A. Schempp, INCREASING THE EFFECTIVE LINAC CURRENT BY POSTFUNNELING, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 415(1-2), 1998, pp. 402-404
The linac emittance and current are limiting factors for the phase- sp
ace density and ion beam current for the multiturn injection into the
storage ring of a HIIF driver. Chopping and Funneling sections shape t
he beam to match the beam to the storage rings. A system is described,
which can double the effective ion current of the linac and the bunch
charge in the storage ring without changing the basic linac parameter
s by an additional funneling stage. (C) 1998 Elsevier Science B.V. All
