The Next Generation Linear Collider (NLC)
will require 800 klystron modulators capable of providing 500 kV, 500 A pulses
at 120 Hz. The losses and non-ideal
pulse characteristics inherent in currently available pulse transformers are a
significant impediment to high performance, highly efficient modulator systems.
Further, modulator inefficiencies translate directly into
increased operating costs. This
project will design, build, and assess a toroidal, low impedance pulse
transformer for the NLC klystron modulators, which significantly improves on
available designs. Multiple
full-scale designs will be constructed and tested with existing switch
technologies, including a solid state switch.
Phase I will model, design, and prototype a scaled toroidal pulse
transformer architecture capable of achieving the desired NLC modulator
requirements and efficiency. The
design will be assessed for cost, efficiency, and reliability within a NLC
klystron modulator. A full-scale,
very high power, pulse transformer will be constructed in Phase II.
Commercial Applications And Other Benefits as described by awardee: Pulsed power systems are increasingly important to new materials modification and treatment processes, such as plasma source ion implantation. Cost effective, very high peak power systems may enable the development of new manufacturing and materials processing techniques across a wide range of industrial and medical applications, including semiconductor fabrication, medical treatment systems, radar, and food sterilization.
