In the original publication [1], there was a mistake in Figure 5 and the corresponding caption. The figure and the caption did not accurately represent the insulation configuration. The correct Figure 5 and caption appear below.
Figure 5.
Picture of MLI with spherical particles.
In the original publication [1], the particulate material used in our experiments was incorrectly referred to as “hollow glass microspheres (HGMs)”. This is inaccurate, as spherical particles (SP) were actually used as spacers. Therefore, in those parts of the article that describe the particulate material used in the present work (throughout the main text, e.g., in the Abstract, the experimental description in Section 3 “Experimental System for Liquid Helium Insulation Characteristics”, and the relevant equations such as Equation (29)), the term “hollow glass microspheres” and the subscript “HGMs” should be replaced by “spherical particles (SP)” and “SP”, respectively, and the sentence immediately above Equation (29) has been corrected from “for hollow glass microspheres” to “for spherical particles (SP)”. A clarifying sentence, “Spherical particles (SP) were used as spacers.”, has been added to the last paragraph of the Introduction, and the previous description of HGMs as spacers in Section 3 has been removed accordingly. By contrast, the occurrences of “hollow glass microspheres” in the literature review part of the Introduction, where we summarize previous studies, correctly describe the materials used in the cited works and therefore remain unchanged and are not subject to this replacement. In addition, the citation [24], which previously appeared in the sentence immediately above Equation (29), has been moved to the sentence immediately following Equation (29), and the abbreviation “SP” has been added to the list of abbreviations as “spherical particles”.
The authors state that the scientific conclusions are unaffected. These corrections were approved by the Academic Editor. The original publication has also been updated.
