Dear WRMISS and ICCHIBAN participants,
We are pleased to announce the 4th ICCHIBAN experiment scheduled for May 20003 at the NIRS HIMAC. This experiment will be devoted to intercomparison of the response of passive detectors used for crew and area dosimetery aboard spacecraft. The following is the schedule of beam time:
May 19, C 400 MeV/n
May 21, Ne 400 MeV/n
May 24, He 150 MeV/n
May 29, Fe 500 MeV/n
The ICCHIBAN-4 experiment will be a logical follow-on to last year's ICCHIBAN-2 experiment. We plan to carry out 6 known (for each ion) and 8 blind exposures (Totally, 32(!) + control + spare detector packages are required.) and we may include not only heavy ions, but also Co-60 gamma ray exposures in the blind exposures. The exact required number of detectors will be announced soon.
If you plan to participate in the ICCHIBAN-4 experiment, please let us know immediately. In addition, please tell us the number and types of different passive detectors you'd like to include, e.g. TLD and CR-39 PNTD. As with last year's ICCHIBAN-2 experiment, you do not have to be present at HIMAC to participate. You may send your detectors directly to Yukio Uchihori at NIRS and we will expose them for you. Your detectors should arrive at NIRS no later than 10 May 2003.
We are also planning to carry out the first Proton ICCHIBAN experiment later this year at Loma Linda University Medical Center. The Proton ICCHIBAN experiment is scheduled to coincide with the WRMISS meeting in Berkeley in September. However, the precise dates of the Proton ICCHIBAN experiment have not yet been finalized. We will provide you with this information as soon as it is available to us.
With best regards,
Yukio Uchihori, Eric Benton, and the ICCHIBAN Working Group
