Design and development of the muon detector housing system

RINA-CSM and INFN have worked on the design and implementation of a muon detector housing system to protect the detector from dust and mechanical shocks. This system must also guarantee the tilting of the detector in order to change its elevation angle. It is foreseen that the instrument can be oriented both towards the blast furnace wall but also in the direction of the free sky during the calibration phase.
It consists of two main blocks. An outer box and an inner box. The outer box has the function of providing a robust rigid structure suitable for its movement with a forklift. On the outer box are located the chiller (exposed to the air), the external electronics, and the inner box (protected by thermal panels) with its tilting system.
The inner box houses the muon tracking modules, the detector electronics, fans, and radiators for cooling. The inner module is able to rotate with respect to the horizontal axis by changing the elevation angle of the tracking planes. The tilting is carried out using an electric motor positioned below the inner box.
