Status of the CALICE AHCAL Engineering prototype — •Brianne Eldwan for the CALICE-D collaboration — DESY
In the CALICE Collaboration are developed calorimeters for a future e+e− Linear Collider. One approach is called Particle Flow which requires highly granular calorimeters thus to achieve a jet energy resolution of 3-4%. The CALICE Collaboration is developing concepts and prototypes for Particle Flow optimized calorimeters with various readout technologies. The Analog Hadronic Calorimeter (AHCAL) is one of the concepts based on 3 × 3 cm2 scintillator tiles with Silicon Photomultipliers. The performance and suitability has been proven in the former physics prototype. The current focus of the second generation engineering prototype is on the full scalability of the detector. In 2014, two test beam periods happened at the PS at CERN, with an iron stack structure designed for the final detector (1 m3) and 15 active layers (including 3 ScECAL layers). This talk will focus on the engineering prototype commissioning phase before testbeam, the monitoring of the calorimeter during data taking and a first look into the data taken at the PS.
