Fast reactor analytical shielding progress report for July and August 1973. 189a No. 10318, activity No. HN 04 01 01 1

Description: Analytical shielding work performed for the fast reactor program during the months of July and August included calculations for both the FFTF and the Demo plant, computer code development, analyses of TSF experiments, and a cross- section sensitivity study of a TSF experiment. Most of the FFTF studies were aimed at determining the effect of various design changes on the dose rates at the maintenance deck during reactor operation, in particular, the effects of penetrations through the radial cav… more

Measurement of N* Production in p p ---> p N* between 9-GeV/c and 300-GeV/c

Description: The authors have measured the missing-mass spectrum of p + p {yields} p + MM in the region 1.5 < MM < 7.0 GeV using the acceleration ramp of the NAL machine between 9 and 300 GeV/c and the H{sub 2} jet target. They observe strong N*(1690) and N*(2190) production and are continuing the search for heavier mass resonances.

Diffraction dissociation in 205 GeV/c $pi$$sup -$p two- and four-prong interactions

Description: From meeting of the division of particles and fields; Berkeley, California, USA (13 Aug 1973). Data are presented on diffraction dissociation in pi /sup -/p yields pi /sup -/p and pi /sup -/p yields pi /sup -/ pi /sup - / pi /sup +/p interactions at 205 GeV/c. Mass spectra and cross sections for pion dissociation and nuclear dissociation are presented. (LBS)

Comments on capabilities, limitations, and correctness of Petri nets. Report 26

Description: Petri nets were one of the earliest contributions to the theory of parallel computations and appear to be a natural way to represent the coordination of asynchronous events. Petri nets, however, are not restricted to modelling coordinates in computer systems. Any system where there are loosely connected essentially independent processes that proceed in an asynchronous marner can be modelled using Petri nets and should be useful in modelling business systems and biological systems.

Survey of techniques to reduce/minimize the control part/ROM of a microprogrammed digital computer

Description: A survey was made of most of the important research to date on minimizing the control part of a microprogrammed digital computer. The results appear to be negative, i.e., the Glushkov and Schwartz approaches do not seem feasible in any practical environment. If the requirements of minimal solution are removed so that one would be satisfied with a near minimal solution, the integer programming method can be used since a very good solution is usually obtained after the ftrst iteration.

Experimental investigation of a superconducting niobium X-band deflecting cavity and suggestions for the design of the deflectors for a superconducting rf beam separator at NAL

Description: Design considerations for a deflecting cavity intended for a superconducting rf beam separator at NAL are reviewed. The design parameters given are based on an investigation of a 7-cell niobium test deflector operating at 8.665 GHz. Peak magnetic field of 740 G, corresponding to a peak electric field of 25 MV/m, and an equivalent deflecting field of 6.9 MV/m were obtained. (auth)

Eccentric rf deflecting structure

Description: For superconducting rf separators, assembled by electron beam welding techniques, two types of mode stabilizers are discussed: the elliptical structure, and a new design called the eccentric structure''. For an operating pi /2 or pi mode in the lower pass band, it is shown that the various parameters of the eccentric structure can be adjusted to provide the required frequency spacing between the operating mode and the upper dispersion curve.

Transmission scanning II

Description: From nuclear science symposium; San Francisco, California, USA (14 Nov 1973). Work has been continued on the development of techniques for imaging spatial elemental distributions by means of differential absorption about the K- absorption edge of the particular element Z. A method to correct for spurious effects due to differential absorption in overlying absorber is described. Initial clinical studies of thyroid iodine images on patierts are presented. Application of absorption edge transmissi… more
