Possible Experiments with Polarized Neutrons at the Zgs and at Fnal

چکیده

Experiments with polarized neutrons at high energy have interested me recently for at least five reasons as follows: (i) Our Michigan group has over the past decade evolved a program of hadronic physics with neutron beams at the Bevatron, the ZGS, the AGS, and at FNAL so that we feel quite familiar with the problems and 1 techniques in this area (2) The Argonne ZGS has discussed plans to accelerate polarized deuterons; the neutrons from the stripped deuteron beam will provide a collimated, intense, reasonably monochromatic polarized neutron beam of up to 6 GeV. (3) The observed polarization of inclusively-produced A°s by Overseth's group at FNAL and CERN begs the investigation of polarization in other inclusive phenomena such as neutron 2 production . (4) J. Rosen et al. have recalled 3 that the Schwinger Effect 4 can produce up to 100% polarization of neutrons in elastic scattering at very small angles at high energies and outlined possible experiments at Fermilab. (5) During the winter and spring of this year I was a guest of Westfield College (London) where Elliot Leader stimulated my interest in various polarization phenomena accessible though small angle 5 neutron scattering. Drawing these factors together has lead to the conception of a series of possible experiments at both Argonne and Fermilab which I will sketch herein. Fundamental to the class of experiments I am discussing is the interference between the electromagnetic

Violent Collisions of Spinning Protons

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...

بررسی امکان استفاده از چشمه های نوترونی رادیوایزوتوپی در نوترون درمانی با بور

  Background : Performing successful BNCT experiments needs a suitable neutron source. Important factors of the neutron beam are flux and energy that are very important in the selection of neutron source. In most centers that use this method for treatment, reactor is a neutron source, which according to characteristics of the reactor appropriated neutrons are very high. High cost of constructin...

Neutrino oscillation physics with a FNAL proton driver

The Fermilab proton driver (FPD) is proposed to consist of a linear accelerator and several main injector modifications. Its purpose is to provide higher fluxes to potential experiments, such as neutrino oscillation experiments [1,2], or muon, kaon, pion, neutron, or antiproton experiments [1]. It is aiming for 8GeV and (up to) 120GeV protons at about 2MW, which is a factor of five to ten past ...

Experiments with polarized 3 He at MAMI

Experiments with polarized 3 He at MAMI have already a long tradition. The A3 collaboration started in 1993 with the aim to measure the electric form factor of the neutron. At this time MAMI was the second accelerator where experiments with 3 He were possible. Some years before this pilot experiment the development of the apparatus to polarize 3 He in Mainz started. There are two techniques whi...

Structure functions in polarized proton-deuteron Drell-Yan processes

Polarized proton-deuteron (pd) Drell-Yan processes are investigated for studying new spin structure of a spin-1 hadron. Our formalism indicates that there exist many structure functions: 108 in general and 22 in the QT-integrated case. A naive parton model suggests that at least one of them should be related to the tensor polarized distributions, which have not been measured at all. There are s...
