GaAs sensors

GaAs sensors are produced with 500 µm thickness. The high efficiency of the GaAs sensors allows the use for applications with X-ray energies from 15 keV up to 80 keV.

Medipix2 and Timepix detector modules with GaAs sensors are with 55 µm pixel size:

  • Single module kit with 65 K pixels and 2 sqcm active area

  • Hexa module with 390 K pixels and 12 sqcm active area

More details are available here.

The attached images show were recorded with single and Hexa modules  unsing GaAs sensors.
