abstract
We report a study on the background of the Advanced Molybdenum-Based Rare process Experiment (AMoRE), a search for neutrinoless double beta decay (\znbb) of $^{100}$Mo. The pilot stage of the experiment was conducted using $\sim$1.9 kg of \CAMOO~ crystals at the Yangyang Underground Laboratory, South Korea, from 2015 to 2018. We compared the measured $\beta/\gamma$ energy spectra in three experimental configurations with the results of Monte Carlo simulations and identified the background sources in each configuration. We replaced several detector components and enhanced the neutron shielding to lower the background level between configurations. A limit on the half-life of $0\nu\beta\beta$ decay of $^{100}$Mo was found at $T_{1/2}^{0\nu} \ge 3.0\times 10^{23}$ years at 90\% confidence level, based on the measured background and its modeling. Further reduction of the background rate in the AMoRE-I and AMoRE-II are discussed.

Cryogenic light detectors with thermal signal amplification for $0\nu\beta\beta$ search experiments
NTL-amplified germanium light detectors in a 10-crystal cryogenic array achieve a signal-to-noise gain near 9, sub-millisecond rise time, and projected pile-up background close to the CUPID goal.

Opportunities and challenges to study solar neutrinos with a Q-Pix pixel readout
Simulations show a Q-Pix liquid argon detector could, in a low-background underground scenario, see boron-8 and hep solar neutrinos above about 5 MeV if poorly understood gamma and alpha-capture backgrounds are controlled.
