tube. e ion beam is extracted from a 3mm diameter aperture and acceler-
ated to a target at 100 kV. e target is water-cooled and is made of explosive-
bonded titanium-on-aluminum material.
e axial neutron generator is mainly used in pulsed mode experiments. e
pulsing is performed by switching the RF power on and o. e current RF
power supply is limited in pulse length of 2 ms. e rise time of the plasma can
be as short as a few microseconds, which is achievable using a fast rise-time RF
generator. e compact axial extraction neutron generator is constantly being
evacuated by a turbo molecular pump. is is possible because no radioactive
tritium gas is used. Some applications of the neutron generator require port ...
