Since mid 2000s we have been following up development of Medipix detectors, as they were highly sensitive, could be used to detect photons, electrons and charged particles and could also measure the energy deposition on a micrometer/cellular level. Unfortunately at that stage the access to technology was limited and only available via collaboration with CERN. This situation however changed in 2012, when the technology was released to industry partners, including Amsterdam Scientific Instruments (ASI), the Netherlands. We have selected their Timepix device (development of Medipix) because of the removable detector cover which makes it suitable for detection of both photons and charged particles (e.g. alpha particles) and as a result it can be used both for imaging as well as dosimetry applications with mixed radiation fields. ASI have been excellent in discussing the apparatus and its performance, providing us with numerous literature, in addition to attractive quote. Once received, the apparatus and the data acquisition system were easy to assemble and we could proceed with measurements immediately.
We have enjoyed excellent collaboration and support by Amsterdam Scientific Instruments, who provided on-site as well as teleconference training and technical support. They have also provided us with software updates and other technical upgrades. We highly recommend ASI to other research institutions interested in the TIMEPIX detector.
