Abstract. A systems study, including physics, engineering and costing, has been
conducted to assess the feasibility of a relativistic-klystron two-beam-accelerator (RK-
TBA) system as a RF power source candidate for a 1 TeV linear collider. Several key
issues associated with a realizable RK-TBA system have been addressed, and
corresponding schemes have been developed and examined quantitatively. A point
design example has been constructed to present a concrete conceptual design which has
acceptable transverse and longitudinal beam stability properties. The overall efficiency
of RF production for such a power source is estimated to be 36%, and the cost of the
full system is estimated to be less than 1 billion dollars.
1.1 TBA Issues
As a power source for linear colliders. The main advantage of two-beam-
accelerator (1) is high efficiency for drive-beam to rf power conversion.
Experimentally, very high peak powers have been achieved in free-electron-laser
(2) and relativistic-klystron (3) devices. The basic concept of reacceleration was
demonstrated in recent experiments at LLNL (4).
These experimental successors not withstanding, several critical issues must
be addressed if two-beam accelerators are to be viable as practical power sources
for future linear colliders.
The general concerns about relativistic-klystron two-beam accelerators (5)
(RK-TBA) as a realizable power source evolve around 3 issues:
