Production of Radioisotopes in the ORNL 86-Inch Cyclotron

Simultaneous production and quality control of 73Se and 75Se radioisotopes in a 30 MeV cyclotron

Background : Selenium-73 (T 1/2 =7.1h) and Selenium-75 (T 1/2 =119.8d) are useful radioisotopes in many research fields. The wide ranges of applications of these radioisotopes arose great interest for their production. Simultaneous production of 73 Se and 75 Se is more cost-effective and less time-consuming. Materials and Methods : 73 As (p, 3n) 73 Se and 75 As (p,n) 75 Se reactions were determ...

Operational Performance of the Lbl 88-inch Cyclotron

The 88-Inch Cyclotron began regular operation with the ECR (Electron Cyclotron Resonance) source in January 1985. Since then about 80% of the cyclotron operating schedule has been with the ECR source. The light-ion filament source is used only for runs two or more shifts in length using proton, deuteron, 3He, or alpha beams. Occasionally the polarized ion source is used. The heavy-ion PIG sourc...

High Intensity Ion Beam Injection into the 88-inch Cyclotron

Low cross section experiments to produce super-heavy elements have increased the demand for high intensity heavy ion beams at energies of about 5 MeV/nucleon at the 88-Inch Cyclotron at the Lawrence Berkeley National Laboratory. Therefore, efforts are underway to increase the overall ion beam transmission through the axial injection line and the cyclotron. The ion beam emittance has been measur...
