Hit-time and hit-position reconstruction in strips of plastic scintillators using multi-threshold readouts
N. G. Sharma, M. Silarski, J. Chhokar +32
In this article, a new method for the reconstruction of hit-position and hit-time of photons in long scintillator detectors is investigated. This research is motivated by the recen…
Estimating relationship between the Time Over Threshold and energy loss by photons in plastic scintillators used in the J-PET scanner
S. Sharma, J. Chhokar, C. Curceanu +36
Time-Over-Threshold (TOT) technique is being used widely due to its implications in developing the multi channel readouts mainly when fast signal processing is required. Using TOT…
Performance assessment of the 2 positronium imaging with the total-body PET scanners
P. Moskal, D. Kisielewska, Z. Bura +39
In living organisms the positron-electron annihilation (occurring during the PET imaging) proceeds in about 30% via creation of a metastable ortho-positronium atom. In the tissue,…
Feasibility studies of the polarization of photons beyond the optical wavelength regime with the J-PET detector
P. Moskal, N. Krawczyk, B. C. Hiesmayr +31
J-PET is a detector optimized for registration of photons from the electron-positron annihilation via plastic scintillators where photons interact predominantly via Compton scatter…
A feasibility study of the time reversal violation test based on polarization of annihilation photons from the decay of ortho-Positronium with the J-PET detector
J. Raj, A. Gajos, C. Curceanu +31
The Jagiellonian Positron Emission Tomograph (J-PET) is a novel de- vice being developed at Jagiellonian University in Krakow, Poland based on or- ganic scintillators. J-PET is an…
Time resolution of the plastic scintillator strips with matrix photomultiplier readout for J-PET tomograph
P. Moskal, O. Rundel, D. Alfs +27
Recent tests of a single module of the Jagiellonian Positron Emission Tomography system (J-PET) consisting of 30 cm long plastic scintillator strips have proven its applicability f…
Searches for discrete symmetries violation in ortho-positronium decay using the J-PET detector
D. Kamińska, T. Bednarski, P. Białas +24
In this paper we present prospects for using the J-PET detector to search for discrete symmetries violations in a purely leptonic system of the positronium atom. We discuss tests o…
Reconstruction of hit-time and hit-position of annihilation quanta in the J-PET detector using the Mahalanobis distance
N. G. Sharma, M. Silarski, T. Bednarski +24
The J-PET detector being developed at Jagiellonian University, is a Positron Emission Tomograph composed of the long strips of polymer scintillators. At the same time it is a detec…
PALS investigations of free volumes thermal expansion of J-PET plastic scintillator synthesized in polystyrene matrix
A. Wieczorek, B. Zgardzińska, B. Jasińska +25
The polystyrene dopped with 2,5-diphenyloxazole as a primary fluor and 2-(4-styrylphenyl)benzoxazole as a wavelength shifter, prepared as a plastic scintillator was investigated us…
Processing optimization with parallel computing for the J-PET tomography scanner
W. Krzemień, M. Bała, T. Bednarski +27
The Jagiellonian-PET (J-PET) collaboration is developing a prototype TOF-PET detector based on long polymer scintillators. This novel approach exploits the excellent time propertie…
