MOZMH01 | Experience and Lessons with the SNS Superconducting Linac | 26 |
|
||
Experience and lessons with the SNS superconducting linac over the first 5 years of commissioning and operation are reviewed. As the beam power was ramped up to 1 MW, the linac beam loss has been maintained below 1 W/m and residual activation has been held to a safe level. This can be attributed mainly to a robust accelerator design as well as to dedicated beam dynamics studies during this period. In addition to a review of both transverse and longitudinal beam phase-space measurements, we will review several hardware lessons learned with this high-power proton linac − such as nonlinear multipole components of the linac quadrupoles, beam collimators, high-order-mode couplers of the superconducting cavities, and cavity piezo tuners. |

MOZMH02 | World-wide Development of Intense Highly Charged Superconducting ECR Ion Sources | 31 |
|
||
Advancement of nuclear physics and high power heavy ion accelerator is always a driving force for persistent development of highly charged ECR ion source. Increasing demands for more intense and higher charge state heavy ion beams have dramatically promoted development of ECR ion source technology and physics. This talk provides an overview of intense highly charged superconducting ECR ion sources built by the world-wide laboratories in the last years. The key technologies, challenges and main issues related to construction and operation of high performance superconducting ECR ion source are reviewed. The latest results of intense highly charged ion beam production from the superconducting ECR ion sources are presented. Future development and the next generation highly charged ECR ion source are discussed. |
