PROZA-M experiment results as well the proposal of a new spin program with the use of a polarized proton beam are presented. Significant asymmetries were observed in inclusive π production. The new program proposes to study a wealth of singleand double-spin observables in various reactions using longitudinally and transversely polarized proton beams at U70. The main goal is to define gluon cont...

The STAR experiment at the Relativistic Heavy Ion Collider (RHIC) has a rich spin physics program aimed at exploring the spin structure of the proton with polarized proton beams. In addition to the currently accessible channels, heavy flavor, charged vector boson production and forward mesons are integral parts of the long-term program. Such measurements require upgrades of the STAR tracking sy...

Response of a micro volume (0.01 ml) ionization chamber has been studied with pulsed proton beams which are used for clinical purposes and has been compared with those of some JARP ionization chambers (0.6 ml). All chambers used had been calibrated by standard 60Co beams at the Electrotechnical Laboratory (ETL) and exposure calibration factors, Nx, were obtained on advance. Two methods are used...

The electric fields produced by the interaction of ultra-short and ultra-intense laser pulses with a thin target make it possible to obtain multiMeV , high density, highly collimated proton and ion beams with duration in the sub-picosecond range. Critical features are the efficiency of the ion acceleration process and the energy spectrum of the produced ion beam. At high laser intensities the r...

We comment on a recent article (Gomà et al 2014 Phys. Med. Biol. 59 4961-71) which compares different routes of reference dosimetry for the energy dependent beam monitor calibration in scanned proton beams. In this article, a 3% discrepancy is reported between a Faraday cup and a plane-parallel ionization chamber in the experimental determination of the number of protons per monitor unit. It is...

Different fields and disciplines in Science and Technology are imposing more stringent and accurate measurements of the proton and neutron total and differential cross-sections in the intermediate-energy range, from a few dozens of MeV up to a few GeV. Such measurements could be performed in facilities disposing of proton or light ion beams (namely facilities to produce Radioactive Nuclear Beam...

The need for intense muon beams for muon colliders [1] and for neutrino factories based on muon storage rings [2, 3, 4] leads to a concept of 1-4 MW proton beams incident a moving target that is inside a 20-T solenoid magnet, with a mercury jet as a preferred example. Novel technical issues for such a system include disruption of the mercury jet by the proton beam and distortion of the jet on e...

A scanned proton beam yields dose distributions that in most cases are superior to other external radiation treatment modalities, and also to passively scattered proton beams. The present paper gives a description of the scanning system that has been developed at the The Svedberg Laboratory (TSL) in Uppsala. The solution with a small polegap of the magnets and a moveable second magnet gives a v...

The present status of neutron-proton scattering in the energy range from 20-70 MeV is reviewed. The data base covers total cross sections, differential cross sections and polarization observables. The efforts after 1980 did largely cnncentrate on precision measurements of the differential cross sections and accurate vector analyzing powers, using polarized neutron beams. Because of correlations...

There will be a review of the history of polarized proton beams, and a discussion of the unexpected and still unexplained large transverse spin effects found in several high energy proton-proton spin experiments at the ZGS, AGS and Fermilab. Next, there will be a discussion of present and possible future experiments on the violent elastic collisions of polarized protons at IHEP-Protvino’s 70 Ge...
