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.

We are using a stepping motor identified as KML062S04 for vertical motion ( data sheet ) of detector. This motor is being controlled by a single axis IDC Controller (User Manual)

Current Controller Settings:

Current: 1.5A

Resolution: 18000

Inductance: 16 mH

Direction: positive

Distance Unit: inch

Acceleration Unit: in/s^2
