Longitudinal double-spin asymmetries of charged hadrons with high transverse momentum p T have been measured in electroproduction using the Hermes detector at Hera. Processes involving gluons nucleon enhanced relative to others by selecting typically above 1 GeV. In this kinematic domain gluon polarization has extracted leading order making use model embedded Monte Carlo Generator Pythia 6.2. The obtained from single inclusive range GeV < 2.5 a deuterium target is $ \frac{{\Delta...
The difference in proton radii measured with $\mu p$ atoms and $ep$ scattering remains an unexplained puzzle. PSI MUSE proposal is to measure $e the same experiment at time. will determine cross sections, two-photon effects, form factors, independently for two reactions, allow results be compared reduced systematic uncertainties. These data should provide best test of lepton universality a date, about order magnitude improvement over previous tests. Measuring both particle polarities...
At Institut Laue-Langevin (ILL) and Paul Scherrer Institute (PSI), we have measured the losses depolarization probabilities of ultracold neutrons on various materials: (i) nickel-molybdenum alloys with weight percentages 82/18, 85/15, 88/12, 91/9, 94/6 natural nickel Ni100, (ii) nickel-vanadium NiV93/7, (iii) copper, (iv) deuterated polystyrene (dPS). For different samples, storage-time constants up to $\ensuremath{\sim}460\phantom{\rule{0.16em}{0ex}}\mathrm{s}$ were obtained at room...
Detectors of scientific instruments on spacecraft flying through Jupiter radiation belts need to be protected from high fluxes penetrating by means shields. Electrons constitute the most difficult component Jupiter's magnetosphere shield from, because their abundance, penetration depth in matter, and intensity bremsstrahlung generated upon interaction with shielding material. For Neutral Ion Mass spectrometer (NIM) Particle Environment Package (PEP) instrument suite board European Space...

Paul Scherrer Institut hosts the Proton Irradiation Facility used for radiation effects studies and exposure tests in preparation of satellite missions European Space Agency. The facility allows realistic simulation space proton spectra energy range from 6 MeV up to 230 with fluxes ranging very low as high 109 p/cm2/sec. Recently, approved ESA mission Jupiter—JUICE—also brought a need electron beams. For this purpose, another was established PSI secondary beam area piM1. Secondary particles...
LHCSpin aims at installing a polarized gas target in front of the LHCb spectrometer, bringing, for first time, physics to LHC. The project will benefit from experience achieved with installation an unpolarized during LHC Long Shutdown 2. then become experiment simultaneously running collider and fixed-target mode targets, opening whole new range explorations its exceptional spectrometer. offer unique opportunity probe quark gluon parton distributions nucleons nuclei, especially high $x$...
The MUon Scattering Experiment, MUSE, at the Paul Scherrer Institute, Switzerland, investigates proton charge radius puzzle, lepton universality, and two-photon exchange, via simultaneous measurements of elastic muon-proton electron-proton scattering. experiment uses PiM1 secondary beam channel, which was designed for high precision pion scattering measurements. We review properties line established pions. discuss production processes that generate electron muon beams, simulations these...
Abstract IMPACT (Isotope and Muon Production with Advanced Cyclotron Target Technologies) is a proposed initiative envisaged for the high-intensity proton accelerator facility (HIPA) at Paul Scherrer Institute (PSI). As part of IMPACT, radioisotope target station, TATTOOS (Targeted Alpha Tumour Therapy Other Oncological Solutions) will allow production terbium radionuclides therapeutic diagnostic purposes. The beamline be located near UCN (Ultra Cold Neutron source) area, branching off from...
Significant past work has identified unexpected risks of central nervous system (CNS) exposure to the space radiation environment, where long-lasting functional decrements have been associated with multiple ion species delivered at low doses and dose rates. As shielding is only established intervention capable limiting dangerous fields in space, recent discovery that pions, emanating from regions enhanced shielding, can contribute significantly total absorbed on a deep mission poses...
Ultracold neutrons were stored in a volume, using magnetic dipole field shutter. Radial confinement was provided by material walls. Low-field seeking axially confined above the field. High-field are trapped inside They can systematically shift measured neutron lifetime to lower values experiments with confinement.
