Abstract :
A new generation of semi-conducting pixel sensors for detecting minimum ionising particles (m.i.p.) was designed and first prototypes of Monolithic Active Pixel Sensors (MAPS), called MIMOSA,22Standing for Minimum Ionising MOS Active pixel sensor.
fabricated in a standard CMOS technology. The performances of the first prototypes were evaluated with high energy π− beams and with an X-ray source in strong magnetic fields. The beam test results demonstrate that the sensors detect m.i.p.s with very high efficiency and signal-to-noise ratio and provide excellent spatial resolution. The influence of strong magnetic fields is observed to be modest.
