The following document gives a baseline list of all beam diagnostic systems in the TJNAF Free Electron Laser. Contact the Diagnostics Review Committee (G. A. Krafft, D. Douglas, K. Jordan, S. Benson, R. Legg, or C. Bohn) to make recomendations for changes. A name and general location is given for each beam diagnostic element. Names in parenthesis (), are tentative (i.e. unofficial as nomeclature is not yet established), and will be updated as more nomenclature decisions are made.
