I review some recent theoretical issues relevant to the physics of hadron-hadron collisions. I discuss processes where either energy or luminosity is the most important feature and emphasize the need for experiments at luminosities of 10{sup 33}cm{sup -2}sec{sup 1} if the full range of physics options is to be thoroughly explored. 22 refs., 10 figs.

An overview of the continuum regularization program is given. The program is traced from its roots in stochastic quantization, with emphasis on the examples of regularized gauge theory, the regularized general nonlinear sigma model and regularized quantum gravity. In its coordinate-invariant form, the regularization is seen as entirely geometric: only the supermetric on field deformations is regularized, and the prescription provides universal nonperturbative invariant continuum regularization across all quantum field theory. 54 refs.

The storage ring quadrupoles, sextupoles, and correction magnets will be mounted on a common girder approximately 4.0 m long. The rigid girder, in turn, is mounted on three five-ton jacks, each of which is mounted on a pedestal that is grouted and bolted to the floor. For this preliminary analysis, we will assume that the girder has a weight per unit length of 100 lb/ft and a bending stiffness that is significantly greater than the vertical stiffness provided by the pedestal (jack-screw) supports. This allows us to approximate the magnet/support system as a rigid beam (girder) on spring supports (jack-screws) carrying distributed masses (magnets). These approximations permit us to study the rigid body translational and rotational (rocking) modes of the system. It should be noted that the preliminary design has two jack-screw supports at the left end and one at the right end. It should be noted that the magnet/support system studied is only a conceptual design. In actuality, there are five different magnet/support configurations comprising each of the 40 sectors of the storage ring. Also, it is expected that the details of the final design, in particular with respect to the positioning of the pedestal supports, will somewhat different. …

A wire grid beam splitter for use in high-power microwave diagnostics is discussed. The principle application considered here is the Microwave Tokamak Experiment (140 GHz ECH using 35 ns FEL pulses of about 3 GW peak power, single pulse, with future upgrade to 250 GHz, 8 GW, 50 ns, and 5 kHz repetition rate). The theory of wire grids of infinite extent and excited by a uniform plane wave is extended to consider grids of finite extent and excited by field having a Gaussian distribution. Design criteria based on the numerical simulations for the grid to be used in MTX are included along with other appropriate engineering recommendations. 8 refs., 27 figs., 2 tabs.

Within the conventional framework of a spontaneously broken gauge theory, general principles establish that the electroweak symmetry is broken by a new force that may be weak with associated new quanta below 1 TeV or strong with quanta above 1 TeV. The SSC parameters, ..sqrt..s = 40 TeV and L = 10/sup 33/ cm/sup /minus/2/s/sup /minus/1/, define a minimal facility with assured capability to observe the signals of symmetry breaking by a strong force above 1 TeV. Foreseeable luminosity upgrades would not be able to compensate a much lower collider energy for these physics signals. If the strong WW scattering signal were seen at the SSC in the 1990's it would provide a clear imperative for a collider with the physics reach of the ELOISATRON to begin detailed studies of the new force and quanta early in the next century. 35 refs., 7 figs., 4 tabs.

Increased resolution of NMR spectrometry will require the use of very high field Nb/sub 3/Sn superconducting magnets. Here we report the results of our investigation into mechanical and temperature effects on internal-Sn superconductors similar to those proposed for use in a 900 MHz, 21 T NMR magnet system. Thermal precompression was found to be about 0.225%, and the irreversible strain was about 0.8%. Fatigue degradation was not observed at cyclic intrinsic strains below 0.575%. Additions of reinforcing steel in cable conductors was found to reduce the critical current by as much as 50% compared to similar, unreinforced cables. Reduction of the testing temperature to 2.3 K did not increase the critical current in steel-reinforced cables to a level significantly above that of unreinforced samples. 4 refs., 3 figs., 1 tab.

We have measured the relative yield of several low-lying excited states of neutral hydrogen atoms produced by the passage of 226-MeV and 581-MeV H/sup /minus// ions through thin carbon foils and a tilted formvar foil. The relative yields of H/sup /minus///sub /asterisk//(n = 2,3, 4) were measured for 17 different carbon foils ranging in thickness from 662 /angstrom/ to 5386 /angstrom/ at 581 MeV. The relative yield of H/sup 0//sup /asterisk//(n = 2) was also measured for these carbon foils at 226 MeV. These data exhibit a significant deviation from a simple yield curve indicating that a more complex mechanism than has previously been thought is responsible for producing the excited states. The relative yields of H/sup 0//sup /asterisk//(n = 2,3) were measured for a tilting formvar foil at 226 MeV; unexplained dips appear at incidence angles of /theta/ /approx/ 12/degree/ and /theta/ /approx/ 15/degree/ in the yield of n=2 and n=3 states, respectively. 19 refs., 7 figs., 1 tab.

The success of ITER relies on aggressive design of the superconducting magnet systems. This design emphasized high radiation-damage tolerance, acceptance of high nuclear heat loads, and high operational stresses in the Toroidal Field (TF) magnets. The design of the Central Solenoid (CS) magnets, although they will be well shielded from the plasma, is equally aggressive due to the need for very high magnetic fields (14 T) and long term operation at high cyclic stresses. Success of these magnet designs depends, in part, on sound selection and fabrication of materials for structural, superconducting, and insulating components. Here we review the design of ITER and the selection of structural materials for some of the systems that will operate at cryogenic temperatures. In addition we will introduce some of the data that the materials selection is based on and suggest opportunities for future research in support of ITER. 10 refs., 1 fig., 4 tabs.

A new model was developed for analyzing solvent extraction processes carried out in columns. Each column is treated as a series of well-defined equilibrium stages where the backmixing (other-phase carryover) between stages can be large. By including all mass transfer effects in the backmixing value, the same number of stages can be used for all extracted components no matter what their distribution coefficients. This greatly simplifies the calculations required when modeling multicomponent solvent extraction processes. Initial testing shows the new model to be better than either the Height of an Equivalent Theoretical Plate (HETP) or the Height of a Transfer Unit (HTU) method.

This Engineering Note documents the design of the stand to be used to transport the CC Cryostat heads into the D-Zero clean room. Due to the width of the clean room access door, the heads will have to be upright to fit through. This head cart will hold the heads upright and wheel them into the clean room on a guided track. Before the wheels are placed on the heat cart, it will be used as a stand to place the heads on for the purpose of test fitting the super insulation. The head cart will not only be structurally sufficient to support the weight of the heads but also stiff enough to allow a maximum deflection of 1/2-inch at the end of the 48-inch cylinder. The heaviest head assembly weighs about 9000 pounds. Following A.I.S.C. specifications and using a 9000 pound design load, the head cart was initially designed and built and later modified in order to meet the deflection requirements. Bending and tension stresses were limited to two thirds the yield strength. Weld and shear stresses are limited to 0.4*Fy. The C7 X 12.25 channels, the L2.5 X 2.5 X 0.25 angles adn the 1/2-inch plate are all …

A detailed description of the background, technology and application for the development of a coal-fired pulse combustor for residential space heating was provided in the first quarterly report for the period October 1986 - December 1986, That material is omitted from this report. In May of 1988, DOE Contract No. DE-AC22-86PC90278 was modified with the addition of two new Tasks - 1.6 and 13 - as a Phase IA to bridge the gap between Phase I and II of the program. The descriptions of these tasks are now included in Section 1.1. Testing activities during this period were minimal with all effort focused upon resolving the issues associated with the extremely low slurry feed rates required for the unit. The use of a constant pressure slurry feed system followed by a low head peristaltic pump was successful for short periods of time providing the required slurry atomization but exceeded pump design specifications leading to rupture of the peristaltic tube. An attempt was made to locate a commercial pump with the required duty; delivering 1 to 2 gallons per hour at up to 100 psi but could not be located. Design modifications for the peristaltic pump were therefore initiated to meet …

The Collider Detector at Fermilab (CDF) is a large, azimuthally symmetric detector designed to study {bar p}p interactions at the Fermilab Tevatron Collider. Results are presented from data taken with a minimum bias trigger at {radical}s = 630 and 1800 GeV during the 1987 run. The topics include the current analysis of dn/d{eta} and some very preliminary results on short range pseudorapidity correlations and Bose-Einstein correlations. 7 refs., 5 figs., 2 tabs.
