Description
GRAAL experiment installed a high energy up to 1.5 GeV tagged and polarized photon beam at the ESRF (European Synchrotron Radiation Facility) in Grenoble. The beam is produced by backscattering a laser beam of the electron beam of the ESRF. This beam is used to study the photoproduction of mesons on liquid hydrogen target. From October 1996 until May 1997 data taking was performed to produce η mesons on hydrogen from threshold to 1100 MeV. The extraction of beam asymmetry Σ in η photoproduction is in preparation for publication. The analysis of π0 and 2π0 photoproduction is in progress and the cross sections of the three channels are under analysis. In September 1997, the tests of kaon photoproduction and detection is being started with photon beam of energy up to 1500 MeV. (authors)
