On Feb. 17, 2021, in Lab B at SiDet, Fermilab scientist Juan Estrada and technical specialist Andrew Lathrop stand on either side of the outer shell for the prototype vessel that they have developed for the operation of charge-coupled devices in a liquid nitrogen bath.

Greg Derylo took this photo using a pinhole camera fashioned from an aluminum can and a sheet of photo paper. Mounted on a fence outside Lab B facing the Fermilab bubble chamber, the camera took a 13-week-long exposure that shows the sun’s path every clear day over that period.
