Japan accelerator pursues nanobeams to boost luminosity Squeezing beams of electrons and positrons for the Belle II experiment at the SuperKEKB facility proceeds with halting progress.

@physicstoday.bsky.social has a new article about #belle2 and #SuperKEKB and our quest to reach higher luminosities:

Belle II 実験、再始動！ - 約1年半の長期メンテナンス後、はじめての電子・陽電子衝突を観測 - 名古屋大学 素粒子宇宙起源研究所（KMI） 2024年2月20日（火）に、Belle II 実験が物理測定用のデータ取得を再開しました。 Belle II

Belle2実験の Phase3 Run2 が開始しました！

長期メンテの間に、加速器と測定器を大幅にアップグレード。名古屋大学N研のメンバーも、TOPカウンターの光検出器を改良型へと交換しました🛠️

Belle II Restarts: First electron-positron collisions observed after 18 months maintenance - KMI - Nagoya University On February 20, 2024, the Belle II experiment resumed data acquisition for physics measurements. Belle II is a particle physics experiment designed to investigate the properties of particles, such as ...

Belle II Phase3 Run2 has started!

During the long-term maintenance, the photodetectors used in the TOP Counter were replaced with an upgraded model by members of N-Lab💡
