This article discusses the abrupt decommissioning of the Princeton-Pennsylvania Accelerator (PPA). The decision to close the PPA came abruptly, just 7 years after its operations began in 1962. The Atomic Energy Commission notified PPA in January 1970, after assuring a $3.5 million budget for the remainder of the fiscal year in November 1969, that their operations would be terminated. The Atomic Energy Commission cut off funding on July 1 1970, just before the opening of the brand new $250 million National Accelerator Laboratory in Batavia, IL. At its peak, the PPA employed 356. Annually, it cost $5 million to operate.
