The Tandem Electrostatic Accelerator
The tandem accelerator is a model 25 URC accelerator built to ORNL specifications
by the National Electrostatics Corporation (NEC). The high-voltage
generator, located inside a 100-ft-high, 33-ft-diameter pressure vessel,
has been built in a folded configuration with both low- and high-energy
acceleration tubes contained within the same column structure. Reversal
of ion direction in the high-voltage terminal is provided by a 180 degree
magnet which also serves to prevent ions of unwanted charge state from
being introduced into the high-energy acceleration tube. The insulating
gas used for the tandem is pure SF6. Typical operating pressure is
between 65 and 80 psig. Today, the tandem accelerator provides acceleration
for radioactive ion beams (RIBs) produced from the RIB injector.
