Savannah River Site Annual Meteorology Report 2003

Description: Summaries of meteorological observations collected at the Savannah River Site (SRS) in 2003 reveal a year that was unusually cool and wet. The annual rainfall of 61.2 inches was the third highest of all the years in a period of record that began in 1952. Higher amounts were recorded only in 1964 (73.5 in) and 1971 (68.2 in). Rainfall of 0.01 inch or more occurred on 119 days during the year. Furthermore, the annual average temperature of 62.2 degrees Fahrenheit was the coldest of any year in an available record that dates to 1964. Cool and wet conditions were most pronounced in the spring and summer months. Unusually cold weather also occurred in January and December. The coldest temperature for the year was 12.5 degrees Fahrenheit (Jan 24) and the warmest temperature was 92.4 degrees Fahrenheit (Aug 27). There were no significant occurrences of severe weather (ice/snow, tornado, sustained high wind) during the year. The heavy rain that occurred on April 7 (3.5 inches) was due to an active stationary front over the area and strong southwesterly wind aloft. The remnants of Tropical Storm Bill produced 2.36 inches of rain on July 1. Hurricane Isabelle, which struck the North Carolina coast mid September, did not have a significant affect on the SRS. A thunderstorm on May 3 produced a surface (4-meter) wind gust of 41.7 miles per hour.

Access control system for ISABELLE

Description: An access system based on the one now in operation at the CERN ISR is recommended. Access doors would presumably be located at the entrances to the utility tunnels connecting the support buildings with the ring. Persons requesting access would insert an identity card into a scanner to activate the system. The request would be autologged, the keybank adjacent to the door would be unlocked and ISABELLE operations would be notified. The operator would then select the door, activating a TV-audio link. The person requesting entry would draw a key from the bank, show it and his film badge to the operator who would enable the door release.

Notes on luminosity variation at ISABELLE

Description: In the present ISABELLE design, the luminosity at each insertion will be the same, unless special efforts are taken to get a low-..beta.. insertion or reduced crossing angle. These can only change the luminosity by factors of 2 to 4 from insertion to insertion. An estimation of the range of desired luminosities is given.

Beam dumping at ISABELLE

Description: Safely ejecting the approx. 40 MJ stored energy per beam at ISABELLE is clearly a major problem, both for experimental apparatus and for superconducting magnets. Intensive study of this problem is just beginning. A brief review of the current status is presented.

Two superconducting storage rings: ISABELLE

Description: The general features of the design and the status of the ISABELLE storage ring project at the present time are reported. It brings up to date the results reported at the National Particle Accelerator Conference in March 1977. The most significant change since that time has been an upgrading of the energy of the overall facility, and acceptance of the project by the Department of Energy.

Open areas and open access

Description: One objective of the two open areas in the present ISABELLE design is to provide flexibility with respect to the size and shape of experimental equipment that would eventually be installed there. No permanent building would be installed initially. A second objective of the design of open areas is to keep initial costs as low as practicable. Another objective is open access. This note explores this idea and some design concepts based on it. It would permit inserting large pieces of experimental equipment quickly and removing them with equal ease and speed. Entire experiments would be moved in a single piece (or a few) by building them on movable platforms with capacities of up to about 1000 tons per platform. Most experiments could be built on a single platform or on a few. The shielding must also be moved. It must also be organized into a small number of large units. A scheme using large tanks filled with water is described. It is important to make the equipment on a given platform as complete and self-contained as possible, with a minimum of interconnections for power, coolant, controls, data transmission, etc. 5 figures.

ISABELLE ring structure and performance

Description: A summary of the ISABELLE Ring Structure is presented. A phased approach to ISA operation is detailed. The initial performance potential indicates that p-p collisions at a wide range of energies and unequal energies in the two beams will be possible. The quasi 8-fold periodicity could be broken to allow a hi-luminosity set-up, which could be achieved by small changes in the insertion quadrupole strengths. A discussion is given of future ISA phases requiring the alteration of the physical layout of the insertions for various special experimental conditions. (auth)

Large equipment and facilities

Description: Component and design criteria are reviewed for a general purpose modular multiparticle spectrometer system. The study of hadronic interactions is emphasized, although the solenoidal magnet vertex detector system can be used for W bosons and other weak interaction processes. A general purpose spectrometer seems compatible with the requirements of the ISABELLE straight sections. (auth)

Description: Superconducting accelerator bending magnets in the 4 to 5 tesla field range have been, or are being, developed for the LBL ESCAR, FNAL Doubler, and BNL ISABELLE projects and can be considered as state-of-the-art. We are now engaged in a program to develop accelerator dipoles with significantly enhanced performance, into the 8-tesla range. Analytical design studies, based on idealized configurations, have been done to trace the dependence of stresses within the coil and overall magnet size on the magnet aperture, coil current density, central magnetic field, structural ring stress, and magnetic induction in the iron flux-return yoke. Our development program includes: (1) Development and measurement at 4.2 K, of coil structures consistent with the requirements of the analytical design studies; (2) Superfluid helium II at 1.8 K and at atmospheric pressure, large magnets as well as conductors will be tested; (3) Development and evaluation of aluminum stabilization and various A-15 superconductors; and (4) Tests of various model dipoles with instrumentation to measure mechanical motion.
