Energy, time, and position resolution measurements of an array of large tapered LYSO crystals
O. Beesley, J. Carlton, D. Ding +19
We report on the performance of six custom-made tapered LYSO crystals of unprecedented volume, which constitute a sector of the 19 radiation length electromagnetic calorimeter plan…
Synthesis of a high intensity, superthermal muonium beam for gravity and laser spectroscopy experiments
Jesse Zhang, Aldo Antognini, Marek Bartkowiak +8
The universality of free fall, a cornerstone of Einstein's theory of gravity, has so far only been tested with neutral composite states of first-generation Standard Model (SM) part…
European Strategy for Particle Physics Update -- PIONEER: a next generation rare pion decay experiment
PIONEER Collaboration, A. Adelmann, W. Altmannshofer +76
PIONEER is a rapidly developing effort aimed to perform a pristine test of lepton flavour universality (LFU) and of the unitarity of the first row of the CKM matrix by significantl…
Measurements of a LYSO crystal array from threshold to 100 MeV
O. Beesley, J. Carlton, B. Davis-Purcell +16
We report measurements of ten custom-made high-homogeneity LYSO crystals. The investigation is motivated by the need for a compact, high-resolution, and fast electromagnetic calori…
