In nuclear medicine, the online blood radioactivity meter measures the radioactivity in the blood vessel to form the arterial input function in a dynamic PET study. Such a radioactivity meter is composed of scintillation crystals and SiPMs. The accuracy of the activity measurement varies with the temperature due to the temperature dependency in the gain of SiPMs and the light output of...
The Belle II experiment is designed to search for physics beyond the standard model of particle physics exploiting the large number of B meson decays produced by the SuperKEKB accelerator.
We have maintained a good data-taking efficiency since the beginning of our operation on March 2019.
Nevertheless, we encountered various problems and errors during our operation.
The instantaneous...
