Beam was first injected into the AGS May 19, 1960, and was observed on a fluorescent flag after one turn. On May 26, the inflector was pulsed and a spiralling beam obtained. The radiofrequency accelerating system was not completed until July; a trial of the starting oscillator with 5 rf stations, on July 17, accelerated beam for about 2 msec (the duration of the oscillator program). The phase-lock system was switched on and adjusted on July 21 and 22, when occasional beam survival to transition
was observed. Although the scarcely completed rf system had not been adequately tested an attempt to accelerate to full energy was made on July 25. It failed. After a few days of electronic measurements and adjustments, acceleration to 31 BeV was achieved on July 29, 1960. The running-in was satisfyingly straightforward, with no difficulties other than the usual defects of untried apparatus. (Extracted from the introductory part of the paper.).
