- The electron detector system is described in the figured below. The DAQ setup can be found on the Qweak wiki at [Qweak electron detector setup].
- The electron detector is moved in and out of the beam by the motion system showed below:
- The electron detector is composed of four 2.1cmx2.1cm planes separated by 1cm and staggered 100 µm with respect to each other. Each plane contains 96 horizontal diamond strips (polycrystalline CVD diamond). Each strip is 180 µm wide and they are separated by a 20 µm gap. Metalization was done on each plane with Titanium-Platinum-Gold (TiPtAu). The carrier boards are in Ceramic (alumina).
One edge of the detector is placed 0.5 cm from the primary beam and the location is 4 in front of the 4th dipole.
