There were several errors in figure 11 of the original article. While the first panel, showing the bubble distribution for the low fluence of 1.1 × 1024 He m−2, is correct, the second panel was mistakenly duplicated from the first. Additionally, the third panel should display the distribution data for the higher fluence of 5.0 × 1024 He m−2, and the data for the highest fluence of 5.0 × 1025 He m−2 was completely omitted. These errors have been addressed in the corrected figure 11 provided in this corrigendum.
