Detector installation
The Qweak GEM detector has been installed in the doghouce in Hall-C and the HV was turned on. On the scope picture below is shown the GEM trigger out pulse, after it has been amplified and integrated with timing filter amplifier. The high voltage supply is placed in the doghouse with the other electronics.
Electronics
We have the NIM Bin with the following modules: Leading edge discriminator, timing filter amplifier(X2), Gumstix module.
Gas
The gas bottle filled with ArCO2 is placed outside the doghouse. We have two 90 ft shielded twisted ribbon cables next to region 1 area.
