Operation status of K-600 Cockraft-walton generator and other task

In 1990, the K-600 neutron generator was operated for 600 hours as follows: 1) It took 160 hours to provide neutron beams to irradiate wheat seeds for the Academy of Agricultural Sciences of Gansu province and the Institute of District Agricultural Sciences. 2) It took 100 hours to provide D2 beam for the microelement analysis of Al2O3 electrolyte produced by the Gansu Aluminium Factory. 3). It took about 100 hours to provide D2 beam for the analysis of elemental components of soil micro-fertilizer from other provinces. The D2 beam is 2 mA and the neutron intensity is 2 x 1011 n/s. 4). It took 50 hours to operate the generator for analysing O3 concentration measured in air by the radiation protection group. The value of high voltage is 450 kV. 5). In order to measure the transferable collection efficiency of melting target system in the institute, the authors spent 200 hours for operating the generator. The neutron intensity is >1011 n/s
