, 22:55, 13 January 2014→The "[Collimator Cave]"
On January 10th, Sascha Somov took me to the accelerator site for a tour of the Hall D facility. Below are some pictures I took during the tour. Note that the pictures follow direction of the photon beamline; each successive picture is downstream from the previous picture.
