Production of pharmaceutical grade [Tl]Thallous chloride using 30 MeV cyclotron.

Multiple patient doses of [Tl]TlCl has been produced using electrodeposited enriched Tl in 30 MeV cyclotron (Cyclone-30) with 28 MeV proton energy at 50 μA beam current for 8 h. Ion Exchange Column Chromatography (IECC) and liquid-liquid extraction has been employed for semi-automated radiochemical separation and purification of produced [Tl]TlCl. The produced [Tl]TlCl was used in coronary artery disease (CAD) patients.

Development and characterization of a high yield transportable pulsed neutron source with efficient and compact pulsed power system.

The results of characterization experiments carried out on a newly developed dense plasma focus device based intense pulsed neutron source with efficient and compact pulsed power system are reported. Its high current sealed pseudospark switch based low inductance capacitor bank with maximum stored energy of ∼10 kJ is segregated into four modules of ∼2.5 kJ each and it cumulatively delivers peak current in the range of 400 kA-600 kA (corresponding to charging voltage range of 14 kV-18 kV) in a quarter time period of ∼2 μs.
