Huangshan Chen successfully defends his thesis on the development of the MuTRiG ASIC for the Mu3e timing detecors
Huangshan Chen was instrumental in the development of the MuTRiG ASIC, which performs the time-to-digital conversion for the Mu3e fibre and tile timing detectors. He has now successfully defended his thesis at Heidelberg University.
Ann-Kathrin Perrevoort successfully defends her PhD thesis on the sensitivity of the Mu3e experiment for new physics and pixel frontend firmware.
Ann-Kathrin Perrevoort studied the sensitivity of the Mu3e experiment for the main search channel using an effective field theory approach and also simulated the performance for searches for two-body decays of the muon and electron-positron resonances. In addition she contributed a core piece of the pixel front-end firmware, namely the real-time time sorting of hits.
Meeting on Mu3e detector integration in Wengen
We spent four days in Wengen, Switzerland going over the details of the Mu3e detector integration and discussing the procedures for producing the sub-detectors. Safety, powering, cooling, electronics and readout were also among the topics.
Zachary Hodge successfully defends his PhD thesis on the Mu3e beam line design and monitoring
Zachary Hodge made extensive simulations for the Mu3e muon beam line at PSI, including some upgrade of the muon target E at PSI, which is supposed to improve the muon beam rate significantly. He co-developed a monitoring scheme using a scintillating target and a CCD camera for beam characterization and monitoring.
Review of Mu3e at PSI
Mu3e has passed a detailed review at the PSI proton accelerator users meeting. Beam time in 2018 was granted for tests of the timing and pixel detectors as well as for further development of the compact muon beam line (CMBL).
Dorothea vom Bruch successfully defends her Ph.D. thesis on the Mu3e filter farm and MuPix timing behaviour
Dorothea vom Bruch developed and implemented the algorithms for the Mu3e filter farm, showing that just 12 PCs with powerful GPUs are sufficient to reduce over 10 Gbyte/s of data to manageable levels. She also performed detailed studies of the position dependent timing behaviour of the MuPix7 HV-MAPS prototype. She has now successfully defended her thesis in Heidelberg.
First MuPix8 beam test at DESY
We are testing our new large sensor chip, the MuPix8, in the electron beam at DESY, Hamburg. One of the high resolution EUDET telescopes serves as a reference for efficiency and resolution measurements.
Collaboration meeting in Mainz and new collaborators
In a two day meeting in Mainz we had the pleasure of welcoming four new institutes, namely the universities of Liverpool, Oxford and Bristol as well as University College London to the collaboration. We also discussed progress on all subdetectors and a variety of integration issues.
MuPix8, our first large sensor, has arrived
We have just received first samples of the MuPix8 chip from the foundry. This is our first large (20mm x 10mm) pixel sensor prototype and a big step on the way to building the Mu3e tracking detector. The prototype will now be thoroughly tested in the labs in Karlsruhe and Heidelberg and will also soon see first beam at DESY in Hamburg, PSI and MAMI in Mainz.
