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…
Electroluminescence Yield Measurements in Xenon Gas with the NEXT-DEMO++ Detector
NEXT Collaboration, J. Renner, J. D. Villamil +111
The NEXT-DEMO++ detector, a high-pressure xenon gas time projection chamber serving as a prototype for the NEXT-100 experiment, was used to measure the electroluminescence (EL) yie…
High Voltage Delivery and Distribution for the NEXT-100 Time Projection Chamber
NEXT Collaboration, C. Adams, H. Almazán +105
A critical element in the realization of large liquid and gas time projection chambers (TPCs) is the delivery and distribution of high voltages into and around the detector. Such e…
Reconstructing neutrinoless double beta decay event kinematics in a xenon gas detector with vertex tagging
NEXT Collaboration, M. MartÃnez-Vara, K. Mistry +108
If neutrinoless double beta decay is discovered, the next natural step would be understanding the lepton number violating physics responsible for it. Several alternatives exist bey…
Ion Transport on Phased Radiofrequency Carpets in Xenon Gas
E. Dey, B. J. P. Jones, Y. Mei +7
We present the design and performance of a four-phased radiofrequency (RF) carpet system for ion transport in high-pressure xenon gas. The RF carpet, designed with a 160 m pitc…
