TITLE -ANALYZING POWER OF THE D(N,NP)N BREAKUP REACTION AT 2226500100015
67 MEV IN SELECTED KINEMATICAL CONFIGURATIONS. 2226500100016
FACILITY (CYCLO,2SWTPSI) 72 MEV INJECTOR CYCLOTRON AT PSI, 2226500100017
VILLIGEN. 2226500100018
INC-SOURCE (P-D ) POLARIZED NEUTRONS WERE PRODUCED WITH THE 2226500100019
(POLNS) D(P,N)PP REACTION BY BOMBARDING A LIQUID 2226500100020
DEUTERIUM TARGET WITH A 1 MICROAMP PULSED BEAM OF 2226500100021
POLARIZED PROTONS. THE NEUTRONS WERE EXTRACTED AT ZERO2226500100022
DEGREES THROUGH A COLLIMATOR HAVING AN OPENING ANGLE 2226500100023
OF 0.3 DEGREES. THE NEUTRON INTENSITY WAS ABOUT 2226500100024
5.0E+05 NEUTRONS/SEC. THE NEUTRON POLARIZATION WAS 2226500100025
ABOUT 0.36, AND WAS REVERSED EVERY 4 SECONDS. 2226500100026
INC-SPECT .AT ZERO DEGREES THE NEUTRON BEAM WAS QUASI-MONOENER- 2226500100027
GETIC WITH A FWHM OF ABOUT 3 MEV CENTERED AT 67 MEV. 2226500100028
SAMPLE .THE TARGET SCATTERER WAS PLACED AT 4.8 M DISTANCE FROM2226500100029
THE NEUTRON SOURCE. IT CONSISTED OF THE LIQUID SCIN- 2226500100030
TILLATOR NE213, CONTAINED IN A GLASS CYLINDER OF 4.9 2226500100031
CM DIAMETER AND 6.0 CM HEIGHT WITH ITS AXIS ORIENTED 2226500100032
VERTICALLY. MEASUREMENTS WERE PERFORMED WITH A FULLY 2226500100033
DEUTERATED SCATTERER. FOR CALIBRATION AND BACKGROUND 2226500100034
STUDIES, ORDINARY NE213 AND PARTIALLY DEUTERATED NE2132226500100035
SCATTERERS WERE ALSO USED. 2226500100036
METHOD (TOF ) THE NEUTRON BEAM SPECTRUM WAS DETERMINED BY 2226500100037
TIME-OF-FLIGHT BETWEEN THE TARGET SCATTERER AND THE 2226500100038
CYCLOTRON RF. THE LOW-ENERGY TAIL WAS CUT BY APPLYING 2226500100039
A SOFTWARE GATE OF 3.6 MEV SURROUNDING THE PEAK AT 2226500100040
67 MEV. THE ENERGY OF THE NEUTRONS WAS DETERMINED BY 2226500100041
THE TIME-OF-FLIGHT BETWEEN THE TARGET SCATTERER AND 2226500100042
THE NEUTRON DETECTORS. 2226500100043
(PSD ) PULSE-SHAPE DISCRIMINATION WAS USED FOR PAR- 2226500100044
TICLE IDENTIFICATION IN THE TARGET SCATTERER AND TO 2226500100045
REJECT GAMMA-RAY EVENTS IN THE NEUTRON DETECTORS. 2226500100046
(COINC) A CONICIDENCE BETWEEN THE TARGET SCATTERER AND 2226500100047
ONE OF THE NEUTRON DETECTORS WAS REQUIRED FOR A VALID 2226500100048
EVENT. 2226500100049
.BY MEASURING THE ENERGY OF THE PROTON AND THE ENERGY 2226500100050
AND DIRECTION OF ONE OF THE NEUTRONS, THE MEASUREMENT 2226500100051
IS KINEMATICALLY COMPLETE IN THE LIMIT OF N-P QUASI- 2226500100052

DETECTOR (SCIN ) THE ACTIVE TARGET WAS AN NE213 SCINTILLATION 2226500100054
DETECTOR. IT SUPPLIED INFORMATION ON THE ENERGY OF 2226500100055
THE CHARGED REACTION PRODUCT, PARTICLE IDENTIFICATION 2226500100056

BEAM ENERGY SPECTRUM VIA TIME-OF-FLIGHT VERSUS THE 2226500100058
CYCLOTRON RF-SIGNAL. 2226500100059
(SCIN ) THE NEUTRONS WERE DETECTED WITH EIGHT CYLINDRI-2226500100060
CAL NE213 SCINTILLATION DETECTORS, POSITIONED IN FOUR 2226500100061
SYMMETRICAL PAIRS ON BOTH SIDES OF THE BEAM. DETECTORS2226500100062
OF 14 CM DIAMETER AND 6 CM THICKNESS WERE USED AT 2226500100063
SMALL ANGLES, AND OF 10 CM DIAMETER AND 7.5 CM THICK- 2226500100064
NESS AT LARGE ANGLES. THE FLIGHT PATH VARIED FROM 3.0 2226500100065
M AT 20 DEGREES TO 1.0 M AT 150 DEGREES. THE ANGULAR 2226500100066
RESOLUTION RANGED BETWEEN 1.3 AND 2.8 DEGREES. NEUTRON2226500100067
ENERGIES WERE DETERMINED BY TIME-OF-FLIGHT, AND THE 2226500100068
ENERGY RESOLUTION WAS AROUND 1.5 MEV. PULSE-SHAPE 2226500100069
DISCRIMINATION WAS USED TO REJECT GAMMA-RAY EVENTS IN 2226500100070
THE DETECTORS. 2226500100071
.THE GAINS OF ALL SCINTILLATION DETECTORS WERE STABI- 2226500100072
LIZED USING LIGHT-EMITTING DIODES. 2226500100073
.THE PROTON BEAM INTENSITY AND POLARIZATION WAS MONI- 2226500100074
