Tangerine project - Studies of MAPS prototypes in CMOS 65 nm technology — •Gianpiero Vignola for the Tangerine collaboration — Deutsches Elektronen-Synchrotron, Hamburg, Germany

CMOS Monolithic Active Pixel Sensors, widely used as imaging devices, represent an attractive alternative to hybrid pixel detectors in High Energy Physics. The Tangerine project at DESY aims to develop a fully integrated 65 nm CMOS pixel sensor for future application, from beam-test facilities to Higgs factories. The goal is to achieve time resolutions of the order of 1 ns and spatial resolution below 3 µ m. First 65 nm CMOS test chips with 4 pixels of 16 µ m pitch and analog readout have been investigated in beam-test studies and with an Iron-55 source. Results of detailed waveform analysis, characterizing the charge sensitive amplifier, will be reported. The outcome of these studies will be used to improve the sensor layout and its signal-processing circuitry in the next Tangerine prototype.
