Construction of the Courant-Snyder invariants for the non-linear equations of motion and criterion for the long-term stability of the beam in a storage ring

Description: The Courant-Snyder invariants become Lyapunov functions when the [beta]-functions admit non-zero lower, and finite upper bounds. The long-term stability of motion then follows. This alternative criterion for the long-term stability of motion can be generalized to the nonlinear case. A single particle subjected to an arbitrary static magnetic field is considered in some detail, as an example.

Low severity upgrading of F-T waxes with solid superacids

Description: In the last quarters a new class of solid superacids, including sulfated zirconium-hafnium oxides and ZrO[sub 2]/SO[sub 4] modified by Mn and Fe, were synthesized and shown to be active for isomerization and hydrocracking of hexadecane (n-C[sub 16]H[sub 34]). The reaction was carried out in a tubing bomb under mild conditions: 2.5 MPa and 433 K. Pt/HfO[sub 2]S0[sub 4] catalyst exhibited a low activity for hydrocracking of n-C[sub 16], but the addition of ZrO[sub 2] to the sulfated hafnium impro… more

Fundamental mechanisms in flue gas conditioning. Quarterly report, July 1992--September 1993

Description: As suggested by our literature review, our data indicate that water adsorption depends on particle morphology and surface chemistry. Our recent laboratory efforts were directed primarily toward the determination of the effects of adsorbed water on the tensile and cohesive strengths of powders, and the conditioning of powders and ashes with SO{sub 3} and organosiloxane. Details of these conditioning methods are discussed under section 3.5.

Development and testing of the Perseus proof-of-concept aircraft. Final report

Description: Many areas of global climate change research could benefit from a flexible, affordable, and near-term platform that could provide in situ measurements in the upper troposphere and lower stratosphere. To provide such a capability, the Perseus unmanned science research aircraft was proposed in 1989. As a first step toward the development of Perseus, a proof-of-concept (POC) demonstrator was constructed and tested during 1990 and 1991. The POC was a full scale Perseus airframe intended to validate… more

Solubility of pllutonium in alkaline salt solutions

Description: Plutonium solubility data from several studies have been evaluated. For each data set, a predictive model has been developed where appropriate. In addition, a statistical model and corresponding prediction intervals for plutonium solubility as a quadratic function of the hydroxide concentration have been developed. Because of the wide range of solution compositions, the solubility of plutonium can vary by as much as three orders of magnitude for any given hydroxide concentration and still remai… more

Identification, definition and evaluation of potential impacts facing the US electric utility industry over the next decade. Final report

Description: There are numerous conditions of the generation system that may ultimately develop into system states affecting system reliability and security. Such generation system conditions should also be considered when evaluating the potential impacts on system operations.

D0 Solenoid Upgrade Project: Chimney LN2 Radiation Shield Attachment Area Calculation

Description: A short calculation was done to check the attachment method of the radiation shield to it's LN2 cooling tubes. The case considered was only for the obround chimney section. The proposed attachment method was to use 1/8-inch plug welds spaced every 5-inch along the length of the shield. The calculations were done conservatively for 6-inch spacing between plug welds. The criteria used was that the LN2 shield warmest temperature be less than 2 K above the temperature of the LN2 fluid. Using a very… more

D0 Solenoid Upgrade Project: Rectangular Liquid Helium Tube, Miscellaneous Information

Description: This engineering note contains miscellaneous information about the rectangular liquid helium supply tube for the D-Zero solenoid. The information is fairly superficial, but could be used as a starting point for a future engineer who is going to specify and puchase the tubing. The chimney contains 4 conductors attached to an aluminum liquid helium supply tube. Because good thermal contact is desired, the tube will have flat sides. Aluminum is chosen to match the thermal contraction coefficient o… more
