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...
This article is a review of several accelerator–reactor interface issues and nuclear fuel cycle applications accelerator-driven subcritical systems. The systems considered here have the primary goal energy production, but that accomplished via specific application in various proposed cycles, such as breed-and-burn fertile material or burning transuranic material. Several basic principles are reviewed, starting from proton beam window including target, blanket, reactor core, up to cycle. We...

This project exploits charged particles confined as a storage ring beam (proton, deuteron, possibly $^3$He) to search for an intrinsic electric dipole moment (EDM, $\vec d$) aligned along the particle spin axis. Statistical sensitivities can approach $10^{-29}$~e$\cdot$cm. The challenge will be reduce systematic errors similar levels. adjusted preserve polarization, initially parallel velocity, times in excess of 15 minutes.

Several proposals to measure a possible small electric dipole moment (EDM) of charged particles aligned with the spin and well-known magnetic (MDM) are based on concept circulate bunches an initial polarization in horizontal plane observe buildup vertical component caused by EDM. Most aim at operating ring ``frozen spin,'' such that, MDM only, remains trajectory. The signature finite EDM is component. Machine imperfections may lead as well buildup, which can be misinterpreted thus limit...
