Journal ArticleDOI

Timepix, a 65k programmable pixel readout chip for arrival time, energy and/or photon counting measurements

TL;DR: In this paper, the authors proposed a novel approach for the readout of a TPC at the future linear collider is to use a CMOS pixel detector combined with some kind of gas gain grid.
Journal ArticleDOI

The Medipix3 Prototype, a Pixel Readout Chip Working in Single Photon Counting Mode with Improved Spectrometric Performance

TL;DR: In this article, a pixel detector readout chip was developed with a new front-end architecture aimed at eliminating the spectral distortion produced by charge diffusion in highly segmented semiconductor detectors.
Journal ArticleDOI

The Medipix3RX: a high resolution, zero dead-time pixel detector readout chip allowing spectroscopic imaging

TL;DR: The Medipix3RX chip as mentioned in this paper uses an architecture in which adjacent pixels communicate in the analog and digital domains on an event-by-event basis to reconstruct the deposited charge in a neighbourhood prior to the assignation of the hit to a single pixel.
Journal ArticleDOI

Medipix3: A 64 k pixel detector readout chip working in single photon counting mode with improved spectrometric performance

TL;DR: The Dosepix readout chip as mentioned in this paper is a hybrid pixel detector for photon dosimetry, which consists of 256 square pixels of 220 mm side-length, constituting 12.4 mm2 of photo-sensitive area per detector.
