50 kW CW MULTI-BEAM KLYSTRON (MBK)

microwave power sources (such as klystrons) offering an increased efficiency (80% or above) are needed for various applications- Of a particular interest is a source at 952-6 MHz delivering 50kW (continuous) CW for the RF systems for ion acceleration in the Energy Electron Ion Collider EIC being developed at Thomas Jefferson National Accelerator Facility- A novel tube (klystron) concept with efficiency in excess of 80%, delivering 50 kW CW at 952-6 MHz MHz is proposed- It is a combination of proven technologies put together: its uses multiple beams to have its perveance low to boost beam-power to RF efficiency- It uses a partially grounded depressed collector (as invented by Omega P R&D) with a carefully tailored beam distribution after the cavity chain to recover energy thereby increasing the overall efficiency even more- A low operating voltage makes the tube more user-friendly avoiding need for costly modulators and oil insulation- A sectioned solenoid is used to insure superb beam-matching to all components downstream of the electron gun, increasing the tube performances-
