Description

The CALICE collaboration has constructed a hadron calorimeter prototype based on the SiPM-on-tile read-out technology. The scintillator-steel sandwich structure has 38 active layers consisting of 30x30x3mm3 tiles and has 22’000 channels in total. The read-out electronics - including zero-suppression, front-end memory buffering and digitisation of energy and time measurements - and the LED calibration system are fully embedded in the active layers, and the SiPMs are surface-mounted on the electronics boards. The detector is operated with cycled power supply and SiPM bias voltage adapted to temperature variations. The design and the production and quality assurance procedures are scalable to a full collider detector system. We report on the construction, commissioning and first test beam exposure of the prototype.
