Description
A BNCT online neutron monitoring system was tested in a TRIGA reactor, using a silicon PIN-diode with a conversion foil. The setup was tested with different reactor powers at the hot and cold ends of the irradiation channel, using activation foils to compare with measured fluxes. The results demonstrate good reproducibility and show a linear correlation between signal of the PIN-diode and neutron flux at all positions, demonstrating this approach to be suitable for online monitoring of the neutron flux. - Highlights: • A silicon PIN-diode with a conversion foil was tested for online neutron monitoring. • The system was evaluated for different reactor powers and irradiation sites. • The results show a linear correlation of the PIN-diode's signal with neutron flux.
