Abstract:
A dedicated booster synchrotron is being
constructed at the Duke FEL Laboratory to
provide full energy injection into the main
electron storage ring. A new timing system
has been developed to coordinate the
injection of electron bunches from the linac
to the booster, the ramping of energy in the
booster, and extraction of bunches into the
main ring. The timing system will allow the
extraction of any bunch in the booster into
any selected bucket in the main ring to
provide top-off injection for any of the
various operational bunch patterns of the
main ring. A new master oscillator has also
been developed for the RF system of the
booster. The oscillator may be tuned
independently or phase-locked to the master
oscillator of the main ring. The issues of
the soft phase locking process of the new
master oscillator are discussed. The timing
system and new oscillator have been
fabricated and tested and are ready for
operation.
