CPNB
Boron - 10 Counter Tubes
The neutron sensitivity of these proportional
counters is achieved by coating of an electrode
with high enriched Boron-10. Thermal neutrons
react with the isotop Boron-10 emitting apha
particles, which produce ionization in the gas
filling of the detector (electrons and gas ions).
In the electrical field between the electrodes
these charged particles will be accelerated and
secondary ionization will happen. By the mean
of gas amplification the generated charge will
be multiplied proportional.
- Simple and rugged construction
- Detector may be supplied with or without cable
- Output sinal: charge pulses
- Very low Gamma sensitivity
- Temperature resistant up to 200°C

TK 250 NFM Digital Neutron Flux Channel
Digital signal processing solutions for safety related neutron flux applications.
Digital neutron flux measuring channels System
TK 250 are characterized
by efficient functions, useful procedures for
periodical testing, a comfortable operators
menue structure and a rugged operationial
behaviour. Hardware and software are arranged
in modules.
The internal multiprocessor structure offers the
flexibility of reducing the region of highest
safety relevance to a small, separated part
within the channel.
