The 1st “Belle II Physics Week” was held at KEK

The Belle II Physics Week (Belle II Theory Interface Platform, B2TiP, Workshop) was held October 22-26, 2018 on the Tsukuba campus of KEK in the 3-go-kan seminar hall. The Physics Week continued the series of meetings previously held as part of the Belle II Theory Interface Platform series, which led to the publication of the Belle II Physics Book. This workshop was held just after the Belle II General Meeting (B2GM) which is a tri-annual plenary meeting in which a large number of Belle II members from many countries participate.

【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.

Installation of the Belle II Central Drift Chamber completed

On Oct. 13th 2016, the Central Drift Chamber (CDC) for the Belle II detector was successfully installed.

The CDC is a crucial sub-detector, as it provides the momentum of electrically-charged particles by reconstructing their curved trajectories while moving in a magnetic field. The information provided by the CDC is also a key ingredient of the Belle II trigger system. Additionally, the CDC contributes to particle identification by measuring the energy loss of charged particles as they pass through the gas that fills the CDC.
