| Research Abstract |
A PID-TEPC which consist of tissue equivalent proportional counter(TEPC) and solid state detector(SSD) system was improved and tested. The SSDs were changed from 500μm to 700μm to improve the particle identification resolution. This system was tested with spread out Bragg peak(SOBP) carbon beam. Microdosimetric spectra of fragment particles were measured by this system. As the result of this test, microdosimetric spectra of proton, helium, lithium, beryllium, boron, carbon and neutron could be obtained separately. Neutron component obtained by this system was higher than that produced in a body simulated phantom by mono-energy carbon beam. Therefore, neutron energy spectrum produced in SOBP beam moderator has been also measured.
