The Design and Construction of RF System for Neutron Generator SAMES J-25 Ion Source

The design and construction of RF system for Neutron Generator SAMES J-25 ion source, which is nominated as neutron source on SAMOP system, have been done. As a neutron source of SAMOP system, neutron yield of the Neutron Generator has to be increased. One of the methods is by increasing its deuteron beam current. For RF type ion source, the beam current is influenced by oscillator power and its frequency, focusing system and extractor voltage. The design of RF system consists of determination of the desired output power and frequency by means of choosing active component that to be used and resolving oscillator LC tank. The choice of active component was adapted by the desire of output power while oscillator frequency was calculated based on configuration of inductor and capacitor being used. From the design and construction results of RF system, output power is obtained as 100 watt at oscillator frequency of 80 MHz. This result has earned to ionize neon gas, however it requires to be completed. (author)
