The Long-Baseline Neutrino Experiment: Exploring Fundamental Symmetries of the Universe
LBNE Collaboration, Corey Adams, David Adams +482
The preponderance of matter over antimatter in the early Universe, the dynamics of the supernova bursts that produced the heavy elements necessary for life and whether protons even…
Photon counting from the vacuum ultraviolet to the short wavelength infrared using semiconductor and superconducting technologies
Jonathan Asaadi, Dan Baxter, Karl K. Berggren +27
In the last decade, several photon counting technologies have been developed opening a new window for experiments in the low photon number regime. Several ongoing and future projec…
Enhancing Neutrino Event Reconstruction with Pixel-Based 3D Readout for Liquid Argon Time Projection Chambers
Corey Adams, Marco Del Tutto, Jonathan Asaadi +6
In this paper we explore the potential improvements in neutrino event reconstruction that a 3D pixelated readout could offer over a 2D projective wire readout for liquid argon time…
Temperature Dependent Optical Response Of High- Tc Yba2cu3o7-δ (Ybco) Thin Films
Vivek Khichar, V. A. Chirayath, Jonathan Asaadi +5
We report on the temperature-dependent optical response of thin films of YBa2Cu3O7-δ (YBCO) in the visible spectral range under cryogenic conditions. Specifically, we observe an i…
Component-Level Inverse Design of Transmon Qubits Using Neural Networks
Olivia Seidel, Firas Abouzahr, Abhishek Chakraborty +11
Designing a superconducting qubit to realize specific Hamiltonian parameters typically requires iterating through a time and compute-intensive forward loop in which the designer ch…
Research and Development for Near Detector Systems Towards Long Term Evolution of Ultra-precise Long-baseline Neutrino Experiments
Aysel Kayis Topaksu, Edward Blucher, Bernard Andrieu +108
With the discovery of non-zero value of mixing angle, the next generation of long-baseline neutrino (LBN) experiments offers the possibility of obtaining statistically si…
First operation of a multi-channel Q-Pix prototype: measuring transverse electron diffusion in a gas time projection chamber
Nora Hoch, Olivia Seidel, Varghese A. Chirayath +19
We report measurements of the transverse diffusion of electrons in P-10 gas (90% Ar, 10% CH4) in a laboratory-scale time projection chamber (TPC) utilizing a novel pixelated signal…
Snowmass Neutrino Frontier Report
Patrick Huber, Kate Scholberg, Elizabeth Worcester +56
This report summarizes the current status of neutrino physics and the broad and exciting future prospects identified for the Neutrino Frontier as part of the 2021 Snowmass Process.
Liquid argon purification and purity monitoring: apparatus and first results
Wenzhao Wei, I-see Warisa Jaidee, Spencer Dockal +14
We report results from a 13-liter purified liquid argon test stand at Wellesley College. The system includes a single-pass liquid-phase purification column, a double-gridded purity…
Demonstrating the Q-Pix front-end using discrete OpAmp and CMOS transistors
Peng Miao, Jonathan Asaadi, James B. R. Battat +7
Using Commercial Off-The-Shelf (COTS) Operational Amplifiers (OpAmps) and Complementary Metal-Oxide Semiconductor (CMOS) transistors, we present a demonstration of the Q-Pix front-…
Reconstruction of multiple Compton scattering events in MeV gamma-ray Compton telescopes towards GRAMS: the physics-based probabilistic model
Hiroki Yoneda, Hirokazu Odaka, Yuto Ichinohe +19
Aimed at progress in mega-electron volt (MeV) gamma-ray astronomy, which has not yet been well-explored, Compton telescope missions with a variety of detector concepts have been pr…
