In this paper, the authors applied Geant4 with the Seitz hot spike model, which has been used for a superheated liquid bubble chamber, to simulate the threshold energy of neutron recoil energy for a snowball chamber. By successfullyreproducing their earlier data, the energy threshold of ~0.2-1.2 keV is obtained.
Although snowball chamber is not a new technique, it is still relatively new for searching for probing the dark matter candidate with O(1) GeV in mass. Since this study is an extension of their work published in [19], the results obtained in this work can be a valuable reference in the literature. The paper is organized well, and the purpose of the study is clear. However, the first photograph in Figure 1 does not look very useful for understanding the experiment setup. The authors may need to use another photograph instead or remove it. Overall, I recommend publishing the paper in Universe
