18k Channels single photon counting readout circuit for hybrid pixel detector

“…There are many designs of small prototype integrated circuits, even in very advanced nano-CMOS technologies or 3D technologies [9][10][11][12]. However, for practical applications, large area integrated circuits play a crucial role, especially if they allow to build large area detector systems [5,13,14]. In such kinds of integrated circuits, critical parameters are a good uniformity of analog parameters for all channels, a low noise performance with a small power consumption per single pixel, no additional crosstalk, high count rate, etc.…”

TSV last for hybrid pixel detectors: Application to particle physics and imaging experiments

“…Thanks to this technology, the cost and the form factor of components could be decreased and the performance of the global system could be enhanced. In the field of radiation imaging detectors the advantages of 3D Integration come from reduced inter chip dead area even on large surfaces and from improved detector construction yield resulting from the use of single chip 4-side buttable tiles [2]. For many years, numerous R&D centres and companies have put a lot of effort into developing 3D integration technologies and today, some mature technologies are ready for prototyping and production [3].…”

Photon imaging using post-processed CMOS chips

“…In initial tests on single anode devices (not imaging chips) we observed good results with both Ar−CH 4 and Ne−CH 4 mixtures. ese devices are inherently spark proof.…”

“…is requires connections from the front side to the backside of the detector substrate as well as many other advanced technologies, for instance related to edge termination of the detector bias voltage. Examples of such a tiled detector can be found in [4].…”

“…Surface breakdown will be strongly suppressed in the Ne, Ar or He based gas mixtures typically used in the gaseous radiation detectors [36]. Speci cally the additional molecular gas fraction that is added to these mixtures, such as CH 4 , isobutane or DME, increase the breakdown strength greatly. erefore we have not investigated surface breakdown effects further.…”
