Features

• 12 x ABCD3T, VDC, DORIC4A
• Module has been tested using the Redundant Clock/Command inputs with Spydata outputs and Pseudo-Opto readout.
• Module mounted on 'new' Liverpool cooling frame within a Faraday cage.
• There are 3 'screened fan-ins' on this module. These are located at chip locations: M0, S1, S2, M8, S9, S10, S11, S12, E13.

Module Configuration

• All data taken with Edge Detect Off and data compression set to mode 1 (X1X).
• FEBias = 220uA    FEShape = 30uA.
• VDD = 4.0V          VCC = 3.5V
• Data taken with module trimmed at 2.0fC.
• Module Temperature 45C
• Tests have been done with chips bonded to fan-ins only, this is done to test for any instability that might be present on a bare hybrid.

Tests and Results

• The module response (Computed from the Three Point Gain Macro), can be found here.
• Noise Occupancy for the the hybrid. There is a shoulder on link1 due to their being a 'hot' channel which cannot be masked. This can be seen in the Link1 Scurves (Chip5 Cal0).
• Noise Occupancy Scurves:  Link0 and Link1

The results show that a 'bare' K4 hybrid does not show any instability. The next step is to bond the top and bottom first 2 wedge detectors (approx 6cm length) to the readout and then repeat the measurements and test for instabilities that might arise due to the loading of the amplifiers.
