Currently, PSI delivers the most intense continuous muon beam in world with up to a few 10 8 µ + /s. The High-Intensity Muon Beams (HIMB) project is developing new target station and beamlines able deliver /s, huge impact for low-energy, high-precision experiments. While next generation of proton drivers powers excess currently achieved 1.4 MW still require significant research development, focus HIMB improve surface yield geometry increase capture transmission solenoid-based beamline order...

The ITER tokamak includes 18 superconducting D-shaped toroidal field (TF) coils. Unavoidable shape deformations as well assembly errors will lead to errors, which can be modeled with the knowledge of current center line (CCL). Accurate survey during entire manufacturing and process, including transfer points, is complex.

The ITER tokamak includes 18 superconducting D-shaped toroidal field (TF) coils. Unavoidable shape deformations as well assembly errors will lead to error fields in the final configuration, which can be modeled with knowledge of current center line (CCL). We are building a room temperature magnetic measurement system using low-frequency ac excitation through TF coil and arrays pickup coils, fabricated printed circuit board technology.

Superconducting magnets cooled with cryocoolers become more and attractive due to an increasing cooling performance decreasing costs. This mode offers new perspectives high field like the possibility be installed where space is limited use in rotating systems. At Paul Scherrer Institute (PSI), two projects involving superconducting are ongoing: a compact 6 T super-bend for upgrade of Swiss Light Source has been designed concept generation proton therapy gantries cancer treatment was proposed...
The photon beam brightness of synchrotron light facilities is increased by reducing the emittance. For upgrade storage ring Swiss Light Source (SLS2), lattice achieving a low emittance foresees longitudinal gradient bending (LGB) magnets producing high peak field values and quasi-hyperbolic profiles to minimize at locations radiation. Two types technologies are studied: 1.4 T magnet based on permanent materials (PM-LGB) superconducting version (SC-LGB) working almost 5 peak, be upgraded 6 in...
In this work we present the design, construction and measurements of magnet for a so-called spin-rotator (Wien filter), beam line device used to rotate spin direction (and associated magnetic moment) muons in condensed matter research at Swiss Muon Source Paul Scherrer Institute. The design parameters-originating both from properties preferred particle as well technological constraints high-voltage components generating necessary electric field-were optimized compactness, cost high transmission.
