G407500100014 DETECTOR (MAGSP,TELES,SCIN) A magnetic spectrometer with a G407500100015 subtended angle +-2 degree and a spark-chamber G407500100016 telescope. The proton polarization was detected and G407500100017 analyzed by a spark-chamber telescope and G407500100018 scintillation counters. The telescope contained two G407500100019 spark chambers, one with 10 gaps and foil electrodes G407500100020 to separate the proton direction, and one with 42 G407500100021 gaps and graphite electrodes measuring 250x250x6.7 mm, G407500100022 used for the proton-polarization analysis. Alignment G407500100023 of the spectrometer focal line with the second gap of G407500100024 the 42-gap spark chamber has made energy calibration G407500100025 of the focal line possible. G407500100026 METHOD (DSCAT) graphite electrodes as proton analyzer G407500100027 ERR-ANALYS (DATA-ERR) No information on sources of uncertainties.
