Subject.- Temporary pulse systems for criticallity

Two identical systems using B F3 counters
One Boron lined conter system
The B10 line counter system may require more elaborate amplifier
system than the BF3 ounters. This will be determined by trial
after the counter is received. The rate meter and trip is ommitted
from one of the systems. One rate meter will be connected to a
recorder.
