Best 70p Cyclotron

 
The Best 70p is a 70 MeV proton cyclotron.  The energy provides access to radionuclides produced by (p,xn) reactions and is a research accelerator as well as a radioisotope production cyclotron.  TeamBest^® will partner with the end user to create a facility that will satisfy the end user's requirements and provide some of TeamBest's radioisotope supply requirements, together with the opportunity for joint research projects.  Both solid and gas target systems can be added to the Best 70p system.
 

External Production Targets

The cyclotron is supplied with high current solid target stations and high current gas target stations.
