Mechanical structure and housekeeping system for the FARCOS clusters

FARCOS (Femtoscope ARray for Correlation and Spectroscopy) is a novel modular detection system featuring high angular and energy resolution. It aims at reconstructing the particle's momentum at high precision and performing correlation measurements of LCPs and of LCPs and IMFs. The final system will be composed of 20 telescopes and the first prototypes will be ready to take data starting from 2017. A key point toward modularity and transportability is the module architecture together with its housekeeping system. The local housekeeping is based on the microcontroller housed on the patch panel and performs the following monitoring and control functions: i) monitor ASIC and board temperature, ii) provides input test signals according to a given pattern for system calibration, iii) sets all the ASIC control bits. A master microcontroller inside the vacuum chamber and communicating via IEEE 485 to the host PC oversees the system.
