1 CR7-FMD, 19 March 2007Jens Jørgen Gaardhøje, Niels Bohr Institute 1 Forward Multiplicity Detector FMD 1 FMD 3 FMD 2 Outer ring Inner ring

2 CR7-FMD, 19 March 2007Jens Jørgen Gaardhøje, Niels Bohr Institute 2 FMD3 Cone and Beam Pipe Support FMD3 support cone holds the beam pipe via 4 tensioned wires Test of final cone and wire mechanism: Deformations <10 um. Beampipe support

3 CR7-FMD, 19 March 2007Jens Jørgen Gaardhøje, Niels Bohr Institute 3 FMD2 support IP FMD2 support is a carbon fibre cylinder Mounting flap Honeycomb detector mounting plates Water cooling plate for FMD2 enclosure

4 CR7-FMD, 19 March 2007Jens Jørgen Gaardhøje, Niels Bohr Institute 4 Digitizer cards, 40Mhz bus, RCU, DAQ, Trigger Digitizer cards: 2 types: inner, outer 3 ALTROs + Board Controller 3 m bus cable to RCU gave many problems. Solved by changing from ALTRO flat bus to twisted pair cables. Trigger (LTU) tested DAQ operational. 40 bit signal + 10 grounds 40 bit signal + 40 grounds Twisted pairwise adaptor

5 CR7-FMD, 19 March 2007Jens Jørgen Gaardhøje, Niels Bohr Institute 5 Performance in beam 680 MeV e - beam test at ASTRID ring, Aarhus University, DK 3inner+3outer FMD modules (4608 channels) e - beam
