Neutron monitoring is quite important because neutron yield generated by fusion reactions corresponds to the fusion output. In design of the neutron monitor, Monte Carlo simulations play an important role to make corrections on various parameters, such as neutron energy spectrum and spatial distribution when determining the calibration constant. We consider the calibration procedures using a Cf point source toroidally rotating in the vacuum vessel, and evaluate uncertainties of the calibration constant for the neutron detector placed on the center axis.
