F098900100004 AUTHOR (L.S.Azhgirey,Yu.P.Kumekin,M.G.Mescheryakov, F098900100005 S.B.Nurushev,G.D.Stoletov,H.De-Tsang) F098900100006 INSTITUTE (4ZZZDUB) F098900100007 REFERENCE (J,NP,43,213,1963) F098900100008 (J,ZET,44,177,1963) F098900100009 (J,JET,17,123,1963) English translation F098900100010 FACILITY (SYNCY,4ZZZDUB) The six-meter synchrocyclotron. F098900100011 INC-SOURCE On its way to the collimators an unpolarized proton F098900100012 beam is deflected in an auxiliary magnetic field by an F098900100013 angle of 14.2 degr. Thus the beam was purified of F098900100014 neutral and low energy particle admixture. F098900100015 Geometrically, the collimation was such that at the F098900100016 place of the scatterer the following conditions were F098900100017 fulfilled: a) the beam image on the autograph was 20 mmF098900100018 high and 10 mm wide and b) the horizontal plane beam F098900100019 divergence was equal to +-0.15 degr. Due care was takenF098900100020 to reduce the proton scattering effect in the F098900100021 collimator walls. F098900100022 DETECTOR (TELES,SCIN,CEREN) The scattered protons were F098900100023 registered by a telescope of 3 scintillation counters F098900100024 and one Cerenkov counter with a plexiglass radiator. F098900100025 MONITOR The averaged results of the measurements of the F098900100026 counting rate were used to plot the angular F098900100027 distribution of charged secondaries. The corresponding F098900100028 curve was then normalized to values of the F098900100029 differential cross sections for the emission of F098900100030 charged secondaries in p+C collisions, which were F098900100031 obtained earlier in L.Azhgirey,J,JETP,36,1631,1959, F098900100032 under conditions identical with those of the present F098900100033 experiments. The total energy spectrum of charged F098900100034 secondaries, measured at 7 degr., was also normalized F098900100035 to a value of the differential cross section for F098900100036 the same angles and equal to 1.1+-0.055 b/sr.
