Testing natural and synthetic micas as detectors of accelerated heavy ions

In the Laboratory of Elementary Particles of the LPI the dielectric materials are being tested as detectors of fission fragments of superheavy nuclei in the thermochromatographic column of the JINR Superheavy Elements Factory. In the paper, the results of testing various micas irradiated with accelerated Xe and Bi ions with energies from 83 to 670 MeV are analyzed. It is shown that two types of natural mica retain ion tracks when heated after irradiation up to 300 and 500$^\circ$C, which means their fundamental applicability in experiments studying the properties of superheavy nuclei.
