Then the beam was G407300100015 delivered into experimental area and was directed onto G407300100016 photon radiators. The beam size on the radiators was G407300100017 no more than 2 mm, and the electron current was about G407300100018 5...10 nA. The polarized photon beam has been G407300100019 produced at process of a coherent bremsstrahlung of G407300100020 electrons in a diamond crystal of 100 mu-m thick. G407300100021 METHOD (EDE) G407300100022 SAMPLE Two targets, a 1.1mm CH2 and a 1mm CD2 thickness G407300100023 plates, were used for measurements. The targets were G407300100024 positioned on the distance about 2 m from the photon G407300100025 collimator at angle 30 degrees to the photon beam G407300100026 direction. The numbers of carbon nuclei per cm2 were G407300100027 0.885e22 cm-2 for the CH2 target and 0.771e22 cm-2 G407300100028 for the CD2 target, the number of deuteron nuclei per G407300100029 cm2 was 1.541e22 cm-2. G407300100030 DETECTOR (TELES,CSICR,SISD) Protons were detected by a CsI/SSD G407300100031 telescope, placed under angle 90 degrees to the beam G407300100032 axis. It consisted of two identical single-sided G407300100033 silicon strip detectors and a CsI(Tl) counter, which G407300100034 functioned as deltaE and E detectors, respectively. G407300100035 The SSDs had a thickness of 0.5 mm and 64 strips, G407300100036 each of 1 mm width, which were paralleled in groups G407300100037 of two for the read-out, thus yielding an effective G407300100038 strip width of 2 mm. The CsI(Tl) detector was of G407300100039 cylinder shape of 12.5 cm in diameter and 10 cm long, G407300100040 housed in Al container. G407300100041 ERR-ANALYS (ERR-S) Statistical errors are presented. G407300100042 The systematic uncertainty was estimated to be about G407300100043 10%, and arises from error of the random background G407300100044 spectra normalization at the background subtraction G407300100045 (about 7%), and accuracy of the polarization G407300100046 determination (about 5%).
