| Abstract: | Electron
accelerators from 500 keV to 10 MeV energy are employed for surface
irradiation, food preservation, medical sterilization, cargo scanning and other
industrial products. At EBC, a 10 MeV Linac has been indigenously developed and
is operational for radiation processing. This is an on-axis coupled cavity
standing wave type of RF linac
operating with
50-70 keV electron gun having LaB6 cathode and klystron-based RF source at 2856 MHz. The linac is
currently operating at 10 MeV, 130 mA (peak), 10 µs pulses at a prf of 415 Hz
and is employed for various experiments. A similar 9 MeV linac is operational
for cargo-scanning. A compact 6 MeV linac is under development. A 500 keV, 3 kW
dc accelerator based on Cockroft
Walton multiplier has been operational for industrial surface processing. A 3
MeV dc accelerator based on parallel
coupled multiplier column is operational at 1 MeV, 4.6 kW level. A 700 keV, 5
kW dc machine for cross-linking and
graft polymerization is under development. A 100 MeV, 100 kW electron Linac for
producing intense neutron source has been proposed for development.
Technological developments, operating experiences, utilization for industrial
applications and safety aspects of all facilities are described. |
