During an extensive campaign at PSI, the Mu3e collaboration for the first time operated parts of the detector inside the experiment magnet and with muon beam stopping on a target in the center of the experiment.

The Mu3e magnet has been successfully ramped up to 1T by Andreas Knecht and Ioannis Paraskevas with the remote help from Roger Mitchell from Cryogenic. This included both the main and compensation coils. It went very smoothly and no re-centering of the cryostat was necessary. The load cells showed a very balanced configuration. Congratulations to everybody involved for reaching this important milestone.

In almost a decade of R&D, we have developed a detailed technical design for the Mu3e experiment, based on many new and exciting detector technologies. 

Resuming beam operations, we have the opportunity to test a part of the data acquisiston sytem using the electron beam at the Mainz Microtron. We operate four pixel planes via two different front-end board prototypes to test the synchronization of across the system.

We lost a very good friend and an important consultant for the design and construction of the magnet for our experiment.

During the Corona crisis, meetings are only possible online. The Mu3 collaboration met today virtually with more than 20 people from three different countries.

During a week of beam tests at DESY, Hamburg, we for the first time took data with the pixel, fibre and tile detectors running in a common data acquisition setup. The lessons learned are key to completion and comissioning of the complete detector readout.

Data Acquisition experts from all subsystems got together in the Mu3e DAQ lab in Mainz to integrate hardware, firmware and software into a common system. For the first time, we ran the full Mu3e timing and reset system and in general made good progress towards common data taking at high rates.
