An Experiment to Simulate the Trapping and Detection of Radioactive Isotopes Produced In ICF Implosions
Christensen, Micah J.
It may be possible to measure the low energy nuclear cross sections of light ion reactions by trapping the reaction products from an ICF implosion and detecting their beta decays. To test this idea, an “exploding wire” experiment has been designed to simulate the expanding gas released in an ICF event. A copper plated tungsten foil was inserted into a vacuum chamber and activated with a deuteron beam via 65Cu(d,p)66Cu. A current pulse then vaporized the copper to create an expanding radioactive gas, simulating the gas behavior in the ICF target chamber following the laser shot. Attempts were made to capture some gas and detect the 66Cu beta decays using two trap designs, one using a getter foil and the other a turbopump. Results were obtained with both trap designs, using the Short-Lived Isotope Counting System (SLICS) consisting of plastic scintillator phoswich detectors and fast electronics to identify and count the beta particles.
