Journal ArticleDOI
The Medipix3RX: a high resolution, zero dead-time pixel detector readout chip allowing spectroscopic imaging
Rafael Ballabriga,J. Alozy,Gabriel Blaj,Michael Campbell,Michael Fiederle,Erik Fröjdh,Erik H.M. Heijne,X. Llopart,M. Pichotka,S. Procz,Lukas Tlustos,W. Wong +11 more
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
3D track reconstruction capability of a silicon hybrid active pixel detector
Benedikt Bergmann,M. Pichotka,Stanislav Pospisil,Jiri Vycpalek,Petr Burian,Petr Burian,P. Broulím,P. Broulím,Jan Jakubek +8 more
TL;DR: In this article, the drift time information can be used for particle tracking, with the three spatial dimensions and the energy losses along the particle trajectory (dE/dx), where the coordinates in the detector plane are given by the pixelation (x,y).
Journal ArticleDOI
Spectral CT data acquisition with Medipix3.1
Michael F. Walsh,S J Nik,S. Procz,M. Pichotka,Stephen T. Bell,C.J. Bateman,R. Doesburg,N. J. A. de Ruiter,Alexander I. Chernoglazov,Raj K. Panta,Anthony Butler,Philip H Butler,Philip H Butler +12 more
TL;DR: In this article, the authors describe the acquisition of spectral CT images using the Medipix3.1 in spectroscopic mode, in which the chip combines 2 × 2 pixel clusters to increase the number of energy thresholds and counters from 2 to 8.
Journal ArticleDOI
Measurement of particle directions in low earth orbit with a Timepix
St. Gohl,Benedikt Bergmann,Carlos Granja,Alan Owens,M. Pichotka,Stepan Polansky,Stanislav Pospisil +6 more
TL;DR: In this paper, the authors used a Timepix detector attached to the Proba-V, an earth observing satellite of the European Space Agency (ESA), to determine the directions of energetic charged particles and their corresponding stopping powers.
Journal ArticleDOI
Dual energy CT inspection of a carbon fibre reinforced plastic composite combined with metal components
TL;DR: In this paper, the dual energy computed tomography (DECT) was used to analyze honeycomb sandwich panels and carbon fiber reinforced plastic composites (CFRP) joined with metal fasteners.
