BF3 COUNTER TUBES

Proportional Counter Tubes BF3 Filled

The neutron sensitivity of these proportional counters

is achieved by  lling the tube with the gas boron-tri-

 uorid, made of highly enriched Boron-10. Thermal

neutrons react with the isotope Boron-10 emitting

alpha particles, which produce ionization in the gas

 lling of the detector (electrons and gas ions). In the

electrical  eld between the electrodes these charged

particles will be accelerated and secondary ionization

happens. This so called “gas ampli cation” multiplies

proportionally the amount of charge generated in the

tube.

APPLICATIONS

• Operational process monitoring

○ Detection and measurement of the thermal

neutrons outside the reactor core for neutron dose

rate monitoring and neutron  ux monitoring in the

pulse range
