The Institute for Particle Physics and Astrophysics (IPA http://www.ipa.phys.ethz.ch/) of ETH Zurich invites applications for one PhD position in experimental Particle Physics, to work on the Mu3e experiment at the Paul Scherrer Institute (PSI).

 

Mu3e is a novel experiment designed to search for the charged lepton flavor violating decay μ+ → e+ e- e+. This decay is only allowed at an extremely low and undetectable rate in the Standard Model; hence, its observation would unambiguously point to the existence of new physics. The experiment is expected to start physics operations around 2024. The IPA Mu3e group has a strong involvement in the construction of a novel scintillating fiber (SciFi) detector for very precise timing, including the completion of its mechanical concept, the development of very fast readout electronics and its integration in the data acquisition of the experiment.

The group is looking for outstanding applicants on the M.Sc level, ideally with some research experience in Experimental Particle Physics and a strong interest in detector development. Adequate programming skills (C++, python) are required, possibly including some knowledge on firmware development. Previous experience with hardware and electronics will be an advantage.

The subject of the thesis is the development, integration, commissioning, and operation of the SciFi detector. At a first stage, the candidate is expected to participate in the prototyping and testing of the front-end readout electronics in test beam experiments. This includes data reconstruction and analysis to characterize the detector performance, in particular under the effects of irradiation. Additionally, the student will join the group effort towards the integration of the SciFi readout in the FPGA-based data acquisition system of Mu3e. Ultimately, the candidate will play a leading role in the installation and exploitation of the SciFi detector during Mu3e physics operations, including data taking and the development of the first data analyses.

Candidates are required to actively participate in the teaching activities of the Physics Department (about 20-25% of level of effort). The initial term of the position is 18 months during which an aptitude colloquium will have to be passed pursuant the doctoral ordinance of ETH Zurich. The position is financed up to four years. Interested candidates are asked to submit their application by 25 April 2022 together with a letter of motivation, the names and contact details of two referees and a curriculum vitae. The application should be sent via email only to ipa-cms-phd@phys.ethz.ch.

Recommendation letters will be solicited from the provided contact information as appropriate. Inquiries concerning the position can be made to Prof. Rainer Wallny (rainer.wallny@phys.ethz.ch) (please mention “ETH Scifi Mu3e PhD:” in the subject line). The envisaged start of the contract is 1 June 2022 or later upon mutual agreement.
