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
Modified compensation model of CdTe
Michael Fiederle,C. Eiche,M. Salk,R. Schwarz,Klaus-Werner Benz,W. Stadler,D. M. Hofmann,Bruno K. Meyer +7 more
TL;DR: In this paper, a new compensation model based on a deep intrinsic donor level is presented, which is used together with an appropriate segregation model to calculate axial distributions of resistivity which are compared with spatially resolved resistivity measurements.
Journal ArticleDOI
Imaging properties of small-pixel spectroscopic x-ray detectors based on cadmium telluride sensors
T Koenig,Julia Schulze,Marcus Zuber,Kristian Rink,J.S. Butzer,E. Hamann,E. Hamann,Angelica Cecilia,Angelica Cecilia,A. Zwerger,Alex Fauler,Michael Fiederle,Uwe Oelfke +12 more
TL;DR: The imaging properties of Medipix2 MXR multi-chip assemblies bump bonded to 1 mm thick CdTe sensors are described and the finding that higher maximum count rates come at the cost of a reduced energy resolution is concluded.
Journal ArticleDOI
Charge Summing in Spectroscopic X-Ray Detectors With High-Z Sensors
T Koenig,E. Hamann,S. Procz,Rafael Ballabriga,Angelica Cecilia,Marcus Zuber,Xavier Llopart,Michael Campbell,Alex Fauler,Tilo Baumbach,Michael Fiederle +10 more
TL;DR: In this article, the Medipix3RX ASIC features a network of charge summing circuits establishing a communication between pixels which helps to mitigate the effects of charge sharing between neighboring pixels and the emission of characteristic X-rays.
Journal ArticleDOI
State of the art of (Cd,Zn)Te as gamma detector
TL;DR: In this article, (Cd,Zn)Te and CdTe were compared by their material properties and the compensation mechanism of (Cc,Zns)Te was compared to CcTe.
