E!11654, ENEFRF, Energy Efficient PET Cancer Diagnostics: Novel RF Source for Radioisotope Production

Reference number
Coordinator Comheat Microwave AB
Funding from Vinnova SEK 5 000 000
Project duration November 2017 - January 2022
Status Ongoing
Venture Eurostars

Purpose and goal

Develop the next generation RF-source for isotope producing cyclotrons, supplying the industry with the newest RF power Solid State Amplifier technology and transistors.

Expected results and effects

The research at Uppsala University in the field of high power solid state RF amplifiers will be used by Swedish and EU industry. The University will focus on the useful research topics for the industry. Comheat AB is developing further its breakthrough LDMOS transistor’ technology and ensures its commercialization. Ampegon AG industrializes the prototype amplifiers realized within the project, in a business relationship with GE. GE will improve further its market share in the cyclotron business relying on the latest high power solid state RF amplifiers and semiconductor technology.

Planned approach and implementation

The ENEFRF project spans over a period of 3 years with a total budget of 19.6 MSEK and targets several R&D topics of high interest for the industry: (1) development of highly efficient RF power amplifiers at 27 and 101 MHz (2) development of highly efficient RF power combiners at power levels of 10 and 100 kW (3) development of digital waveform generation for RF power amplifiers (4) characterization of new transistors, involving load pull measurements. Other aspects related to the reliability of high power transistors, thermal behaviour and lifetime will also be investigated.
