【Belle II Experiment】QCS Superconducting Magnets for Final Focusing of e-, e+ Beams Connected to Central Beam Pipes inside Belle II, Remote Vacuum Connection (RVC) Works Successfully.

From 10th to 15th of January, 2018, at KEK Tsukuba campus, where the SuperKEKB accelerator and the Belle II detector are being prepared for the first collisions of electrons (e-) and positrons (e+), the QCS superconducting magnets for final focusing of the beams were moved to the core of Belle II detector from both forward and backward sides and connected to the central beam pipe by the Remote Vacuum Connection (RVC) system, proposed and developed by Deutsches Elektronen-Synchrotron (DESY), one of the important collaborators of the Belle II Experiment.
