Background: Disk-load waveguide travelling wave accelerator is wildly used in many areas. However, high cost and low fabrication efficiency of the accelerating tube turn out to be barriers for its widespread application. Purpose: This study aims to develop a new accelerating cavity and accelerating tube processing technology to reduce the cost and production cycle. Methods: A 3D electromagnetic-field simulation software was utilized for the calculation of the RF parameters and the optimization of the accelerating structure. Results: The results showed the concordant RF parameters were between the trap-cut accelerating cavity and disk-load waveguide accelerating cavity, and the former was of advantage in precise tuning. Compared with traditional processing technology, cold extrusion is proved to be a more efficient process in accelerating tube manufacturing. Conclusion: A trap-cut accelerating structure combined with cold extrusion will help promote mass production of accelerating tube.
