Control of the detection threshold of CR-39 PNTD for measuring ultra heavy nuclei in galactic cosmic rays

It is necessary to develop a track detector with higher detection threshold and high charge resolution for ultra heavy cosmic ray observation. The track registration sensitivity in CR-39 track detector etched by PEW (Potassium–Ethanol–Water) solution was verified using heavy ion beams at the HIMAC a...
