| TUPAN079 | Scheme for Flattening of Ion Density Distribution on a Target | 1556 |
|
||
| A scheme for flattening of the ion density distribution on a target is considered. The aim is to obtain the ion density distribution with deviation from the medium level not more than 5% on the target having rather big dimensions (up to ~60 cm in width and ~30 cm in height). Such kinds of targets are required for some technological purposes. The Xe ion beam extracted from a cyclotron has the following parameters: mass-to-charge ratio is 4.4, the kinetic energy is 4.2 MeV per nucleon, the beam current is 1 and the beam emittance is equal to 40 mm mrad. The ion beam line consists of quadrupoles doublet and oqtupole lens. After passimg through two quadrupoles the ion beam has big horizontal and small vertical dimensions. After that the oqtupole makes the horizontal ion beam density distribution on the target uniform withing the nessary demands. The geometry of the beam line, the quadrupole and oqtupole lens parameters are found during simulation. The simulated final beam density distribution on the target is also given. | ||

|
||
| The screening of the optical elements placed at the horizontal part of the axial injection beam-line of the C400 cyclotron for hadron therapy is performed. An influence of the injection channel shielding elements on magnetic field distribution in the median plane of the C400 cyclotron was studied. The 3D ANSYS model is used for this purpose. | ||
| TUPAN081 | Axial Injection Beam-Line of C400 Cyclotron for Hadron Therapy | 1562 |
|
||
| The axial injection beam-line of the C400 cyclotron for hadron therapy is presented. The influence of the strong magnetic field from the cyclotron on particles dynamics is taking into account during simulation. The effect of the beam space charge neutralization due to residual gas in the beam-line on parameters of the injected beam is evaluated. | ||
| TUPAN110 | On Feasibility Study of 8 MeV H- Cyclotron to Charge the Electron Cooling System for HESR | 1631 |
|
||
| A compact cyclotron to accelerate negative Hydrogen ions up to 8 MeV is considered the optimal solution to the problem of charging the high voltage terminal of the Electron Cooling System for High Energy Storage Ring at GSI (HESR Project, Darmstadt). Physical as well as technical parameters of the accelerator are estimated. Different types of commercially available cyclotrons are compared as a possible source of a 1 mA H- beam for HESR. An original design based on the application of well-established technical solutions for commercial accelerators is proposed. | ||

Funding: Work supported by the Universities Research Assoc., Inc., under contract DE-AC02-76CH03000 with the U. S. Dept. of Energy Presently the Fermilab Booster can accomodate about half the maximum proton beam intensity which the Linac can deliver. One of the limitations is related to large vertical tuneshift produced by space-charge forces at injection energy. In the present report we study the nonlinear beam dynamics in the presence of space charge and magnet imperfections and analyze the possibility of space charge compensation with electron lenses. |
