TITLE Fission fragment mass yields and total kinetic energy 1460000100003

INC-SOURCE (SPALL) 800 MeV protons beam onto an unmoderated 1460000100011
tungsten spallation target at WNR 1460000100012
DETECTOR (IOCH) Fission fragments were detected using 1460000100013
cylindrical ionization chamber with two back-to-back 1460000100014
detection volumes. 1460000100015
Both volumes used shared cathode between them and a 1460000100016
separate circular anode with Frisch grid. 1460000100017
Samples on carbon foil were secured to the cathode by 1460000100018
an Al ring. 1460000100019
Signal from the cathode was used for timing, two 1460000100020
signals from the anodes were used to determine energy 1460000100021
of charged particles. 1460000100022
Signals from the Frisch grid were used to determine 1460000100023
position of fission fragment. 1460000100024
METHOD (TOF) 90L WNR flight path with 11.9 m length. 1460000100025
The pulsed beam structure consisted of a series of 1460000100026
125 ps micropulses spaced 1.8 mu-s apart and grouped 1460000100027
into 675 us macropulses delivered at 40 Hz. 1460000100028
For production of low energy neutrons in 1L target, 1460000100029
the flight path was 22 m and macropulse repetition 1460000100030
rate was 20Hz. 1460000100031
ANALYSIS Energy of fission fragments was determined from 1460000100032
anode pulse heights. 1460000100033
CORRECTION Corrected for 1460000100034
- fragments energy loss in target, 1460000100035
- momentum transfer of the incident neutron, and 1460000100036
- gain differences between the preamps. 1460000100037
