Visualization of radiotracers for SPECT imaging using a Timepix detector with a coded aperture
V. Rozhkov, G. Chelkov, I. Hernández +8
The work shows the ability to visualize radiotracers used in SPECT with a system based on a coded aperture mask and a hybrid pixel Timepix detector with the CdTe sensor. Characteri…
Properties of GaAs:Cr-based Timepix detectors
P. Smolyanskiy, G. Chelkov, S. Kotov +5
It is the hybrid pixel detector technology which brought to the X-ray imaging a low noise level at a high spatial resolution, thanks to the single photon counting. However, silicon…
Fast optimal decomposed modification of FDK with potential decreasing of memory consuming
Vladyslav Andriiashen, Danila Kozhevnikov
We present a new algorithm for 3D cone-beam tomography. The algorithm is based on decomposition of the cone-beam backprojection operation and angular decimation. It has computation…
Response of Timepix detector with GaAs:Cr and Si sensor to heavy ions
S. M. Abu Al Azm, G. Chelkov, D. Kozhevnikov +5
The response of the Timepix detector to neon ions with kinetic energy 77 and 158.4 MeV has been studied at the cyclotron U-400M of the JINR Flerov Laboratory of Nuclear Reaction. S…
Measurement of shower development and its Molière radius with a four-plane LumiCal test set-up
H. Abramowicz, A. Abusleme, K. Afanaciev +57
A prototype of a luminometer, designed for a future e+e- collider detector, and consisting at present of a four-plane module, was tested in the CERN PS accelerator T9 beam. The obj…
Measurement of the energy resolution and calibration of hybrid pixel detectors with GaAs:Cr sensor and Timepix readout chip
A. P. Butler, P. H. Butler, S. T. Bell +14
This paper describes an iterative method of per-pixel energy calibration of hybrid pixel detectors with GaAs:Cr sensor and Timepix readout chip. A convolution of precisely measured…
Alignment and resolution studies of a MARS scanner
A. P. Butler, P. H. Butler, S. T. Bell +9
The MARS scanner is designed for the x-ray spectroscopic study of samples with the aid of computer tomography methods. Computer tomography allows the reconstruction of slices of an…
Performance of fully instrumented detector planes of the forward calorimeter of a Linear Collider detector
The FCAL Collaboration, H. Abramowicz, A. Abusleme +66
Detector-plane prototypes of the very forward calorimetry of a future detector at an e+e- collider have been built and their performance was measured in an electron beam. The detec…
