After approximately 18 months, the SuperKEKB electron-positron collider was ready to restart its work. The long shutdown (LS1) provided ample time to upgrade the collider and the Belle II detector. Since 20 February Belle II is recording collision data again.
Björn Spruck from AG Sfienti is currently in Japan making sure the new Pixel Vertex Detector (PXD2), which was installed last year during LS1, is operational for successful data collection.
