Description
The design of High Power Amplifiers for an energy upgrade to 12 GeV is underway at Jefferson Lab. Eighty 13 kW 1.497 GHz amplifiers with required power supplies and waveguide components will be added to the existing accelerator, expanding on the 340 5 kW sockets. Klystrons and IOTs are being considered, with each having advantages and disadvantages.
While JLab’s 340 5 kW klystrons have proven reliable over the past 18 years, the device’s overall efficiency is low. With energy deregulation and subsequent increasing costs, options to reduce energy consumption were evaluated. Changes to operating modes and replacement of the present klystron with a higher efficiency device were considered. To be cost effective, any replacement klystron or IOT would need to be priced right and be adaptable to the existing hardware with minimal modifications to existing equipment. The outcome is that no changes are planned at this time.
