Things dug in Durham, North Carolina. Includes 1912 German 2-pfennig coin. Wonder who dropped it. Immigrant? Veteran?
Ta-daaa! This is the shiny new pixel detector, assembled in a clean room at ground level. It has since been installed in the ATLAS experiment. It is meant to give another, greater level of particle position detail, as the energies of the particles and collision rates increase during the next run of the LHC. This is the very innermost level in the experiment, directly next to the particle beam tube.
The "poison" sign and all the plastic protection around the tube are due to the use of beryllium in its construction. Apparently beryllium can be extremely thin and still maintain strength/a vacuum; this thinness is important in order to minimize the amount of material between the collision zone and the particle detectors (the more material, the more likely the particles are to interact with that material and be altered in some way). Beryllium also happens to be hazardous to one's health.

This is a closeup of the photodiode detector of the UV LED modulator.
The photodiode is the SFH203P with a 1Kohm resistor over it.
FERMILAB PHYSICIST INSPECTS THE PROPER POSITIONING OF ONE OF CDF'S TWO END CAPS INSIDE THE DETECTOR.
FERMI'S TWO DETECTORS, THE COLLIDER DETECTOR FACILITY (CDF) AND D-ZERO ARE ABOUT FOUR STORIES HIGH, WEIGHING ABOUT 5000 TONS EACH. THE PARTICLE COLLISIONS OCCUR RIGHT IN THE MIDDLE OF THE DETECTORS, WHICH ARE CRAMMED WITH ELECTRONIC INSTRUMENTATION.

Just after the first sanding of the durabond and drywall mud fill. I've added the final mud skim coat and it just needs a light sanding once dry.

More fun stuff from work. These are most of the internals of the detector rendered in "Cryogenic Detector Outside". The detector itself is pretty much buried under other crud.
The big orange cone is the bottom half of the cold finger assembly. (It will be made of OFHC copper, hence the orange color.) The upper half is bolted to the cryogenic cooler itself. In order to disassemble the camera, the cooler assembly is unbolted and removed. The only connection to the cooler assembly is this two piece cone system. This helps the cooler center on the cold finger assembly, and assures good thermal contact. The mating halves of the cone assembly are manufactured at the same time, and are then lapped together to ensure good contact.
Most of the thermal isolation is visible. The three vertical tabs are G10 phenolic, which provide the thermal isolation between the cold bits of the camera and the warm bits. The arrangement is also quite stiff, so things shouldn't move around much.
The two horizontal tabs (which are not quite the same shape, unfortunately) don't really offer thermal isolation. They're big springs whose job is to hold the cold finger assembly against the back of the detector.
