In the subject contract Stanford was obligated to provide a total of 3000 hours of FEL experimental time a rate of 1000 hours per year. As of 31 December, 1993 a total of 2161 hours of experimental time had been delivered and as of 31 December, 1994, the end date of the contract, a total of 4218 hours had been delivered. A twelve-month moving average of FEL experimental time, as proposed and as delivered, is shown in Fig. 1. The shaded portion of the curve indicates concurrent or parasitic experimental time. The percentage of FEL experimental time allocated to Core User Groups, External User Groups and to System Development during each running period is shown in Fig. 2. The influence of the 16th International FEL Conference, held at Stanford in August, 1994 is evident. In the twelve months preceding the conference, FEL beam time was allocated to those experiments most likely to yield publishable results. Furthermore, a special effort was made to complete our optical diagnostics and control systems and the far- infrared FEL known as FIREFLY. These factors temporarily created a bias away from External User Group research. Despite this, 36.4 1534 hours of the total experimental time through 31 December, 1994 was allocated to External Users. During this same time period 50.8 2134 hours was allocated to Core User Groups and 12.8 541 hours to System Development.
