Oak Ridge 25URC tandem accelerator 1994 SNEAP lab report

PDF Version Also Available for Download.

Description

The 25URC tandem accelerator is still in shut-down mode until the facility is reconfigured to produce radioactive ion beams (RIBs). Again, the authors have operated approximately 200 hours for ion implantation studies in support of RIB development. Operation of the accelerator has been generally very reliable with most problems being associated with power supplies and components located outside the accelerator. The major operational problem this year was the development of internal shorts in the coils of the energy-analyzing magnet which caused beam instability. The major development activity for the tandem accelerator was the replacement of the corona-point voltage-grading system with ... continued below

Description

The 25URC tandem accelerator is still in shut-down mode until the facility is reconfigured to produce radioactive ion beams (RIBs). Again, the authors have operated approximately 200 hours for ion implantation studies in support of RIB development. Operation of the accelerator has been generally very reliable with most problems being associated with power supplies and components located outside the accelerator. The major operational problem this year was the development of internal shorts in the coils of the energy-analyzing magnet which caused beam instability. The major development activity for the tandem accelerator was the replacement of the corona-point voltage-grading system with resistors. Several milestones for the RIB project have been met since SNEAP 1993. The high-voltage platforms have been built and tested at the required 300 kV. Most equipment has been installed on the platforms so that the first beam can be developed using the Mark I target-ion source. This ion source was characterized on the ion source test facility before moving it to the platform. The second-stage mass-separator magnets have been specified and the contract has been awarded to Sigma Phi. The final optics design for the beam line from the second-stage separator to the tandem accelerator is being completed and equipment and controls are being procured.
