Event display of a cosmic muon track in the Mu3e vertex detector

Cosmic Run at PSI

We assembled a Mu3e vertex detector prototype and a ribbon of the fibre detector with their associated data acquisition (DAQ) at PSI. This setup was used to develop commissioning and tuning procedures for the sensors, advance DAQ integration, develop user interfaces, check timing and finally to detect cosmic ray muons passing through the set-up.

Mu3e Collaboration Meeting at PSI

After two years of virtual meetings, we held our first in-person collaboration meeting at PSI. We discussed the plans for detector construction and quality assurance, detector calibration and early physics analysis.

Dr Heiko

Heiko Augustin sucessfully defends his thesis on the development of the MuPix pixel sensors

Heiko Augustin co-developed and characterised many of the MuPix pixel sensor prototypes and introduced innovative solutions for the pixel control and the reduction of on-chip cross-talk. He now defended his thesis at Heidelberg University.

Mechanical Integration Mock-Up

Mechanical Integration Mock-Up

We have built a mock-up of the detector using a mix of final mechanics and PCBs, 3D-printed models as well as cables and tubes in order to establish the assembly procedure for the experiment and make sure everything fits into the extremely tight space.

Ioannis Paraskevas

Ioannis Paraskevas successfully defends his Ph.D. thesis on Mu3e commissioning

Ioannis Paraskevas commissioned the solenoid magnet and Mu3e beamline, developing simulations and carrying out measurements prior to the first Mu3e integration run. He also performed a study of fake tracks in simulation. He successfully defended his thesis during a virtual viva at University College London. Congratulations!

Mu3e Integration Run Setup

First Mu3e Integration Run

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.

Ramp up

Successful Ramp-up of the Mu3e Magnet at PSI

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.

Technical Design of the Phase I Mu3e Experiment published on the arXiv

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. 

The Mu3e Magnet arrived at PSI

We have received our solenoid magnet.
