Focal spot size predictions for beam transport through a gas-filled reactor Page: 3 of 12

S. S. Yu, E. P. Lee, and H. L. Buchanan
Results from calculations of focal spot size for beam transport
through a gas-filled reactor are summarized. In the converging beam mode,
we find an enlargement of the focal spot due to multiple scattering and
zeroth order self-field effects. This enlargement can be minimized by
maintaining small reactors together with a careful choice of the gaseous
medium. The self-focused mode, on the other hand, is relatively insensitive
to the reactor environment, but is critically dependent upon initial beam
quality. This requirement on beam quality can be significantly eased by the
injection of an electron beam of modest current from the opposite wall.
