Gas-Filled Neutron Tube's Ion Source Modeling by the Karat Code
This article considers opportunity of the gas-filled neutron tube's ion source modeling by the KARAT code. To increase the efficiency of registration equipment in oil and gas logging, it is necessary to significantly reduce the duration of the neutron pulse front. To verify the adequacy of the numerical model, the experimental oscillograms of the extracted ion current and the discharge current was compared with the oscillograms obtained by simulating the work of gas-filled neutron tube GNT1-32 by the KARAT code under the same conditions. Despite the fact that the experimental oscillograms had a wide spread from pulse to pulse, the comparison showed a satisfactory agreement with the calculated data for such key parameters as the front time and pulse amplitude for both the extracted and the discharge current.
