The photon beam G407200100011 had a maximum intensity and almost 90% degree of G407200100012 polarization at energies below 40 MeV. Polarization G407200100013 decreased from 88% in the range of the reaction G407200100014 threshold to 58% at Eg = 50 MeV. G407200100015 DETECTOR (TRD) A two-gap streamer chamber with a working G407200100016 volume of 60x60x24 cm3, was filled with pure helium G407200100017 to a pressure of 101325 Pa. The chamber was placed in G407200100018 an axially symmetric magnetic field with intensity G407200100019 about 1 T, known with an accuracy of 0.2%. The G407200100020 working volume of the camera was photographed with a G407200100021 three-lens camera. G407200100022 SAMPLE Pure helium to a pressure of 101325 Pa.
