Construction of the concrete shield cave for the Project X Injector Experiment recently began in the Cryomodule Test Facility building. PXIE is an R&D test accelerator that will replicate the front-end portion of Project X. It will be located at the CMTF building, inside a 150-foot-long concrete shielding cave. The first shield blocks arrived in November and were set in place to form the entry labyrinth of the test cave. Delivery of the blocks will continue over the next couple of months, with the goal of having the first half of the cave built by February 2013 to coincide with the installation of the PXIE ion source.
