Quiet, please

Fermilab’s natural areas sometimes need some quiet time, too. Photo: Steve Krave, TD

Steve Krave, TD, captured these images of “Mobius Strip” (top) and Industrial Building 1 (middle) directly using an old flatbed scanner and an added lens-bellows assembly (bottom). He put the lens assembly together with spare parts and hot glue. The setup is similar to old large-format cameras (but this uses much more duct tape). Photos: Steve Krave, TD

Fermilab in infrared

In these photos, taken with an infrared-modded camera, visible light shows as blue and infrared light shows as white. Photos: Steve Krave, TD

Sean Johnson, TD, used Fermilab’s 3-D printer to make this model of a strand of Nb3Sn wire, which he then spray-painted. Photo: Steve Krave, TD In 2008, Mauricio Lopes, an associate scientist in the Technical Division, started to build a model of a helical solenoid out of cardboard in order to prove a design concept. The process was painstakingly slow: In a week, he and Miao Yu, a mechanical engineer from TD, had finished only four rings. So Lopes thought…

Night lights

This composite of 214 images taken over 18 minutes shows the flashes of fireflies. Each yellow spot is a single firefly flash. The occasional dashed line is a firefly that was in motion when the photo was taken. Photo: Steve Krave, TD

An egret snuck up behind two turtles sitting on a log in a lake by Wilson Hall last week. A few seconds after this photo was taken, the egret pushed the turtles into the water.
