The
Next Generation Linear Collider (NLC) requires significant numbers of klystrons
and pulsed power supplies for operation. The
baseline klystron design requires pulsing at 500 kV, which leads to significant
losses in the pulsed power supplies, representing $40 – $100 million or more
in electricity costs over a 10 year NLC life.
A gridded sheetbeam klystron that eliminates the 500 kV pulsing and
associated power losses is being developed as an alternative to this baseline
klystron. However, the new klystron
will require a fundamentally new approach to powering the sheetbeam klystrons,
one that places significant demands on the two hundred foot cable that is
envisioned to connect the power supplies and fast grid pulsers to the klystrons.
This project will develop high voltage cables that will meet the NLC
sheetbeam klystron requirements and be affordable in the large quantities
required for construction of the NLC itself.
Phase I conducted the required analyses and tradeoffs of the cable and
connector design, materials, construction methods, and performance to arrive at
a manufacturable cable design. Phase II will iterate and finalize the
cable design, and manufacture representative samples. These
cables will be tested and assessed for performance, reliability, and cost, and a
cable design will be selected for full scale prototyping.
Commercial Applications and Other
Benefits
as described by awardee: The
new cable should contribute to a large reduction in the operational costs of the
Next Generation Linear Collider. At
the same time, this design would enable a more cost-effective physical
configuration of the NLC power system, thereby, reducing construction and
maintenance costs. Beyond the NLC, thousands of industrial and medical
accelerators could benefit from adopting the sheetbeam klystron, which would
utilize the new cable technology.
