Noise tests with MIMOSA-26 are ongoing. However, preliminary results concerning the influence
of the clamping voltage suggest that it is beneficial to generate this reference voltage as
close to the sensor as possible and to use decoupling capacitors, if possible, next to the

The sensors are now operated on a small copper platform which is cooled with a peltier element.
A PID controller implemented on a microcontroller senses the temperature of the platform by means of a onewire temperature
sensor and regulates the current through the peltier element. The device features a small display and a
Overall, the set-up was greatly reduced in size, while at the same time improved in usability.

For now, MIMOSA-26 sensors are used in this project though they do not qualify to be used in the final detector.
Parts of the front-end electronics are currently redesigned to fit the spacial constraints of the set-up.
