FIELD: electricity.SUBSTANCE: device includes a source of ions placed under pressure in the medium containing an ionisable gas. The source of ions includes substrate with a bundle of carbon nanotubes passing away from it. Ends of nanotubes are spaced apart with a grate. Voltage supply electronic circuit provides gas ionisation and ion emission through the grate. Ion accelerator section is located between the source of ions and the target. Ion accelerator section accelerates ions passing through the grate to the target, so ion-target collision stipulates generation and emission of neutrons from it. The source of ions, accelerator section and target are placed in a sealed tube and carbon nanotubes in a bundle should be perfectly ordered preferably with at least 10of carbon nanotubes per cmpassing in direction parallel in essence to the central axial line of the tube.EFFECT: creating gas ionisation with high atom-molecule ratio thus ensuring creation of compact small-sized samples suitable for logging tools.16 cl, 2 dwg |
