RF power units

From a pure high voltage pulse modulator all the way to a turn-key RF unit

As one of the few players in the market, ScandiNova has the capability to offer a complete optimized RF system. The integration of subsystems and components is made with the skills earned through our background in the accelerator industry and make the use of these RF systems adapted to the needs of the RF engineer. 

ScandiNova integrates sets of subsystems, such as focusing solenoid power supplies, vacuum power supplies, RF amplifiers, directional couplers etc and controls them with our specially designed control system ScandiCAT™. The table below shows the possible RF configuration for a Klystron pulse modulator system. We also provide turn-key Magnetron pulse modulator systems based on your needs. 

Partners: Toshiba, Thales Group, Communications & Power Industries (CPI) 

Our well-working collaboration with leading suppliers and partners secures a robust solution that meets the high market demands.

Functional Description 

The CCPS is the main power source of the system. It converts the input AC mains power to a regulated DC voltage around 1000VDC. This DC Voltage is used to charge the Switch Unit. A trigger pulse gates all the Solid State switches in the Switch Unit and discharges the stored energy until the required pulse length is obtained. The switches are then turned off. 

This produces a primary pulse to the Pulse Transformer which transforms the voltage to the right level for the Load (i.e. Klystron, Magnetron, E-gun, PEF-load etc). 

All parts of the modulator are located inside a common enclosure, but only the pulse transformer and the load HV interface are surrounded by transformer oil inside a sealed tank. All essential electronics and parts such as the CCPS, Switching Units and Control System are all in air and therefore easily accessible.

World-leaders put their trust in our skills

Organizations who have put their trust in our expertise include the European Extreme Light Infrastructure Nuclear Physics (ELI-NP) laboratory, the Maxlab electron accelerator laboratory for synchrotron radiation research, nuclear physics and accelerator physics, and Advanced Oncotherapy, where our modulators comprise a key part of the company’s particle therapy system for cancer treatment.
