Design of the new testboard for the SPIROC2e BGA package — •Amine Elkhalii for the CALICE-D collaboration — Wuppertal University

The CALICE Collaboration is developing calorimeters for a future e⁺e⁻ linear collider. These calorimeters have a high granularity in order to allow Particle Flow Analysis and to achieve a jet energy resolution of 3-4%. One of these concepts is the Analog Hadronic Calorimeter (AHCAL) based on 3×3×0.3 cm³ scintillator tiles with individual Silicon Photo-multiplier (SiPM) readout. A former physics prototype of the AHCAL has proven the performance and suitably of a such concept. The current focus of the second generation engineering prototype is to have a 1m³ detector, which is fully scalable to a linear collider detector with all its constraints. A huge amount of components have therefore to be tested before assembly, including the SPIROC ASIC developed by Omega. This chip provides the readout for 36 SiPMs, including individual bias voltages, self-triggering, timing measurements and 12-bit signal resolution, while maintaining a very low power consumption of 25 µW per channel. Around 1000 of these ASICs have to be characterised and tested for the prototype in 2017. This talk will focus on the development of the test stand and the first results on the testing and characterisation of the chips.
