Characterization of single layer anti-reflective coatings for bolometer-based rare event searches

Published in Journal of Instrumentation, 2017

Combining analysis from phonon signals and photon signals is a powerful technique for reducing backgrounds in bolometer-based rare event searches. Anti-reflective coatings can significantly increase the performance of the secondary light-sensing bolometer in these experiments. As a first step toward these improvements, coatings of SiO(2), HfO(2), and TiO(2) on Ge and Si wafers were fabricated and characterized at room temperature and multiple angles of incidence.

Radon Injection for Light Response Calibration of the nEXO Detector

Published in ProQuest, 2019

I present results from an end-of run calibration campaign on nEXOs predecessor experiment, EXO-200, using two candidate isotopes: 220-Rn and 222-Rn. I report observed alpha populations, efficiency corrections, and validation of EXO-200 fluid simulations using these data. This work also presents a new framework that combines fluid simulations with nEXO Monte Carlo to produce position-dependent functions of the detector response to light. Finally, I propose possible calibration schemes for radon injection for the nEXO detector.

Transforming U.S. Particle Physics Education: A Snowmass 2021 Study

Published in arXiv preprint, 2022

We performed a survey of the U.S. particle physics community to determine the missing elements of graduate and undergraduate education and to gauge how to bridge these gaps. In this contributed paper, part of the 2021-22 Snowmass Community Planning Exercise, we report the results of this survey. We also recommend several specific community actions to improve the quality of particle physics education; the “community” here refers to physics departments, national labs, professional societies, funding agencies, and individual physicists.

Climate of the Field: Snowmass 2021

Published in arXiv preprint, 2022

We present a discussion of the current climate of the field in high energy particle physics and astrophysics (HEPA), as well as current efforts toward making the community a more diverse, inclusive, and equitable environment. We also present issues facing both institutions and HEPA collaborations, with a set of interviews with a selection of HEPA collaboration DEI leaders. We encourage the HEPA community and the institutions & agencies that support it to think critically about the prioritization of people in HEPA over the coming decade, and what resources and policies need to be in place in order to protect and elevate minoritized populations within the HEPA community.

Novel techniques for characterizing detector response for the nEXO experiment

Published:

Large, ultra-low background liquid xenon detectors are a promising technology that can push the neutrinoless double beta decay search to unprecedented sensitivity. Observation of this decay would demonstrate lepton number violation and the Majorana nature of the neutrino. The nEXO experiment will search for neutrinoless double beta decay of Xe-136 using 5 tons of enriched liquid xenon in a low-background single-phase time projection chamber and is expected to reach a 10-year sensitivity of ~1028 years. I will discuss the most recent results from the precursor experiment, EXO-200, as well as techniques for light and charge calibration currently under study by the nEXO collaboration, including results from testing and simulation of dissolved calibration sources capable of characterizing the center of nEXO’s large drift chamber.
