CMS Sensormeeting : Probestation 1: 6“ (200mm * 300mm + 360° rotation + 15mm Z) Mechanical Assembly ready Instruments: LCR, Electrometer, PS, Quasistatic CVmeter Probestation 2: 4“ (100mm * 100mm + 15mm Z) (IQC) Working ( old software version )! improvements planned: increase of max. movement  200m stage ordered 4“  6“

CMS Sensormeeting : Vacuum Chucks  4 individual vaccum systems to cope with the different sensor geometries  Masks for all sensors types to cover free vacuum channels  Actual chuck has a leak in the cooling channel  good a RT  Bias supply travels with sensor  System to spill air onto COLD sensors  We will build 3 improved versions beginning January.  Actual: one „WARM“ Chuck + intermediate chuck present

CMS Sensormeeting :  New Software 95% ready.  Switching Devices (3 of 4) ready  16 channels for each station.  New framegrabber cards (Nat. Inst. PCI 1408) + IMAQ VISION software; programming underway.  Storage present: large old metal chemical cubboard ~ airtight, flooded with dry air.  Piping system ready to be installed (partly done) (vaccum, cooling liquid, dry air)  Chiller present  Precision Hygrometer ordered, evaluation object tested (next slide)  RH in probestation goes down to 0.4% at RT and 4% at –10°C

CMS Sensormeeting : Hygrometer First instrument (shown at last meeting) is not sufficient for our purpose:  Precision only „good“ at a certain temperature, linear correction is not enough:  Readout jams the system because it uses the system interrupts (works fine but slowly under DOS)  New system:  Controls up to 4 sensors  RH; T, Dew Point + others  RS232 bus: unidirectional ASCI transmission  possible to readout with many PCS.  High Precision at all temperatures (2D correction matrix)  We tested it from RT to –10°C  Drawback: CHF 2000.– for Control + CHF 450.– each Sensor (add.10% rebate)

CMS Sensormeeting : Experience from first Irradiation and cold measurements  Cyclotron run successful.  Cool box during irrad. OK – still room for improvements!  Chuck has to be improved – principle is ok.  First strip measurements with bricolage cooling chuck done.  Humidity under control.  Two additional cold boxes for IV and CV are under construction.  Oven for annealing installed.  Yesterday ( Dec 5): first test with biased structures during Irrad.
