E-Detector Motion System

• The electron detector is connected to the QWAD using the custom made Flex-cable. The detector is placed inside the vacuum-can whereas the QWAD is placed outside using appropriate flanges used between the Flex-cable and the QWAD. The connection between e-detector and the QWAD (if the vacuum - can was transparent) can be depicted as in the attached picture.

• The electron detector vacuum - can has a motion mechanism to allow us to move the detector vertically in and out of the beam along with the ability to rotate the detector facing the beam. A schematic view of the assembly can be seen here.
