The special feature of this generator type is the possibility to generate neutron pulses having duration from 5...10 microsec to several milliseconds and frequency from hundreds Hz to tens kHz. 14 MeV neutron yield - 10⁴...10⁶ n/pulse.

The ING-07 generator using gas-filled tube and its modification specially for elemental analysis equipment ING-17 (Table 1) are currently developed and being produced at VNIIA. The generator includes:

• control console (personal computer - for the ING-17 generator);

• power supply unit;

• radiation source.

Control console and power supply unit are interconnected by 50 m cable for ING-07 generator and up to 1000 m for ING-17, and power supply unit and radiation source - by 5 m cable.

The ING-07 special feature is presence of microprocessor system to control mode for powering neutron tube, that allows high (not less 95%) stability of neutron output within all range from 5× 10⁷ to 1× 10⁹ n/s and also the generator interconnection with computerized measuring stations through serial interface RS-232.

These generators (Table 1) include power supply and control unit and radiation source. The power supply and control unit and radiation source are in metallic cylindrical bodies and interconnected by threaded connection. The generators are powered from 200 Vdc.

VNIIA neutron generators are dual-use products, so their delivery requires export license. We need from customer the international import certificate and signed contract for delivery of chosen products for the export license issue. The license issue takes 4-5 months. So, an order should be executed within 6-9 months from its receipt depending on individual generator. The specified prices include delivery cost and may be changed during negotiations on contract. The generators using (D-D) tube may be delivered at customer request. Such the generators provide 2,5 MeV neutron yield approximately 2 orders less than (D-T) generators.
