We describe two new beamlines for radiation effects research at the Indiana University Cyclotron Facility. Protons with energies up to 205 MeV are available. One of the beamlines offers momentum selected beams at energies as low as 52 MeV. Beam characteristics such as transmission, energy, energy spread and lateral profile are described and compared to(More)
The SPIN Collaboration and the DESY Polarization Team have studied the possible acceleration of a polarized proton beam to 820 GeV/c in the HERA accelerator complex at DESY. The main problems which need further study are: increasing the accumulated polarized proton intensity, providing adequate spin stability with four or more Siberian snakes in HERA. All(More)
The analyzing power for proton-carbon elastic scattering in the Coulomb-nuclear interference region of momentum transfer, 9.0x10(-3)<-t<4.1x10(-2) (GeV/c)(2), was measured with a 21.7 GeV/c polarized proton beam at the Alternating Gradient Synchrotron of Brookhaven National Laboratory. The ratio of hadronic spin-flip to nonflip amplitude, r(5), was obtained(More)
A new pulsed neutron source is under construction at the Indiana University Cyclotron Facility (IUCF). Neutrons are produced via (p,n) reactions by a low-energy proton beam incident on a thin beryllium target. The source is tightly coupled to a cold methane moderator held at a temperature of 20 K or below. The resulting time-averaged cold neutron flux is(More)
The nuclear polarization of H(2) molecules formed by recombination of polarized H atoms on a Cu surface was measured as a function of external magnetic field and of temperature of the surface. The proton polarization of the molecules was determined by scattering of a longitudinally polarized 203-MeV proton beam in the Indiana University Cyclotron Facility(More)
We discuss the possible use of charge exchange reactions as a basis for a polarimeter at high energies. Measurements made at the AGS with polarized protons at a beam momentum of 22.1 GeVVc in a connguration suitable for polarimetry are presented. Large asymmetries are observed and the use of deuterium as a target looks particularly encouraging. Let me start(More)
We report the first observation of the charge symmetry breaking d+d-->4He+pi(0) reaction near threshold. Measurements using a magnetic channel (gated by two photons) of the 4He scattering angle and momentum (from time of flight) permitted reconstruction of the pi(0) "missing mass," the quantity used to separate 4He+pi(0) events from the continuum of double(More)
We describe a double-scattering experiment with a novel tagged neutron beam to measure differential cross sections for np backscattering to better than +/-2% absolute precision. The measurement focuses on angles and energies where the cross section magnitude and angle dependence constrain the charged pion-nucleon coupling constant, but existing data show(More)
which injects high energy protons into the Cooler via a transfer beam line. The dosimetry and EMI tests were performed in air by breaking the transfer beam line at the point X just before entry into the Cooler. Abstract A synchrotron has been constructed at the Indiana University Cyclotron Facility (IUCF) to inject 100 to 200 MeV protons into an electron(More)
