✦ Synopsis

The variation of track response with registration temperature for Uranium ions in solid state nuclear track detectors has been investigated for the first time. Preliminary results are presented for Tuffak polycarbonate, Lexan polycarbonate and three types of doped CR-39 detectors exposed to 960 MeV/N Uranium beams at registration temperatures of -78°C and +18°C. The fractional change in signal strength (VT) per °C was found to be considerably greater than that for nuclei of lower ionisation. This result has very significant implications for future ultra heavy cosmic ray experiments employing solid state nuclear track detectors.

In addition, it can explain apparent anomalies in the data of previous ultra heavy cosmic ray experiments.
