Detectors which were irradiated during these experiments included the NASDA RRMD-III, the IV-CPDS, ISS-TEPC and Shuttle-TEPC from NASA-JSC, the U. of Kiel DOSTELs, the Liulin-4J of STIL-BAS and NIRS and a number of passive detectors. Since several of these detectors had not been previously irradiated to high energy heavy ion beams, the ICCHIBAN-1 and 3 exposures were the first attempts to systematically investigate their response in the high LET region. These experiments are significant for space radiation dosimetry because not only silicon detectors but also two tissue equivalent proportional counters were included. Based on the participants reports for the ICCHIBAN-1 experiment, we have compared the results from the different instruments. This comparison, together with initial results from the ICCHIBAN-3 experiment, will be presented. In addition, information regarding the 5th ICCHIBAN experiment will be announced., 8th WRMISS Workshop}, title = {Comparison of results from the 1st ICCHIBAN experiment and current status of the 3rd ICCHIBAN Experiment}, year = {2003} }
