Objectives
The objective is to develop a new travelling wave tube with the output power of 500W. The output power is doubled compared to today’s products. Key issues are
1) higher dissipation power, but still below 4W/cm2 which is enables the usage of today’s state of the art heat pipes.
2) enough margin for multipaction in the output section.
Another objective is to keep as much heritage from today’s travelling wave tubes respecting the specified typical space requirements based on twice of the rf power of today.
Challenges
- Achieve the output power
- handling the dissipation power
- achieve a good margin for multipaction in the rf output
- achieve a good thermal contact
- keeping the standard requirements (electrical, mechanical and thermal)
