Routine production of copper-64 using 11.7MeV protons
- Conference date: 26–29 August 2012
- Location: Playa del Carmen, México
Reliable production of copper-64 ( ) was achieved by irradiating enriched nickel-64 ( , >94.8%) in an IBA 18/9 cyclotron. Nickel-64 (19.1 ± 3.0 mg) was electroplated onto an Au disc (125μm × 15mm). Targets were irradiated with 11.7 MeV protons for 2 hours at 40μA. Copper isotopes ( ) were separated from target nickel and cobalt isotopes ( ) using a single ion exchange column, eluted with varying concentration of low HCl alcohol solutions. The target material was recovered and reused. The production rate was (with a maximum of 2.6GBq of isolated after 2hr irradiation at 40uA. Radionuclidic purity of the was 98.7 ± 1.6 % at end of separation. Cu content was < 6mg/L (n = 21). The specific activity of was determined by ICP-MS and by titration with Diamsar to be and , respectively; which are in agreement, however, further work is required.
