Long-term Operation Experience with Two Ecr Ion Sources and Planned Extensions at Hit
نویسندگان
چکیده
The HIT (Heidelberg Ion Beam Therapy Center) is the first treatment facility at a hospital in Europe where patients can be treated with protons and carbon ions. Since the commissioning starting in 2006 two 14.5 GHz electron cyclotron resonance ion sources are routinely used to produce a variety of ion beams from protons up to oxygen. The operating time is 330 days per year, our experience after three years of continuous operation will be presented. In the future a helium beam for patient treatment is requested, therefore a third ion source will be integrated. This third ECR source with a newly designed extraction system and a spectrometer line will be installed at a testbench to commission and validate this section. Different test settings are foreseen to study helium operation as well as enhanced parameter sets for proton and carbon beams in combination with a modified beam transport line for higher transmission efficiency. An outlook to the possible integration scheme of the new ion source into the production facility will be discussed.

Experience at the Ion Beam Therapy Center (hit) with 2 Years of Continuous Ecr Ion Source Operation
Radiotherapy with heavy ions is an upcoming cancer treatment method with to date unachieved precision. It associates higher control rates particularly for radiation resistant tumour species with reduced adverse effects compared to conventional photon therapy. This paper will provide an overview about the project, with special attention given to the two 14.5 GHz electron cyclotron resonance (ECR...

متن کاملOperational Performance of the Lbl 88-inch Cyclotron
The 88-Inch Cyclotron began regular operation with the ECR (Electron Cyclotron Resonance) source in January 1985. Since then about 80% of the cyclotron operating schedule has been with the ECR source. The light-ion filament source is used only for runs two or more shifts in length using proton, deuteron, 3He, or alpha beams. Occasionally the polarized ion source is used. The heavy-ion PIG sourc...
