Observation of Plasma Focusing of a 28.5 GeV Positron Beam
J. S. T. Ng, P. Chen, H. Baldis +17
The observation of plasma focusing of a 28.5 GeV positron beam is reported. The plasma was formed by ionizing a nitrogen jet only 3 mm thick. Simultaneous focusing in both transver…
The Cryogenic System of DMRadio-50L
V. Ankel, C. Bartram, J. Begin +36
The DMRadio-50L experiment is designed to search for axion dark matter in the 5 kHz - 5 MHz frequency range using a lumped-element LC resonator and a toroidal magnet and to serve a…
Observation of Two-Neutrino Double-Beta Decay in Xe-136 with EXO-200
N. Ackerman, B. Aharmim, M. Auger +100
We report the observation of two-neutrino double-beta decay in Xe-136 with T_1/2 = 2.11 +- 0.04 (stat.) +- 0.21 (sys.) x 10^21 yr. This second order process, predicted by the Stand…
Results on Plasma Focusing of High Energy Density Electron and Positron Beams
J. S. T. Ng, P. Chen, W. Craddock +19
We present results from the SLAC E-150 experiment on plasma focusing of high energy density electron and, for the first time, positron beams. We also discuss measurements on plasma…
Projected Sensitivity of DMRadio-m: A Search for the QCD Axion Below eV
DMRadio Collaboration, L. Brouwer, S. Chaudhuri +31
The QCD axion is one of the most compelling candidates to explain the dark matter abundance of the universe. With its extremely small mass (), axion dark ma…
Xenon purity analysis for EXO-200 via mass spectrometry
A. Dobi, C. Hall, S. Slutsky +73
We describe purity measurements of the natural and enriched xenon stockpiles used by the EXO-200 double beta decay experiment based on a mass spectrometry technique. The sensitivit…
