1Development of the CAS-LIBB single-particlemicrobeam for localizedirradiation of living cells显示文摘A single-particle microbeam facility has been constructed at the Key Laboratory of Ion Beam Bioengi- neering (LIBB), Chinese Academy of Sciences (CAS). The system was designed to deliver a defined numbers of hydro- gen ions, produced by a van de Graaff accelerator, in an en- ergy range of 2.0—3.0 MeV, into an area smaller than that of the nucleus of an individual living cell. The beam is colli- mated by a borosilicate glass capillary that forms the beam-line exit. An integrated computer program recognizes the cells and locates them one by one over the microbeam exit for irradiation. We present technical details of the CAS-LIBB microbeam facility, particularly on the collimator, hardware, control program, as well as cell irradiation proto- cols available. Various factors contributing to the targeting and positioning precision are discussed along with accuracy measurement results.WANGXufei WANGXiaohua CHENLianyun HUZhiwen LIJun WUYu CHENBin HUSuhua ZHANGJun XUMingliang WULijun WANGShaohu FENGHuiyun ZHANFuru PENGShixiang HUChundong ZHANGShuqing CHENGJianjun SHIZhongtao YUANHang YUANHaitao YUZengliang 2004Chinese Science Bulletin2004,49,17:5
