First light from the SPEAR Ring at SLAC July 6, 1973
Ingolf Lindau & Piero Pianetta
Pilot project to extract synchrotron radiation from the SPEAR ring at SLAC. In-alcove video camera imaging light emitted from a fluorescent screen just downstream of the Be exit window. No beam steering beyond global steering for colliding beam operation. Our group, including Gerry Fisher, waiting to see if beam would even make it through all the apertures. SUCCESS on first opening of line!!!!!
