Schedule and Energy. At the annual Users Meeting on April 10 and 11 announced that, with continuing good luck, it is now possible that we will have an accelerated proton beam by mid-, a year earlier than the originally scheduled date. It also appears possible that a few protons can be accelerated to an energy of 500 BeV not long after the synchrotron is brought into operation.

Construction Progress. a. Booster. The West Gallery of the Booster was occupied by the Laboratory in April. The entire contract is 86% complete

it should be noted that considerable piping and bus -duct installation work has been added to this contt'ad and the contract has therefore been extended. This piping and duct \vork is almost completed and installation uf cable trays and other supply lines is starting. An aerial view of the work is shown in Fig. 1. b. Utility Plant. Erection of the steel framework has been completed. Several major pieces of the heating equipment have been delivered and are -2- NAL-41 0090.01 being installed. Work on excavating the booster cooling pond has begun, as can be seen in Fig. 1. (The pond inadvertently went well ahead of its
