Belle II is a high-luminosity B quark factory facility located at the SuperKEKB electron-positron collider at the KEK laboratory in Japan. The main goal of Belle II is the search for evidence of new physics beyond the standard model of particle physics, through measurements of CP violation, rare decays, and searches for forbidden decays. It will improve the sensitivity to new physics by 1 to...

The Beast-II experiment aims to measure machine-induced backgrounds during commissioning of the SuperKEKB accelerator. The physical processes behind such backgrounds are notoriously difficult to simulate, hence the importance of conducting experimental validation as early as possible during the commissioning process. These results are critical to be able to predict the physics performance and...

The Belle II experiment at the KEK laboratory is currently undergoing
commissioning, with first physics data anticipated in 2018.
Understanding the material distribution of detector components is of
critical importance for precision e+e- collider experiments like
Belle-II, as the density and distribution of this material impacts
tracking and vertex reconstruction, as well as other aspects...

1769. MONITORING THERMAL NEUTRON BACKGROUNDS AT SUPERKEKB WITH $^3$HE PROPORTIONAL COUNTERS

In early 2016, BEAST, a detector designed to monitor beam conditions for SuperKEKB, was deployed for 4 months during phase-1 of beam commissioning. The BEAST detector consisted of multiple sub-detectors including the $^3$He proportional counters. During the beam commissioning the $^3$He tubes were successful in monitoring thermal neutron backgrounds caused by collisions with beam gas and...
