Title: Electron cyclotron resonance ion source experience at the Heidelberg Ion Beam Therapy Center. Author: Winkelmann T, Cee R, Haberer T, Naas B, Peters A, Scheloske S, Spädtke P, Tinschert K. Journal: Rev Sci Instrum; 2008 Feb; 79(2 Pt 2):02A331. PubMed ID: 18315121. Abstract: Radiotherapy with heavy ions is an upcoming cancer treatment method with to date unparalleled precision. It associates higher control rates particularly for radiation resistant tumor species with reduced adverse effects compared to conventional photon therapy. The accelerator beam lines and structures of the Heidelberg Ion Beam Therapy Center (HIT) have been designed under the leadership of GSI, Darmstadt with contributions of the IAP Frankfurt. Currently, the accelerator is under commissioning, while the injector linac has been completed. When the patient treatment begins in 2008, HIT will be the first medical heavy ion accelerator in Europe. This presentation will provide an overview about the project, with special attention given to the 14.5 GHz electron cyclotron resonance (ECR) ion sources in operation with carbon, hydrogen, helium, and oxygen, and the experience of one year of continuous operation. It also displays examples for beam emittances, measured in the low energy beam transport. In addition to the outlook of further developments at the ECR ion sources for a continuously stable operation, this paper focuses on some of the technical processings of the past year.[Abstract] [Full Text] [Related] [New Search]
