High Power targets for Isotope Production

Development of solid and liquid targets, for improved output in terms of activity, radiochemical speciation and specific activity.

At Hevesy lab we have a special commitment to the development of solid and liquid targets, for improved output in terms of activity, radiochemical speciation and specific activity. We have raised the available proton beam from our GE PETtrace cyclotron from the specified 80 microAmp to over 200 microAmp, giving 3.3 kW beam power to the target. We have now a solid target ( for radio-metals like Cu-64) capable of standing this power. We are still struggling to find a way to make F-18 with 200 microAmps. Of special interest in the development of targetry for istope productions are the development of diagnostic methods, both to monitor actual, in-beam production rates, but also for optimising beam quality. Beam quality can have a strong influence on the radiochemical availability of the radioisotope. This work is pursued as part of an international collaboration under IAEA.

One important goal is a reliable beam profile monitor, rapidly and remotely insertable and capable of withstanding full beam. Various “glowing mesh” approaches have been tested with some success, while the standard rotating helical wire scanner fails at or beam currents.
