Detection of scintillation light in noble gases with wavelength-shifting optical fibers
S. R. Soleti, S. Torelli, G. Martínez-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…
Demonstration of Sub-Percent Energy Resolution in the NEXT-100 Detector
NEXT Collaboration, M. Pérez Maneiro, M. Martínez-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…
The NEXT-100 Detector
NEXT Collaboration, C. Adams, H. Almazán +114
The NEXT collaboration is dedicated to the study of double beta decays of Xe using a high-pressure gas electroluminescent time projection chamber. This advanced technology…
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…
Performance of an Optical TPC Geant4 Simulation with Opticks GPU-Accelerated Photon Propagation
NEXT Collaboration, I. Parmaksiz, K. Mistry +113
We investigate the performance of Opticks, a NVIDIA OptiX API 7.5 GPU-accelerated photon propagation tool compared with a single-threaded Geant4 simulation. We compare the simulati…
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 pitch…
Fluorescence Imaging of Individual Ions and Molecules in Pressurized Noble Gases for Barium Tagging in Xe
NEXT Collaboration, N. Byrnes, E. Dey +112
The imaging of individual Ba ions in high pressure xenon gas is one possible way to attain background-free sensitivity to neutrinoless double beta decay and hence establish…
A Compact Dication Source for Ba Tagging and Heavy Metal Ion Sensor Development
K. E. Navarro, B. J. P. Jones, J. Baeza-Rubio +107
We present a tunable metal ion beam that delivers controllable ion currents in the picoamp range for testing of dry-phase ion sensors. Ion beams are formed by sequential atomic eva…
Neutral Bremsstrahlung emission in xenon unveiled
C. A. O. Henriques, P. Amedo, J. M. R. Teixeira +90
We present evidence of non-excimer-based secondary scintillation in gaseous xenon, obtained using both the NEXT-White TPC and a dedicated setup. Detailed comparison with first-prin…
Study of the loss of Xenon Scintillation in Xenon-Trimethylamine Mixtures
A. M. F. Trindade, J. Escada, A. F. V. Cortez +75
This work investigates the capability of TMA ((CH3)3N) molecules to shift the wavelength of Xe VUV emission (160-188 nm) to a longer, more manageable, wavelength (260-350 nm). Ligh…
Neutrinoless Double Beta Decay with SeF and Direct Ion Imaging
D. R. Nygren, B. J. P. Jones, N. Lopez-march +3
We present a new neutrinoless double beta decay concept: the high pressure selenium hexafluoride gas time projection chamber. Combining techniques pioneered in high pressure xenon…
