"High Average Brilliance Compact Inverse Compton Light Source"
Kirsten E. Deitrick
Old Dominion University
Abstract: There exists an increasing demand for compact Inverse
Compton Light Sources (ICLS) which are capable of providing
substantial fluxes of narrow-band X-rays. Currently, multiple
design proposals have been made. Compared to a typical bremsstrahlung
source, most of these designs have comparable fluxes and improve on
the brilliance within a 0.1% bandwidth by only few orders of magnitude.
By applying cw superconducting rf beam acceleration and focusing to
generate a beam spot size at collision at the several micron level,
the source presented here provides a 12 keV X-ray beam with a flux of
1014 ph/s and an average brilliance of 1015 ph/(s-mm2-mrad2-0.1%BW).
Compared to a bremsstrahlung source, this improves the flux by at least
an order of magnitude and the average brilliance by six orders of
magnitude. Surpassing other compact ICLS designs, the source presented
here is attractive to a wide variety of potential users.
