file:jbhd3.jpg|This is where the photon beam first enters Hall D. The tagger hall is 17 meters upstream.
file:jbhd4.jpg|This is the apparatus that will hold the active collimator.
file:jbhd5.jpg|A pic of me next to the future home of the active collimator. Photo credit to Sascha.
file:jbhd6.jpg| You can see the hole through which the photon beam will travel in this pic. The blue housing is a magnet to deter the electrons and positrons formed by pair production.
file:jbhd7.jpg| The backside of the magnet in the previous pic.
file:jbhd8(2).jpg|The second, "primary" collimator.
file:jbhd8.jpg| A downstream shot of the collimator cave. That's Sascha on the right.
file:jbhd10.jpg| A piece of equipment to eliminate the secondary photon "halo" around the photon beam.
file:jbhd11.jpg| A second magnet.
file:jbhd12.jpg| This is where the collimated beam will exit the second magnet.
file:jbhd13.jpg| An upstream view of the "Collimator Cave."
file:jbhd14.jpg| The collimated beam will travel through this opening to the main room of Hall D, where the Barrel Calorimeter (BCAL) and Forward Calorimeter (FCAL) are located.
