12 run finally have new v1495-based level1 trigger commissioned, it is running at 8kHz with 12% deadtime and 35MB/s data rate. Level2 is used as well. DAQ looks stable. EPICS histograms for new trigger system were reportedly implemented by Nerses, we'll activate them shortly.
New Scintillator Hodoscope ADCs, TDCs and discriminators were connected and programmed, still need to finisg scalers wiring. Data need to be analysed to make sure everything connected properly. Discriminators control is in 'dimanv', Sergey P. will send to Stepan short instruction howto use it.
