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…
Development of the CMS detector for the CERN LHC Run 3
CMS Collaboration
Since the initial data taking of the CERN LHC, the CMS experiment has undergone substantial upgrades and improvements. This paper discusses the CMS detector as it is configured for…
Pixelated silicon detector for radiation beam profile measurements
Joonas Tikkanen, Stefanie Kirschenmann, Nikita Kramarenko +6
A pixelated silicon detector, developed originally for particle physics experiments, was used for a beam profile measurement of a Co-60 irradiator in a water phantom. The beam prof…
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.…
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…
The upgrade of the ALICE TPC with GEMs and continuous readout
J. Adolfsson, M. Ahmed, S. Aiola +232
The upgrade of the ALICE TPC will allow the experiment to cope with the high interaction rates foreseen for the forthcoming Run 3 and Run 4 at the CERN LHC. In this article, we des…
Twin GEM-TPC Prototype (HGB4) Beam Test at GSI and Jyväskylä - a Development for the Super-FRS at FAIR
F. García, R. Turpeinen, J. Äystö +18
The FAIR[1] facility is an international accelerator centre for research with ion and antiproton beams. It is being built at Darmstadt, Germany as an extension to the current GSI r…
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…
