DAQ Status • Goal for BTF • Status • First results • To be done Jean-Sébastien Graulich
Goal for BTF • Stand alone, local DAQ • DAQ Reduced to minimum: Local Start/Stop of Runs (no remote Run Control -> no DAQ framework, no event building) Write data on local Disk Readout particle per particle No interrupts • VME-PCI interface: CAEN V2718 only • Limited number of FEE modules supported • TDC V1290 • QDC V972 • Only 2 Event types: • Particle Event • Calibration Event Jean-Sébastien Graulich
Status • Manpower: me and 1 undergraduate student • Software for V2718: 80% done • All fundamentals are done: Read and Write in A32/D32,D16 Read in BLT32, BLT64 Basic I/O Register (2 Inputs, 5 Outputs) • Software for V1290: 80% done • Only tested with V1190, should be easily transported to V1290 • Not fully commissioned yet • Software for V792: 40% done • Work in progress • Software for run control: 25% done • Working on User interface Jean-Sébastien Graulich
First results • Readout rate of V1190 • 27 Mbytes/sec in BLT64 -> 5 ms to read the full V1190 buffer memory (Readout of the tracker would require at least 40 Mbytes/sec… already obtained with BIT3 interface -> we might have to deal with 2 different interface. No impact for BTF) Jean-Sébastien Graulich
To be done • I need some inputs • Define needs for calibration • Define needs for online monitoring • Define needs for other FEE modules • Tests of QDC FEE options will start in background • Organize transport of my PC… • When is the test beam ? Jean-Sébastien Graulich
