The Dynamics of Ions on Phased Radio-frequency Carpets in High Pressure Gases and Application for Barium Tagging in Xenon Gas Time Projection Chambers
NEXT Collaboration, B. J. P. Jones, A. Raymond +107
Radio-frequency (RF) carpets with ultra-fine pitches are examined for ion transport in gases at atmospheric pressures and above. We develop new analytic and computational methods f…
Mitigation of Backgrounds from Cosmogenic Xe in Xenon Gas Experiments using He Neutron Capture
L. Rogers, B. J. P. Jones, A. Laing +89
\Xe{136} is used as the target medium for many experiments searching for \bbnonu. Despite underground operation, cosmic muons that reach the laboratory can produce spallation neutr…
Initial results on energy resolution of the NEXT-White detector
J. Renner, P. Ferrario, G. Martínez-Lema +77
One of the major goals of the NEXT-White (NEW) detector is to demonstrate the energy resolution that an electroluminescent high pressure xenon TPC can achieve for high energy track…
High Voltage Insulation and Gas Absorption of Polymers in High Pressure Argon and Xenon Gases
L. Rogers, R. A. Clark, B. J. P. Jones +3
High pressure gas time projection chambers (HPGTPCs) are made with a variety of materials, many of which have not been well characterized in high pressure noble gas environments. A…
In-situ calibration of a PMT inside a scintillation detector by means of primary scintillation detection
NEXT Collaboration, V. Álvarez, F. I. G. M. Borges +75
We have investigated the possibility of calibrating the PMTs of scintillation detectors, using the primary scintillation produced by X-rays to induce single photoelectron response…
