Magnet Applied Physicist / Engineer

What you'll do

You will join a team working on the design and integration of superconducting and resistive magnets for the muon collider project. The team is exploring candidate configurations that are above the current state of the art. including High-Temperature Superconductor (HTS) non-insulated magnets with fields up to 40T, with the goal of achieving high energy efficiency, operating in the 10K to 20K temperature range. You will contribute to the electromagnetic design and demonstration of magnets for production, cooling, acceleration, and collision of muons, particularly to the solenoids for the 6D and final cooling cells.

Your responsibilities

Contribute to the design of superconducting and resistive magnets for the cooling and acceleration chain of the muon collider.
Review present baseline and update the selection of magnet technologies based on performance, cost, and Technology Readiness Level (TRL).
Collaborate with technical teams to derive and refine magnet specifications.
Conduct analytical and numerical simulations (e.g., COMSOL, ANSYS, and other tools) to define performance limits and optimize magnet performance, with a focus on the solenoids of the 6D cooling channel.
Maintain a catalogue of superconducting magnet parameters, options, and configurations, contributing to the integration of magnet engineering with the broader machine configuration, in particular assessing mechanical and cryogenic constraints within the collider environment.
Assist in the organization of magnet development activities across multiple task groups.
