Evaluation of CZT Detector Performance in Alpha and Gamma Spectrometry
N. Kramarenko, M. Väänänen, M. Kalliokoski +3
Presented is a work on the performance studies of Cadmium Zinc Telluride (CZT) planar detector structures. Current-voltage (IV), capacitance-voltage (CV), and gamma- and alpha-spec…
Defect detection and size classification in CdTe samples in 3D
M. Väänänen, M. Kalliokoski, R. Turpeinen +4
Defects in semiconductor crystals can have significant detrimental effects on their performance as radiation detectors. Defects cause charge trapping and recombination, leading to…
Quality assessment of Cadmium Telluride as a detector material for multispectral medical imaging
S. Kirschenmann, M. Bezak, S. Bharthuar +12
Cadmium Telluride (CdTe) is a high-Z material with excellent photon radiation absorption properties, making it a promising material to include in radiation detection technologies.…
Employing infrared microscopy (IRM) in combination with a pre-trained neural network to visualise and analyse the defect distribution in Cadmium Telluride crystals
S. Kirschenmann, S. Bharthuar, E. Brücken +6
While Cadmium Telluride (CdTe) excels in terms of photon radiation absorption properties and outperforms silicon (Si) in this respect, the crystal growth, characterization and proc…
Hole Misalignment and Gain Performance of Gaseous Electron Multipliers
Erik Brücken, Jouni Heino, Timo Hildén +4
It is well known and has been shown that the gain performance of Gaseous Electron Multipliers (GEM) depends on the size of the holes. With an optical scanner it is possible to meas…
Optical quality assurance of GEM foils
T. Hildén, E. Brücken, J. Heino +5
An analysis software was developed for the high aspect ratio optical scanning system in the Detec- tor Laboratory of the University of Helsinki and the Helsinki Institute of Physic…
Preliminary Results of the CASCADE Hidden Sector Photon Search
Nathan Woollett, Ian Bailey, Graeme Burt +10
Light shining through a wall experiments can be used to make measurements of photon-WISP couplings. The first stage of the CASCADE experiment at the Cockcroft Institute of Accelera…
Tests of a Roman Pot Prototype for the TOTEM Experiment
M. Deile
The TOTEM collaboration has developed and tested the first prototype of its Roman Pots to be operated in the LHC. TOTEM Roman Pots contain stacks of 10 silicon detectors with strip…
