Key Points

  • This project aims to address the design and production challenges of the KoBRA buncher components using additive manufacturing techniques.
  • Designed and produced four water-cooled stems with drift tubes using 3D printing technology
  • Focused on a cylindrical cavity measuring 540 mm in length and 614 mm in diameter
  • Analyzed RF power operation at levels up to 24 kW.
  • Successfully designed and produced the drift tubes utilizing additive manufacturing techniques
  • Achieved efficient cooling design.
  • Validated the RF operational capability at the targeted power levels.

Abstract

Abstract One key challenge in this project is the design and production of four water-cooled stems with drift tubes for a buncher running at CW operation with RF power levels up to 24 kW. The cylindrical cavity has only a length of 540 mm and a diameter of 614 mm. This paper will discuss the approach of technical design and the production of the drift tubes performed as 3D printing.
