Detectors


Operating Conditions

Vcc   3.5V (on support card)
Vdd   4.0V (on support card)
Vdet   100V (660nA at 22.5C)

Bias Current  267 microA
Shaper Current  30 microA
Compression mode 1 (CENTRAL BIN, X1X)
Edge Detect  0 (OFF)

The module is mounted inside a QMW module box.  The box is connected to analogue ground at the patch card by means of a wire; the box is fitted with plastic covers.  No conductive rubber sheeting is placed inside the module box to ensure thermal contact between the cooled facing and the aluminum support: direct contact was found to be sufficient.  Basic cooling of the box is provided by means of a heatsink upon which it is placed (a large granite block) and a simple fan.


Trimming

Module trimmed such that 12.5 mV VCAL (guesstimate 1fC) = 120 mV
This gives a total of 51 untrimmable channels.

    Footnote

    The results given here refer to lab measurements made before the recent 40MHz testbeam run.  The module was retrimmed and recalibrated in situ at the beamtest, hence the calibration and operating conditions may differ in detail with respect to the testbeam results.
