List of changes since the 2006 HallD Tagging Spectrometer and Photon Beamline Review

In January 2006 the lab held an external review of the Hall D Tagging Spectrometer and Beam Line. The list below represents an attempt to collect in one place all of the changes to the tagger and photon beam line that have taken place since then, up until the PAC report in summer 2010.

1. electron beam dump -- in 2006 the electron beam dump was located in an out-building that was connected to the tagger hall by a buried beam pipe. The present civil design now has the electron beam dump located in the tagger hall, which has been extended in the south-east direction to accommodate it.
