Detection of scintillation light in noble gases with wavelength-shifting optical fibers
S. R. Soleti, S. Torelli, G. MartÃnez-Lema +110
Wavelength-shifting (WLS) techniques enable particle detectors based on noble gases, whose scintillation light is predominantly emitted in the vacuum-ultraviolet. We investigate WL…
Novel High-Radiopurity Doped Amorphous Silicon Resistors for Low-Background Detectors
A. Anker, P. C. Rowson, K. Skarpaas +9
We present the results of a study of lightly doped amorphous silicon used as a resistive medium for high-radiopurity resistors in nuclear and particle physics research instrumentat…
Design of a high voltage delivery system for noble liquid time projection chambers
R. Saldanha, L. Pagani, E. Angelico +129
Noble liquid time projection chambers (TPCs) are a leading technology in the detection of ionizing radiation, particularly in applications such as accelerator neutrino physics, dar…
Enhanced sensitivity to trace U impurity of sapphire via coincidence neutron activation analysis
D. Chernyak, I. J. Arnquist, T. Daniels +9
Sapphire has mechanical and electrical properties that are advantageous for the construction of internal components of radiation detectors such as time projection chambers and bolo…
Demonstration of Sub-Percent Energy Resolution in the NEXT-100 Detector
NEXT Collaboration, M. Pérez Maneiro, M. MartÃnez-Vara +111
NEXT-100 is a high-pressure xenon time projection chamber with electroluminescent amplification, designed to operate with up to approximately 70.5 kg at 13.5 bar. It is the most re…
First results of the NEXT-100 detector using Kr decays
NEXT Collaboration, G. MartÃnez-Lema, C. Hervés Carrete +113
The NEXT collaboration is investigating the double beta decay of Xe using high-pressure gas electroluminescent time projection chambers, which provide excellent energy reso…
