Before installation in the vacuum vessel, the module support will be temporary mounted to the Detector Hood with left and right temp supports. While the module support is mounted to the detector hood, the cables will be inserted and modules were placed and measured. Just before installation these temporary mounts will be dismounted and the module support is laying by gravity on three pins. When it's installed the final position will be defined by the 3 bearings (defines the Y-Z position) and three surfaces (defines the angles and X position) at the stainless steel Detector Support.

The aluminum module support will be temperature controlled by 4 groups of heaters (total=24) and a couple of temperature sensors (PT100) which are glued to the inside of the module support. The CO2 cooling evaporator is flexible connected to this module support to allow expansion and shrinking due to temperature differences.
