Microwave Diagnostic Systems and Techniques for Use in Controlled Fusion Research

Description: Abstract: "Microwaves have been used for several years at Lawrence Radiation Laboratory to study conditions in the magnetically contained plasmas of controlled fusion research. There are two basic microwave techniques. One gives information on electron density and distribution in the plasma, the other provides data on electron temperature. This paper briefly summarizes the established techniques, discusses engineering requirements and limitations, and describes some further applications of micr… more

Discussion on Optimization of Large Oil-Pumped Ultra-High Vacuum Systems

Description: Abstract: "Discussion is directed toward eventual optimization of the largest diffusion-pump systems. Less than 100 diffusion pump fluid molecules per cm 2/sec are possible to detect using an accumulation method. Optimization discussed demands highest possible system speed compatible with the above contamination rate. Bakeable oil diffusion pump systems, with equal orifice valve-tap units, without conventional baffling, permit theoretical through-put speeds up to 0.3 of the system orifice. The … more

Scintillation Counter [gamma]-Spectra Unfolding Code for the IBM-650 Computer

Description: Abstract. An IBM-650 computer code for the detailed unfolding of [gamma]-ray spectra obtained from NaI scintillation counters has been developed. The procedure is set up to remove analyzer scale dependence and to largely remove energy dependences. Computer time is about 1 minute per [gamma]-ray.

Non-military Uses of Nuclear Explosions

Description: Introduction. With the development of fission and subsequently of thermonuclear explosives, a very large source of cheap energy has become available. The problem of using this energy for peaceful purposes safely and economically presents itself as one of the most interesting and important of our time. In explosions the energy is released very suddenly. Conversion of this sudden release of energy at extremely high temperature and pressure into the form of useful work, either mechanical or chemic… more

Seismic Decoupling for Explosions in Spherical Cavities

Description: Abstract. A series of paired explosions in a salt mine near Winnfield, Louisiana, has been conducted to test a theory by Dr. A. L. Latter concerning seismic decoupling by underground cavities. The theory predicted a decoupling of about 100. Free-field and surface measurements from an explosion in either a 6-ft- or a 15-ft-radius spherical cavity were compared with similar measurements from a completely tamped explosion. Shot sixes were from a 10 lb up to a few tons. Surface measurements were ma… more

A New Liquid Explosive, NTN

Description: Abstract. The preparation and properties of a new explosive, liquid over the range -65 degrees F to +165 degrees F, are presented. This explosive, called NTN, is a 5/1/1 mole ration of nitromethane, tetranitromethane, 1 -nitropropane. The sensitivity and stability of NTN meet military requirements.

Transient Thermal Stress in Tubular Reactor Elements

Description: In this paper, a theoretical solution is developed for the transient thermal stress distribution in a reactor fuel tube of circular cross sections with spatially uniform internal power generation and forced convective heat transfer at the inner surface of the tube. Solution of the equation of heat conduction is done my means of a Laplace transform with subsequent application of the inversion integral to arrive at a final expression for the transient temperature distribution. The solution is of … more

Tory II-A Instrumentation System : Brief Description

Description: Abstract. The Tory II-A reactor is a small, air cooled, high power-density reactor which is to operate at quite high temperatures. Design of the reactor is essentially complete. First operation is scheduled for late 1960 at the Nevada Test Site of the Atomic Energy Commission. Since the reactor is unshielded, the control room which houses the recording and indicting equipment is located approximately two miles from the test bunker. Signals from reactor and facility transducers are amplified in … more

Neutron Diffusion Theory Programs and Their Application to Simple Critical Systems

Description: Introduction. The Lawrence Radiation Laboratory of the University of California has developed a series of reactor neutronic programs for an IBM 709 Data Processing System.. This paper presents a brief outline of these codes and includes the results of one- and two-dimensional diffusion calculations used to interpret data from a series of enriched-uranium beryllium-oxide moderated critical measurements. These were performed for the specific purpose of evaluating the computer programs. The time-i… more

Monte Carlo Schemes for Neutron Migration Using Importance Sampling and Splitting

Description: Abstract. Monte Carlo methods using importance sampling and splitting are proposed for estimating the effectiveness of neutron shields. As usual, the aim is to increase the number of particles that go through or around the shield, this increase being compensated by a decrease in the weights of these particles. With suitable modifications, the ideas are applicable to to other Monte Carlo problems. One way of using splitting and Russian roulette is to require that the weight of each particle be a… more

State of Matter at High Pressure

Description: Abstract. The region where exact thermodynamic description of the state of matter at high pressure and high temperature is possible is located. In the remaining region various approximate theories and empirical relations are discussed. These considerations are applied to hydrogen to locate the density and pressure at which the diatomic bond collapses. Also the approximate conditions are determined at which no bound electron states exist.

High Current Pulsed Electron Accelerator

Description: The most important component required for the Astron experimental facility is a high energy, high current, pulsed electron accelerator. A thin cylindrical layer of high energy electrons trapped within an axially symmetric magnetic field is the key feature of the Astron thermonuclear device. The trapping magnetic field is constant in time. Therefore, it is not possible to inject electrons and trap the electrons in this field unless during the injection phase a part of the electron energy is abso… more

On the Establishment of a Temperature Function

Description: Among the thermodynamic variables, which include temperature (T), energy per unit mass (E), volume per unit mass (V), pressure (p), and others any two may be selected as independent, and on this pair will depend, in principle, every other variable, each such relationship constituting an "equation of state". Thus, the common choice of V and T as independent variables implies that E is given by a function E(V,T), p by a function p(V,T), and similarly for the other variables. Occasionally, it is d… more

Standardization in the Design and Construction of Electronic Instrumentation and Control Systems

Description: Abstract. An extensive activity at the University of California Lawrence Radiation Laboratory is the design and construction of elaborate electronic systems for instrumentation and control of test and research facilities. Design and construction of these large scale electronic systems is guided by principles and practices of standardization which reduce system cost and completion time. A summary of these standardization principles and practices is presented.

The LRL Capture-Gamma Coincidence Spectrometer

Description: Abstract. A fast-slow coincidence scintillation spectrometer for gamma-gamma cascade measurements following thermal neutron absorption in nuclei is now in operation at the Livermore 1-megawatt pool-type reactor. Design features of the spectrometer and experimental techniques in its use are discussed with particular emphasis on the application of the recently introduced sum-coincidence method for analysis of capture-gamma double cascades. A new technique for the determination of added neutron bi… more
