Original Abstract

There are several possibilities of the neutron flux determination inside of the facility. The most using one method is the determination of the neutron flux by threshold foils (detectors). This method is complicated to analyze. Irradiated foils need to be measured by gamma spectrometry and it usually takes a few weeks to get results of the neutron flux determination. Other methods are also available. One of them is the determination of the neutron flux by measuring of released heat inside of the facility. This method allows online measuring and is greatly variable to measure an unlimited number of positions in the facility with a low accrual of the cost. The research project to the topic of this type of neutron flux determination is led by Dzhelepov Laboratory of Nuclear Problems (DLNP) at the group of J. Adam. The temperature differences are measured by high accuracy thermocouples. Two experiments took place during 2015 at the massive spallation uranium target QUINTA at the facility Phasotron at JINR. Another four experiments are planned during 2016.
