The base case with respect to which the magnetic field ranged has an ion current pulse amplitude of 0.7 mA at a rise time of 2.5 mks. The displacement of the solenoid towards the cathode entails an increase in the ion current pulse amplitude up to 1 mA but at the same time it leads to its spreading. The transfer of the solenoid toward the anticathode shortens the front of the ion current pulse, but leads to a decrease in its amplitude to 0.4 mA. At the low magnetic field intensity the current pulse front becomes steeper, but the pulse itself has a more sinusoidal shape with an amplitude of 0.6 mA. An increase in the magnetic field intensity entails an increase in the duration of the pulse front and an increase in its amplitude up to 0.5 mA while retaining a pulse shape close to rectangular.

The report examines the influence of the distribution and intensity of a magnetic field in the ion source with the Penning discharge of a gas-filled neutron tube on the ion current pulse. The study was carried out by means of numerical modeling using the KARAT code*. The ion source has a length of 1.1 cm, the length of the anode is 0.6 cm with its diameter of 1.1 cm. Atomic deuterium is used at a pressure of 1 mTorr as the residual gas. A ring-shaped hot cathode with an electron current of 10 mA is considered as the discharge trigger. The anode voltage pulse has an amplitude of 2.5 kV and a front of 0.5 mks. The magnetic field is created by a 1.1 cm long solenoid with a diameter of 2.3 cm. The base case with respect to which the magnetic field ranged has an ion current pulse amplitude of 0.7 mA at a rise time of 2.5 mks. The displacement of the solenoid towards the cathode entails an increase in the ion current pulse amplitude up to 1 mA but at the same time it leads to its spreading. The transfer of the solenoid toward the anticathode shortens the front of the ion current pulse, but leads to a decrease in its amplitude to 0.4 mA. At the low magnetic field intensity the current pulse front becomes steeper, but the pulse itself has a more sinusoidal shape with an amplitude of 0.6 mA. An increase in the magnetic field intensity entails an increase in the duration of the pulse front and an increase in its amplitude up to 0.5 mA while retaining a pulse shape close to rectangular.
