A compact neutron generator tube that is intermediate in yield and size between radioactive sources and previous laboratory neutron sources was developed. Design requirements of long life, low power, portability, and operational simplicity were demonstrated in construction and test of more than 500 tubes. Applied power of 25 to 30 watts produced more than 10/sup 8/ neutrons/sec in either continuous or pulsed operation at temperatures as great as l45 deg C and for periods longer than 100 hr. The tube contains a coldcathode ion source, a close-spaced accelerating electrode geometry, a metal hydride for gas pressure control, and an impacted target continuously replenished by a mixedisotope ion beam. Life tests indicated that the average tube could be operated for more than 200 hr at a yield of 10/sup 8/ neutrons/sec. (M.C.G.)
