We are donating to the National Trust plant a tree scheme for every new joiner to Centronic. The aim of the scheme is to plant and establish 20 million trees by 2030, and we are proud to support it. It's also a nice thought that as a new joiner grows...Read more...
Centronic fission chambers can be used in either pulse or direct current (dc) mode. When used in pulse mode, non-neutron pulses can be discriminated against fairly easily, even at low neutron fluxes.
This makes pulse fission chambers ideal for use in high mixed fields. This makes them suitable for use as part of in-core or ex-core nuclear instrumentation. Small fission chambers, such as the Centronic FC4A, are designed for use in pulse mode for flux scanning in narrow tubes in the region of fuel elements.
Fission ion chambers are generally only used in dc mode for reactor control instrumentation. However, fission product activity limits the dynamic range of dc fission ion chambers to, typically, the top 2 decades of reactor power.
A wider range of neutron flux measurement can be obtained using fission chambers by use of the Campbelling measurement technique.
