Particle-In-Cell Simulations of High Efficiency 12-Vanes 2.45 GHz Continuous Wave Magnetron

Round 1

Reviewer 1 Report

This paper presented a design of a high-efficient CW magnetron working at 2.45 GHz. The performance of the device was shown through simulations. The results are interesting, and the paper can be accepted for publication after addressing the following questions and comments.

1. There are a couple of typos or errors across the paper. For instance, in Line 160, the "is" before "represents" should be deleted. In Line 233, "3950GS" should be "3950Gs". The authors should fix them.

2. In the Simulation part, the authors observed a fluctuating trend of the work efficiency with the increasing anode voltage. The authors should provide some reasonable explanation to help the readers understand this behavior. Why is the trend not a linear one?

3. Since only simulation results have been provided, the authors should comment on the potential challenges to realize this device in the real world.

Reviewer 2 Report

I think the paper is structured well and pose interest to readers. It would be great if we can have more clear, precise, and brief paragraph for motivation, novelty, and methodology for the research maybe in concept section or before that.

 

Additional comments to question guide from reviewer

1. What is the main question addressed by the research?

- Investigation about a CW magnetron which is novel in design with a high efficiency. They have also worked to improve the mode separation.

2. Do you consider the topic original or relevant in the field? Does it address a specific gap in the field?

- I think topic is relevant in vacuum devices field and since the design is improving the efficiency then surely it is relevant.

3. What does it add to the subject area compared with other published material

- I think it differentiates it to other articles is by improved efficiency using 12 vanes. I also think chosen frequency is 2.4 GHz which makes it more appealing to readers.

4. What specific improvements should the authors consider regarding the methodology? What further controls should be considered?

- I think the anode voltage and period of stable operation.

5. Are the conclusions consistent with the evidence and arguments presented and do they address the main question posed?

- Yes, it does.

6. Are the references appropriate?

- Yes

7. Please include any additional comments on the tables and figures.

- I think it is OK. The main aim of the paper is to demonstrate the efficiency improvement.

Reviewer 3 Report

1-In Fig. 6, the vertical axis is for power, but there are negative values. Please check or explain.

2-The paper is well-written and easy to follow.

 

Additional comments to question guide from reviewer

1. What is the main question addressed by the research? - The paper develops a high-efficiency 12-vanes CW magnetron and anode resonance system aiming to improve mode separation and expand the working space of π-mode.   2. Do you consider the topic original or relevant in the field? Does it address a specific gap in the field? - There is enough contribution to the state of the art in the field.   3. What does it add to the subject area compared with other published material? - The increase in the efficiency as the applied voltage was increased.
4. What specific improvements should the authors consider regarding the methodology? What further controls should be considered? - The dimensions were optimized to obtain better performance.
5. Are the conclusions consistent with the evidence and arguments presented and do they address the main question posed? - Yes
6. Are the references appropriate? - Yes
7. Please include any additional comments on the tables and figures. - The figures should be centered. For better clarity, the font of the axes should be larger.
