The Next Generation Linear Collider (NLC) requires
significant numbers of klystrons and pulsed power supplies for operation.
However, the baseline klystron design requires pulsing at 500 kV, which leads to
significant losses in the pulsed power supplies, losses that would represent $10
million or more in annual electricity costs during the NLC life. A gridded
sheetbeam klystron alternative to the baseline klystron, which eliminates the
500 kV pulsing and associated power losses, is now under development. This
design separates the power systems and klystrons through a long, specialized
cable – reducing the costs of constructing and operating the NLC. To implement this sheet beam klystron design, a complex
klystron power system will be needed, capable of providing 500 kV cathode power
and very fast, highly accurate grid pulses over a long, specialized cable. This
project will develop the required high voltage power supplies, grid pulser, and
other electronics needed to drive the sheet beam klystron over a long cable. Phase
I designed the complete power supply, suitable for construction, testing, and
integration into a full sheet beam klystron demonstration in Phase II.
Phase II will coordinate the requirements and design of the power
electronics with a high voltage cable design and a gridded sheet beam klystron
(both under separate development) to ensure that the entire system design is
consistent across all three subsystems. Then,
each element of the electronics, including the multiplier power supply, grid
pulser, and controls will be built and tested to ensure they meet
specifications.
Commercial Applications and Other
Benefits
as described by awardee: The
primary benefit would be a large reduction in the operational costs of the Next
Generation Linear Collider. Beyond the NLC, there are thousands of industrial
and medical accelerators that could receive the same types of benefits from
adoption of the sheetbeam klystron.
