Summary
<a href="https://en.wikipedia.org/wiki/Cloud_chamber" class="extiw" title="w:Cloud chamber">Cloud chamber</a> photograph of the first <a href="https://en.wikipedia.org/wiki/positron" class="extiw" title="w:positron">positron</a> ever observed
Original caption: A 63 million volt positron (Hρ = 2.1×105 gauss-cm) passing through a 6 mm lead plate and emerging as a 23 million volt positron (Hρ = 7.5×104 gauss-cm). The length of this latter path is at least ten times greater than the possible length of a proton path of this curvature.
