L016100100020 DETECTOR (HPGE) Gamma rays from the target were measured with L016100100021 a HPGe detector array positioned about 4.8 m L016100100022 downstream from the collimator. The array consists L016100100023 of four HPGe detectors with 60% efficiency, positioned L016100100024 10 cm away from the center of the target and at an L016100100025 angle of 90 deg relative to the photon beam. Two L016100100026 detectors were located in the horizontal plane and two L016100100027 in the vertical plane. L016100100028 METHOD (GSPEC) L016100100029 MONITOR (5-B-11(G,SCT),PAR,ARE) L016100100030 INC-SOURCE (LCS) Monoenergetic photons, with high L016100100031 polarization and selectable energy, were produced at L016100100032 the HIgS facility using intracavity backscattering of L016100100033 free-electron-laser (FEL) photons from electrons in L016100100034 the DFELL storage ring. Photon energy was changed L016100100035 from 2 MeV to 4 MeV with resolution of 5 %. The L016100100036 linear polarization of the beam was almost 100%.
