| 英文摘要 | The AGOR-facility has an on-going upgrade program aiming at intensities beyond 1012 pps for heavy ion beams up to Pb. The main elements of the program are: further development of the ECR-source, improvement of the transmission into and through the cyclotron, and protection of equipment against excessive beam loss. Further improvement of the ECR ion source is facilitated by the installation of a second source. Redesign of the Low Energy Beam-line, to compensate for aberrations, is in progress; simulations predict a significant increase in transmission. A new, cooled, electrostatic extractor is being commissioned and the beam loss control system has been completed. The main remaining issue is vacuum degradation induced by beam loss caused by charge exchange on the residual gas. Tracking calculations of the distribution of the beam losses over the vacuum chamber to determine the optimum location of scrapers are underway. A gold coating was recently applied to relevant parts of the vacuum chamber aiming at reduction of beam loss induced desorption. |
