In-time efficiency of the MuPixel matrix - detection of the signals above 1000e is possible with the time resolution better than 40ns.

MuPixel1-3

We have designed so far three sensor prototypes for the Mu3e experiment (at PSI) in AMS 180nm HV-technology. We have proposed the following relatively conservative structure: The sensor pixels contain only charge sensitive amplifiers. The amplifier output signals are transferred to the mostly-digital readout cells at the chip periphery. The layout area of one readout cell is by factor of 20 smaller than the pixel area (80 x 80 micrometers).

Results

The chips MuPixel1 and 2 have been successfully tested. The detection of the particle signals is possible with very good time resolution (better than 40ns). A larger prototype - MuPixel3 is in the production.
