Proton beams accelerated by an RFQ and a DTL with resonant frequency of 433 MHz,are electron cooled after injection into a storage ring, S-LSR and fast extracted to a beam irradiation target. Short pulse duration around 3.5 ns is expected for the 7 MeV proton beam with the intensity of 1.4 x 108 [1]. This beam is to be utilized for irradiation of biological cells in order to investigate Radio Biological Effectiveness of proton beam with a very high peak intensity for the purpose of quantitative verification of the recent report on the DNA double strand breaking with the use of short-pulse laser-produced proton beam [2]
