Assembly of the TPC began at Fermilab during the summer of 2012. Everyone is pitching in from summer students to scientists. Check back regularly for updated photos.
Moving a dewar
One of two dewars being moved to LArTF. One will be used for liquid nitrogen and the other will be an argon buffer tank.

LArTF Lowest Level

Platform at LArTF. The cryostat will sit below this and computing racks will be here. The platform is removable for the cryostat insertion. (Photo from Fermilab VMS)
LArTF Platform Looking Up
Looking up from the LArTF platform one can see part of the roof that will be removed for the cryostat insertion (Photo from Fermilab VMS)
Photomultiplier Tube Test

Testing the Wire Boards
A leakage current test for the capacitors ws performed on each of the boards before they were installed.
Part of the Wire Hanging Team
Wire team A poses for a picture. Over 10 people participated in the installation of the TPC wires.
A mesh grid is being considered for shielding outside of the TPC. Here, a wire is strung through the mesh to test assembly.
Pipes and Plane
The pipe of the field cage are being put in place here. The cathode plane is in the background.
can be seen in position. The dark green x's are made of unistrut and are there for bracing (just temporary).
The inside of the pipes were swabbed with wipes after soaking and having the outside cleaned.
The pipes for the field cage were soaked in a Simple Green solution to help remove grease.
All of the field cage pipes had holes drilled to allow liquid argon to flow. The holes had to be deburred.
