The 28 high school students completed the requirements of the spring session of Saturday Morning Physics. Fermilab Director Nigel Lockyer handed out the certificates and posed for each of these pictures.

I have lots of pictures of my favorite tree, but few with anything other than the tree. Traveling on my own, I used to take selfies before they were even a thing. I also enjoyed black and white infrared when I used to shoot film. It's still possible with digital and only slightly more involved, so this nice sunny Saturday afternoon seemed like the perfect opportunity to do a little of both.

Nigel Lockyer and Elliott McCrory attempt to answer questions from the parents of the Saturday Morning Physics students.

This mourning dove built the third nest in this spot at BEG this year. First it was a chickadee who realized there was not enough support for her nest, then a swallow who presumably got chased away by this successful mourning dove.

Pictured is half of the floor of the warm vessel being lowered to its final location. The steel structure has a footprint of about 85 feet by 25 feet and weighs about 35,000 pounds. Two cranes are simultaneously lowering the structure into place. A group made up of Fermilab and CERN personnel is assembling the warm vessel at the SBN Far Detector Building.

Cinco de Mayo at Kuhn Barn: music, dancing, food, a piñata. Local middle school students also offered special performances to celebrate.

When the first CDF central tracking chamber, the COT, was replaced for Tevatron Run II, we did some work on it so people could see the wires inside it. It is quite a beautiful object. and we were thinking of putting it in the high-rise building, Wilson Hall. This frame is the size of the COT and was designed and built at the Proton Assembly Building to see how the COT would appear in the high-rise. I guess it was decided that it did not fit well.

Nap time for the youngsters

This is a two-piece photo. The top is a 20-inch, approximately 50-pound (if not more) lead-glass block that made up the E-760 electromagnetic calorimeter. The glass has a high lead content and is exceptionally transparent to allow the Cerenkov light produced by fast-moving electrons to reach the photomultiplier at the end, says Stephen Pordes. He also states that the shape is quite unusual. The 1,280 blocks together made up a hollow cylinder. The bottom of the photo is a refection when looking through the rectangular glass. Cool, huh!

Nice to see many of these at Fermilab.
