Ingrid-Maria Gregor, DESY Infrastructure DESY Summary Fourletova, Tobias Haas Ingrid-Maria Gregor, Julia Fourletova Tatsiana Klimkovich, Ulrich Koetz Alessandro Montanari, Carsten Muhl, Jolanta Sztuk Ø Chip Characterisation Ø Integration Planning JRA 1 Meeting in Geneva March 27 th 2007

Ingrid-Maria Gregor, DESY Infrastructure Board Testing Ø First bonded Mimo. Tel and Mimosa 18 were delivered to DESY Ø Along with this we received new versions of Strasbourg DAQ and JTAG programming Ø Turning on the Mimo. Tel and Mimosa 18 was without any problems Ø Ø Preparing a test protocol to have a standardised test procedure for each sensor of one kind Ø Functionality test (smoke test ; -) ) Ø Pedestal and noise Ø Response to Fe 55 Ka and Kb Ø Number of dead/noisy pixel Ø Anything else ? Store all information on data base accessible for JRA 1 members Ø Results, “features” Ø location

Ingrid-Maria Gregor, DESY Infrastructure Noise distribution Pedestal distribution Mimo. Tel (20 mm) Ø Example: chip#3 on Strasbourg sensor board Ø Data taken at 10 MHz Ø Noise: ~4. 5 ADC -> 25 e- Ø Wojtek: only 16 e- noise Ø Observed rise in noise when taking data -> sensitive to temperature increase Ø Textbox is noticeably warm Ø Systematic studies will start next week when test box is cooled (and temp. stabilised)

Ingrid-Maria Gregor, DESY Infrastructure Mimo. Tel (20 mm)

Ingrid-Maria Gregor, DESY Infrastructure Mimo. Tel (20 mm) Ø Fe 55 signal Ø Kb peak lost in noise

Ingrid-Maria Gregor, DESY Infrastructure Mimo. Tel (14 mm) Ø Connected to exactly the same AUX board with same settings and same file for JTAG programming Ø Noise already quite decreased Ø Need to study in detail Ø Fe 55 signal Ø Kb visible

Ingrid-Maria Gregor, DESY Infrastructure Mimo. Tel (14 mm) - Hitmap Ø Example: chip#20 Ø Data taken at 10 MHz Ø Noise: ~3. 6 ADC -> <20 e- Ø Pixels with >150 hits = red

Ingrid-Maria Gregor, DESY Infrastructure Mimosa 18 Noise distribution Pedestal distribution Ø Test of Mimosa 18 was very straight forward Ø First noise measurement showed similar results as Wojtek (11 e-)

Ingrid-Maria Gregor, DESY Infrastructure Senor Boxes Ø Mechanics design almost completed Ø 3 planes on one main structure Ø Each has different geometry depending on position Ø Each plane movable individually with small tool Ø Minimal distance between planes: 7 mm Ø Maximum level arm: 200 mm Ø Material: aluminum Ø All material non-magnetic Ø Materials were optimised for minimal thermal stress Carsten Muhl

Ingrid-Maria Gregor, DESY Infrastructure Overall Construction Box 1 Box 2 y x z Box 3 (DUT) Ø Design now finalised Ø Machining will start next week Ø Complete system available end of June Carsten Muhl

Ingrid-Maria Gregor, DESY Infrastructure Overall Integration Ø Mechanics completed by end of June Ø May/June 2007 Ø first test of 2 (or more) chips in testbeam at DESY Ø Ample of time booked for area 24 Ø EUDRB(s) at DESY necessary Ø July: complete assembly of mechanics + chips + readout (no test beams available at DESY 2. 7 -15. 8) Ø August: first test of complete system in testbeam Ø End of September: go to CERN for testbeam
