| Summary: | One electrostatic accelerator based compact neutron generator was developed.
The deuterium ions generated by the ion source were accelerated by one
accelerating gap after the extraction from the ion source and bombarded to a
target. Two different types of targets, the drive - in titanium target and
the deuteriated titanium target were used. The neutron generator was operated
at the ion source discharge potential at +Ve 1 kV that generates the
deuterium ion current of 200 mA at the target while accelerated through a
negative potential of 80 kV in the vacuum at 1.3×10-2 Pa filled with
deuterium gas. A comparative study for the neutron yield with both the
targets was carried out. The neutron flux measurement was done by the bubble
detectors purchased from Bubble Technology Industries. The number of bubbles
formed in the detector is the direct measurement of the total energy
deposited in the detector. By counting the number of bubbles the total dose
was estimated. With the help of the ICRP-74 neutron flux to dose equivalent
rate conversion factors and the solid angle covered by the detector, the
total neutron flux was calculated. In this presentation the operation of the
generator, neutron detection by bubble detector and estimation of neutron
flux has been discussed.
