From: First on-line detection of radioactive fission isotopes produced by laser-accelerated protons
Experimental setup. The produced protons from TNSA enter the uranium-target container through a titanium window. RCFs located in front and behind the uranium-target container measure the proton spectrum. The fission products are stopped by a gas mixture of helium and argon in the same mass flow proportion and transported to a carbon filter \(12 \, \hbox {m}\) away outside the PHELIX target chamber. The various \(\upgamma\)-lines from the transported isotopes are measured with a HPGe detector.
