All modules tested using AERO

• Module(s) mounted in Liverpool Cooling Box
• Module(s) mounted  onto cooling block with thermal pad (electrically conductive).
• Agnd connection to box.
• Clip-on choke used on LV-3 power supply cable to module - 5m length.
• Optical (Electro-optical Emulation) data routes (Select = 0)

• Nominal ABCD bias settings (FEShp = 30uA, FEBias = 220uA)
• Nominal Vdet = 150V
• Thybrid ~13C

 

Results

Module:     M-O-042

• Front-end Input noise, Link0  = 1467e, Link1 = 1508e;
• Gain, Link0 = 54.03mV/fC, link1 = 53.97mV/fC;
• Threshold variation (for TrimRange 0) , Link0 = 2.7mV, Link1 = 2.08mV.
• Noise Occupancy, Link0 = 1.13x 10^-5 .Link1 = 1.09x 10^-5.

Conclusions

• Module has been demonstrated to operate successfully using both the Optical and Redundant data routes.
• There is little discernable difference with the module performance whichever method of module readout is selected.
