3D Proton Bragg Peak Visualization and Spot Shape Measurement with Polymer Gel Dosimeters
Round 1
Reviewer 1 Report
The authors have presented an investigation which employs polymer gel dosimeters to measure the spot size and scanning positions for the Shanghai Advanced Proton Therapy 12 facility (SAPT). The paper is well written and contains backings from experimental results. However, for the manuscript to be qualified to be accepted for publication in the Applied Sciences Journal, I would like to suggest the following corrections:
1. In section 2, a subsection needs to be included for the identification of the materials used
2. Analysis needs to be conducted for the confirmation of the successful preparation of the polymer gel

Reviewer 2 Report
The key is to prove that all these measurements are reproductible. There is a huge interest in proton therapy for such detectors.

Reviewer 3 Report
Overall, it is a well planned and presented article. There are a few points that caught my attention as follows:
1. In figure 4, a, b, c is not shown on the picture, although it is in the description. There is also the same problem in Fig 5, Fig 7, Fig 8 and Fig 9.
2. In discussion, the results are rewritten, but there is little comparison or discussion with the findings in the relevant literature.
Did the authors discuss the study results with the literature? For example, the 13. literature?
Is there any information on literatures related to” Reproductivity of polymer gel dosimeter manufacturing can cause uncertainty to the measured results” sentence for discussion.
The article could be even more robust if the authors contributed a little more literature to the discussion.
The article can be accepted after the necessary corrections are made.

Reviewer 4 Report
In this study, the authors used two polymer gel dosimeters to measure FWHM, scanning positions, and Bragg peak range of the pencil beam spot. Compared to the previous studies, the design concept and materials preparation is not new, and the obtained data are not superior to the former research. Although the measurements in this study were made on the pencil beam, the novelty of this study is far from the standard of Applied Sciences. Furthermore, the article is poorly written particularly the figures.
Significant deficiencies include but are not limited to:
1. There are no letters (such as a and b) on any of the figures that should be there to designate particular parts of the figure.
2. Values are presented without their errors.
3. Figures 5 and 6 have significant issues.
4. Section 3.4: What the authors did, why they did it, and what is depicted in Figure 9 are all unclear. Additionally, the discussion and conclusions make no mention of this section at all.
5. The conclusions are not drawn correctly based on the information provided.
