This work presents results from an end-of run calibration campaign on EXO-200, using two candidate isotopes: 220-Rn and 222-Rn. We report observed alpha populations, efficiency corrections, and validation of EXO-200 fluid simulations using these data.

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.

We present here a series of projects underway that will provide advancements in background reduction, cryogenic readout, and physics searches beyond 0νββ, all moving toward the next-to-next generation CUPID-1T detector.

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.

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.

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.
