Description

This is the first of a series of monthly reports summarizing the status of the work of the National Accelerator Laboratory. This first report will cover developments since the publication of the Design Report in January. Authorization hearings were held before the Joint Committee on Atomic Energy on February 21, 1968. Dr. Wilson described the plans and designs of the Laboratory. The present plan of the Laboratory is that the Village of Weston will be utilized for office, laboratory, and shop space during construction. The Laboratory business office is already occupying several houses. The linac section is occupying three houses ... continued below

Description

This is the first of a series of monthly reports summarizing the status of the work of the National Accelerator Laboratory. This first report will cover developments since the publication of the Design Report in January. Authorization hearings were held before the Joint Committee on Atomic Energy on February 21, 1968. Dr. Wilson described the plans and designs of the Laboratory. The present plan of the Laboratory is that the Village of Weston will be utilized for office, laboratory, and shop space during construction. The Laboratory business office is already occupying several houses. The linac section is occupying three houses for offices and construction of an 8,000 sq ft laboratory building for linac work is almost complete. Another house is being used and a 4,500 sq ft inflatable building is being constructed for model-magnet and vacuum testing. Other temporary buildings will be constructed for use by other sections. We plan to move into the village as rapidly as is feasible and it is planned that the entire technical staff will be located there by October. The Laboratory staff totals 132 people as of April 1. Of these, 47 are physicists and engineers. Design effort has been somewhat concentrated on architecture in order to push toward decisions needed for next year's construction. As a result of 'Architecture Month', beginning February 19, we have fixed the positions and levels of the main ring, the booster, the linac, and the EPB on the site. We have also determined the approximate position and junctions within the 'foot print' of the high-rise building. A particularly dramatic concept of the building has been suggested by the architects--a building of triangular cross-section that leans and is partly supported by an external core that intersects the building near the top. This building will be given further detailed study until April 15 in order to clarify the problems that will arise for a specific building. We will then make a choice as to whether we should develop an entirely new design concept. In addition, the positions of the accelerator buildings on the site have been fixed and are being suitably memorialized (on paper) by DUSAF. A site coordinate system has been adopted. It is described in technical specification TS-l. The theory section is working with the component sections in design of the lattices and in digital computation of magnetic fields. Space-charge effects at transition energy and at full energy are being studied. It is of interest that neutralized space-charge defocusing is rather large. In addition, the negative-mass longitudinal space-charge effect will also affect debunching for extraction and targeting. The DCT-2000 remote-terminal link to the NYU CDC-6600 is now in operation. Efforts are being made to translate programs for the IBM-360 at ANL. A data link will be installed later.
