Description
The Distributed-Drive Linac (DDL) concept allows independent control of the radiofrequency (RF) power and phase of each accelerator cell, realized by an RF power system consisting of discrete solid-state amplifiers (SSAs). The DDL concept is under investigation at Los Alamos Neutron Science Center (LANSCE) as a candidate for the future upgrade of the 805-MHz Coupled-Cavity Linac. Independently adjustable RF power and phase of each DDL accelerator cell allows using the same DDL architecture to provide a much higher beam energy at the linac exit, such as 2-3 GeV, for proton radiography (pRad). The DDL architecture would require significant upgrade of the RF infrastructure at LANSCE, including implementing a great number of phase-coherent coaxial transmission lines for 3000-5000 individual DDL accelerator cells. For the pRad operation mode, compact RF pulse compressors are also under investigation.
