摘 要:Purpose The Self Powered Neutrons Detectors(SPND)have the advantage of not requiring a high voltage power supply for their operation and are small in size,enhancing the interest of these detectors in *** In this context,we have developed a thermal neutron detection system based on *** detector was placed in the thermal channel of our nuclear research reactor;where the values of the current for each detector have been recorded as a function of time,with a chain in a current mode where electrometers without HV were *** We performed the real-time measurement of neutron flux during boron neutron capture therapy or boron neutron therapy,the different materials constituting the SPND detectors have been carefully chosen for this *** detectors were tested at a power of four MW corresponding to a neutron flux of 10^(9) n cm^(−2) s^(−1).Conclusions The usefulness of 103Rh-SPND is for online measurement of thermal neutron flux on BNCT patients has been demonstrated based on an appropriate calibration of the thermal neutron spectrum.
