ATLAS IL 2011 Happy New Year SLHC Meir Shoa
ATLAS IL 2011 • New detector. • Test beam at Cern.
NEW DETECTOR Pads board Strip board New pads technology Pads nearest to graphite. 100 micron New way to connection Closer ground to the pads. 1.6mm Strip cutted in2 Length 60 cm
NEW DETECTOR New graphite machine More homogenic resistivity Direction of spray according to the wires Read out connections Half chamber
NEW DETECTOR Wires read out Pads read out Strip read out
Read out connections WIRES PADS STRIPS
Tech. GAS SYSTEM We used this gas system for the testbeam and it works very well till the last day . In the last day the gas system stopped working and We had to use an old fashion gas system. We brought the gas system to Israel to repair.
Readout setup New quadruplet MDT Old quadruplet KEK BUFFERS Logic units VME units VME read out HV system
TEST BEAM • We had Beam for about 14 days • We had more then 200 runs 30 of them combined with MDT • We used 2 read out systems ( VME and CMS) • We take data from 350 channels. • Results will be shown by Nachman and Yonathan.
Conclusion • We had a very good Test at CERN using the new Detector. ( much better then the old one.) • We got very good results that will be shown by Yonathan and Nachman. • We had some small problems with the gas system and with the TDC.
