Experimental studies on debris collection for radiochemistry in inertial confinement fusion

We report several experimental results on debris collection for radiochemistry in inertial confinement fusion research. The collection efficiency was measured by means of radioactive tracers 24 Na, 82 Br, 152m1 Eu and activatable tracer 151 Eu in glass or plastic shells. It is shown that the collection efficiency depends on the atomic weight of the tracer and the surface condition of the collector, and does not greatly depend on the initial areal density of the target, in our experimental conditions.
