To realize this special phoswich cell, two unique inventions
were successfully done.
First plastics scintillator which has very high resistivity to
liquid scintillator chemical attack with high relatie light
output and long decay timing was developed by ELJEN.
Secondary, very special liquid scintillator which has equivalent
prperties to EJ-301 (NE-213 equiv.) but has quite low chemical
attack characteristics to plastics was also developed.
Finally, precision machining work team at ELJEN realized this
unique plastics cell which ahs 187 small inner holes filled by
EJ-399-06 special liquid scintillator.
