Up to now 11C6+ ion beam has been tried with very limited intensities of ~10E5 per pulse created with a nuclear reaction of 12C6+ ion beams accelerated by HIMAC (so-called “Projectile Fragment Separation Scheme”) and it was not possible to attain good enough signal to noise ratio to obtain a diagnosable imaging. Recently the usage of 11C ion beam, produced by irradiation of a high intensity proton beam coming from a cyclotron has been investigated. For this purpose, we have studied the separation of the molecular 11CO2+ ion beam from the overwhelming 12CO2+ ion beam with the use of a double focusing magnet. The design of the double focusing magnet as well as the scheme to supply 11C4+ radioactive ions to HIMAC Injector to re-accelerate for cancer therapy is to be presented.}, pages = {1195--1197}, title = {放射性11C+イオンビームの質量分離のための二重集束電磁石の設計}, year = {2018} }
