Dynamics of Magnetic Evaporative Beamline Cooling for Preparation of Cold Atomic Beams
A. Ashtari Esfahani, S. Bhagvati, S. Böser +55
The most sensitive direct neutrino mass searches today are based on measurement of the endpoint of the beta spectrum of tritium to infer limits on the mass of the unobserved neutri…
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…
Vertically stacked amorphous selenium based VUV photodetectors for use in liquid noble detectors
Iakovos Tzoka, M. Rooks, A. C. A. Ishida +3
We present results from the characterization of a vertically stacked amorphous selenium (aSe)-based photodetector for use in cryogenic environments. aSe has been identified as an i…
Monte Carlo analysis of the contributions of long-lived positronium to the spectra of positron-impact-induced secondary electrons measured using an annihilation-gamma-triggered time-of-flight spectrometer
S. Lotfimarangloo, V. A. Chirayath, S. Mukherjee +5
Magnetic bottle Time-of-Flight (ToF) spectrometers can measure the energy spectra of all electrons emitted into a 2 sr solid angle simultaneously, greatly reducing data collecti…
Efficient Machine Learning Approach for Optimizing the Timing Resolution of a High Purity Germanium Detector
R. W. Gladen, V. A. Chirayath, A. J. Fairchild +3
We describe here an efficient machine-learning based approach for the optimization of parameters used for extracting the arrival time of waveforms, in particular those generated by…
A multi-stop time-of-flight spectrometer for the measurement of positron annihilation-induced electrons in coincidence with the Doppler-shifted annihilation gamma photon
V. A. Chirayath, R. W. Gladen, A. D. McDonald +12
Here we describe an advanced multi functional, variable-energy positron beam system capable of measuring the energies of multiple positron-induced electrons in coincidence with the…
Coincident Measurement of the Energy Spectra of Doppler-Shifted Annihilation Gamma Quanta and Positron-Induced Secondary Electrons
R W Gladen, V A Chirayath, A J Fairchild +3
Preliminary results are presented from a new positron beam system currently under development at the University of Texas at Arlington for the coincident energy measurement of Doppl…
