Title: Present status of spin frozen deuteron target at KEK

Abstract

Brief report on the present status of a spin frozen deuteron target at KEK is presented. Deuterons in fully deterated propanediol (D-8) with EHBA-Cr/sup v/ complex were polarized up to 40% in a high cooling power dilution refrigerator which was installed in a large aperture spectrometer. 4 references, 5 figures.

  • A frozen spin target for the CEBAF Large Acceptance Spectrometer (CLAS) is under construction for a series of experiments that scatter tagged, polarized photons from both longitudinally and transversely polarized protons. Compared to the polarized target previously used inside CLAS, the proposed frozen spin target will better utilize the spectrometer's nearly 4pi acceptance. The target material will be dynamically polarized at 5 T and 0.3 K and then cooled to about 0.05 K by a horizontal 3He/4He dilution refrigerator. The polarization will be preserved by internal supercvnducting coils providing 0.3-0.5 T.
  • We present the results of our investigation of a series of internal holding magnets for longitudinal and transverse polarizations. These magnets will be placed inside a polarizing refrigerator designed for frozen spin targets. The studied magnets will provide the holding field in the range 0.3z0.5 T. The total thickness of the superconducting coils is of the order 0.5 mm. The frozen spin target is under construction for use in photo-nuclear experiments in concert with the JLAB Hall-B CLAS detector.
  • Investigations on N* production generally have to face large t- and u-channel background and broad, overlapping resonances. In order to disentangle the large variety of contributions it is necessary to employ not only unpolarized cross section data but also polarization data. Comparisons of PWA solutions and model calculations show that the presence of particular resonances in the s- channel have large effects on polarization observables. At Jefferson Lab, a major program has been proposed to perform a large set of experiments using linearly and circularly polarized photon beams and longitudinally and transversely polarized targets together with the large acceptance spectrometermore » (CLAS) in Hall B.« less
  • The FROST experiment at Jefferson Lab used the CLAS detector in Hall B with the intention of performing a complete measurement of polarization observables associated with strangeness photoproduction, in combination with data from previous JLab experiments. This was achieved by utilizing the FROST polarized target in conjunction with polarized photon beams, allowing direct measurement of beam-target double polarization observables. By studying strangeness reactions, such as {gamma}p {yields} K{sup +}{Lambda}{sup 0}, it may be possible to find 'missing' baryon resonances, predicted by symmetric quark models but not observed in previous experiments, whose results are consistent with the di-quark model. It ismore » thought these 'missing' resonances remain undiscovered because they have different coupling strengths for different reaction channels, such as the strangeness reactions, whereas the current data is dominated by studies of pN reactions. Observing these resonances therefore has important implications for our knowledge of the excited states of nucleons, and the models predicting the quark interactions within them. The G polarization observable is one of the beam-target double polarization observables, associated with a longitudinally polarized target and a linearly polarized photon beam, and its measurement for the strangeness reaction {gamma}p {yields} K{sup +}{Lambda}{sup 0} is the focus of the work presented.« less
  • The helicity asymmetry for single neutral pion photoproduction was measured using the CLAS detector in Hall B at the Thomas Jefferson National Accelerator Facility. This measurement used longitudinally polarized protons and circularly polarized photons with photon energies between 0.35 GeV to 2.4 GeV. The target was a frozen-spin butanol (C{sub 4}H{sub 9}OH) target, polarized at about 85%. The helicity asymmetry E for the {gamma}p {yields} p{pi}{sup 0} was measured with missing-mass technique at the high statistics of about 12 x 10{sup 6} events. The experimental results are compared to three available theoretical predictions, SAID, MAID, and EBAC. The preliminary resultsmore » are in good agreement with the model calculations at low E{sub {gamma}} energy bins. However, a significant deviation is observed at high energy bins. Therefore, the new data will help to constrain the parameters of the theoretical models.« less
