hed SORhte the Conmission undertake such a step, and we reaffirm this recommendation. We discussed at length the question of whether the machine should be built at a university or at one of the National Laboratories, The conclusion to which we unanimously came is that it should be constructed at a National Laboratory. Despite the enthusiasm of various university groups to build and operate such a facility, we fail to see any really convincing reason for associating an aceelerator of this size with a university campus. We do not feel that it would be a vital element in the instruction of students or in any way an extension of the normal functions of a university department. On the other hand, it is basic to the whole concept of the National Laboratories that they shall supply central research facilities of an advanced nature for the use of cooperating universities and other research institutions in their region. We believe that it should be the policy of the Commission to see that the National Laboratories are equipped with the best and most advanced nuclear research facilities, e.g. large accelerators, that can be built with the existing technology and available funds at any particular tine. To adopt any other course would, indeed, jeopardize the ability of these Laboratories to play the role in our national scientific effort for which they were established, There has been built up at the Brookhaven National Laboratory a very strong momentum in the ultra-high energy accelerator field as a result of their success with the cosmotron and in the further development of the "strong focussing" principle, We feel it important to utilize this momentum, which is a very valuable current asset of the Commission, In view of these considerations, it is our recommendation that this accelerator be constructed at the Brookhaven National Laboratory, We also recommend that the Commission issue a clear statement of its policy in such matters, sirce this would do much toward insuring that the interests and enthusiasms which exist are directed along the most constructive and efficient lines of effort. 3. The Conmittee was most favorably impressed with the progress which has been made since our last study of Project Gabriel, now labelled Project Sunshine. We feel that we are now on solid ground for further exploration of this important question. We recommend that the Commission proceed expeditiously with the immediate program of sample collection and analysis. From the presentation we had from the staff of Project Sunshine and from Dr. Libby we obtained a strong impression that this information may become vital tests, and, in the event of war, may be of the greatest importance in determining tactics and strategy, All concerned with the re-orientation of this Project during this last summer are to be congratulated on a very satisfactory performance. com ts
