High
efficiency radio frequency (RF) power sources are
needed in the frequency range 300-1500 MHz because they are essential for the
operation of high-power particle accelerators for nuclear physics
research. Applications include the
Continuous Electron Beam Accelerator Facility (CEBAF) at Thomas Jefferson National
Accelerator Laboratory (JLab), the Relativistic Heavy
Ion Collider (RHIC) and Electron-Ion Collider (eRHIC) at Brookhaven
National Laboratory (BNL), the Rare Isotope Accelerator (RIA) at Argonne
National Laboratory (ANL), and the Spallation Neutron
Source (SNS) at Oak Ridge National Laboratory (ORNL). At present, conventional circular-beam
klystrons are the technology of choice for high-power accelerators. However, they are not efficient when
operating at high-power and low beam voltages, conditions that are required for
continuous-wave (CW) high-power. This
project will develop an innovative elliptic beam klystron, using proprietary
elliptic electron beam technology, which will meet the requirement for a 1 MW cw RF power source at 704 MHz. An efficiency of 75% is possible with the
elliptic beam interaction.
Commercial
Applications and other Benefits as described by the awardee: An
elliptic beam klystron not only would be a significant technical achievement,
but also would replace conventional klystrons in the commercial marketplace,
which has annual sales of $200M worldwide.
