Description
In collaboration between DESY MPY-1 and DESY FH ATLAS a silicon strip detector for the ARES spectrometer is being developed. This detector will be used for low (sub-pC) charged beams where a good spatial resolution is needed. It will be placed after the spectrometer dipole. The detector consists of two 1cm x 1cm silicon strip sensors. The readout is done by 4 charge-to-digital converters with three strips grouped together per readout channel. The key specifications of the ATLAS miniatures strip sensors developed for the HL-LH ATLAS tracker upgrade are a pitch of 74.5 micron, 103 strips per sensor and a thickness of 310 microns. Current-Voltage and Capacitance-voltage measurements were performed at the UNI HH lab. Measurement results and a dedicated charge production simulation tool will be presented and discussed in detail. A proof of principle experiment is foreseen at the DESY II test beam at the beginning of 2019.
