Results obtained with the passive radiation detectors in the ICCHIBAN-4 experiment

Abstract

In frame of the InterComparison of Cosmic rays with Heavy Ions Beams at NIRS (ICCHIBAN) organized at the HIMAC accelerator in Chiba several types of the thermoluminescent detectors (TLD), as well as CR-39 track detectors, were exposed. Four different types of TLDs were used: MTS-7 (7LiF:Mg,Ti), MTS-6 (6LiF:Mg,Ti), MCP-7 (7LiF:Mg,Cu,P) and MTT-7 (7LiF:Mg,Ti with changed activator composition. All TLDs were manufactured at the Institute of Nuclear Physics (IFJ) in Krakow. The detectors were irradiated with various doses of He, C, Ne and Fe ions. Part of exposures were done in unknown conditions, to test measuring capabilities of the detectors. For analyses of these results, the method of obtaining information on ionisation density of an unknown radiation field, which is based on ratios of responses of different LiF detectors, was successfully used.
