Description
The increasing radiation levels in the ATLAS experiment and hence the radiation dose seen by the personnel during maintenance poses a new challenge to the design of components within highly radiated areas. During opening scenarios and the removal of chambers, the ATLAS VT Sliding Support, among other supports, must be retracted manually by the means of turning threaded bars which are connected to a triangular support system. Limited by the space constraints a possible solution to remotely retract the supports was found in the installation of radiation resistant stepper motors. Once installed these compact motors will allow the movement of the supports without any human intervention in the radiated areas. A design study for the mechanical design was performed and a suitable manufacturer was found. The new system shall be installed in 2014 to ensure that during the higher radiation levels in LS2 this task can be performed remotely.
