  1. Micromegas TPC test in a high intensity beam D. Attié, P. Colas, M. Dixit, M. Riallot, W. Wang LC-TPC Phone meeting 109 Astrophysics Detector Workshop – Nice – November 18th, 2008

  2. Data taking diagram Goliath magnet Beam trigger Vdrift =1 kV CAEN 471A (NIM) SHV cables Vmesh = 380 V T2K electronics 1728 channels Back-end electronic (ML405) Optical fibre Lemo LV-TTL TCP/IP via ethenet LV (+5 V) PC T2K DAQ on Linux T2K gas (5L/h) 500 Go Standard PC Power supply HDD Hall Control room RD51 Mini-week, CERN – WG7 – February 24, 2010

  3. Detector description 1/2 1726 pads Micromegas resistive Kapton bulk 17 cm 23 cm 24 rows x 72 columns; <pad size> ~ 3.2x7 mm2 RD51 Mini-week, CERN – WG7 – February 24, 2010

  4. Detector description 2/2 • Total weight: ~20 kg • Radiation length: 40% (2×1.8 cm of aluminium) B field Top 27 cm 40 cm Bottom 35cm 11 cm RD51 Mini-week, CERN – WG7 – February 24, 2010

  5. Beam test at CERN (RD51, H4 beam) • Data were taken with muons mostly at 1 kHz and with hadrons at intensities up to 180 kHz (over a 5 cm x 1cm region) and 150 GeV energy. • The drift length was 28.8 mm and the field 240 V/cm • The gas was T2K • The mesh voltage was 380 V, which corresponds to a gas gain of 2500 • The detector peformed perfectly normally, as usual • We also tested a new, faster and multimodule DAQ. We obtained read-out rates of 40 Hz. RD51 Mini-week, CERN – WG7 – February 24, 2010
