Openings

The EuPRAXIA Consortium is preparing a conceptual design for the world’s first multi-GeV plasma-based accelerator with industrial beam quality and dedicated user areas.
 
Do you want to become part of this endeavor?
 
Join us for your PhD Thesis on Electron beam instrumentation for Plasma Wakefield Accelerators
 
Instrumentation is is of particular importance for novel accelerating schemes. It allows benchmarking models of the accelerator with measurements, stabilizing the operation through feedbacks, diagnosing problems, and ensuring the safe operation of the accelerator. 
 
Do you have a strong motivation for experimental research on the forefront of accelerator physics, are you an open-minded person who enjoys working in an international team? 
 
In this thesis, you will design an instrument to measure and optimize the longitudinal phase space of the electron beam. To this aim, we are proposing to use an accelerating structure at several hundred GHz, such as to maximize the curvature in phase space. The longitudinal phase space is transformed to the transverse space and imaged on a profile monitor.
 
You will work on the design of instrumentation suitable for the planned EuPRAXIA accelerators. You will then perform first tests of this device in SwissFEL, a free electron laser based on a radio-frequency accelerator, located at the Paul Scherrer Institute in Villigen.
 
You will be part of the Laboratory of Particle Accelerator Physics at EPFL, and of the Electron Beam Instrumentation Group at PSI. We offer an attractive salary starting at 52’700 CHF gross per annum, and a stimulating multicultural working environment.
 
To apply, send a motivation letter, CV, and the contact information of at least two referees willing to write a reference letter to Esther Hofmann, recrui[email protected]

The EPFL Laboratory of Particle Accelerator Physics (LPAP) is looking for a motivated PhD student to contribute to the conceptual design study of a future muon collider.

High energy colliders are an essential tool for the study of elementary particles. As the standard model of particle physics is not complete, the study of particles with masses higher than those within the LHC’s reach is highly desirable. Colliding muons has several advantages over hadrons or electron and positrons when considering energies in the TeV range, notably in terms of energy efficiency. However as the muons are not available in matter, they need to be generated via the collision of a primary beam of protons, resulting in muon beams with a large beam size. As large beam sizes are not compatible with the high collision rate desired to study the physics of elementary particles, a process called ionisation cooling is needed in order to reduce the size of the muon beams. During this process, the high energy muons lose a fraction of their energy to blocks of matter via multiple ionisations. Existing models for this critical step of a muon collider only describe the trajectories of individual muons. The collective interactions of a beam composed of several muons  is unexplored. The student will study such collective interactions of the muons during ionisation cooling and understand the resulting performance limitations linked to the generation of beam instabilities.  

More details about the collaboration can be found at : Muon Collider Study 

The position becomes available asap. A Master’s degree (or equivalent) should be held by the start of employment.
The ideal candidate has a strong motivation for fundamental research, and has received education in Physics and/or engineering. Experience with data analysis, computer programming and/or particle accelerators is an advantage.
An attractive salary is offered [details are available at the following links 2, 3, 4], and the appointment runs for up to four years. EPFL, as well as CERN, offer a stimulating multicultural working environment at the forefront of
fundamental research. 

Applicants should prepare a single PDF file including the following documents: motivation letter, CV, and contact information of at least two referees willing to write a reference letter, and send it to Mrs. Hofmann at [email protected] by March 30th, 2023. Applicants should ask the referees to send their letters to the same address by the same deadline.
More information can be obtained from Dr. T. Pieloni ([email protected]).

The Application and the Letters of Reference should be sent to: [email protected]
