Enhanced durability and reactivity for zinc ferrite desulfurization sorbent

Description: AMAX Research Development Center (AMAX R D) has been investigating methods for enhancing the reactivity and durability of the zinc ferrite desulfurization sorbent. Zinc ferrite sorbents are intended for use in desulfurization of hot coal gas in integrated gasification combined cycle (IGCC) or molten carbonate fuel cell (MCFC) applications. For the present program, the reactivity of the sorbent may be defined as its sulfur sorption capacity at the breakthrough point and at saturation in a bench-… more

Vibration analysis of APS magnet/support systems based on the finite element method

Description: Prediction of the dynamic response of APS magnet/support systems requires knowledge of the free vibrational characteristics, including natural frequencies, modes, and modal damping ratios. A preliminary dynamic analysis of the magnet/support system of a typical section of the APS storage ring, as presented in the APS Conceptual Design Report, was performed to gain insight. The preliminary analysis is based on the assumption that the support girder could be considered rigid relative to the stiff… more

DRCELL: A software package for drift chamber cell design

Description: Designing a drift chamber cell geometry which optimizes resolution and two track separation is not a straightforward task. This paper describes a software package which helps visualize the behavior of drifting electrons within the cell under the influence of electric and magnetic fields. Histograms of chamber pulse shapes and arrival times may be generated. In addition, a calculation of the gas gain is performed. The package presently uses drift velocity, drift angle, gain, and dE/dx parameteri… more

NUMO: A new (D,T) fusion diagnostic technique

Description: A NeUtron MOnochromator, NUMO, for (D,T) fusion diagnostics is described. The monochromator consists of CH/sub 2/ (n,p) converter foil, a sector-magnet monochromator and Faraday cup detector. This system can be used to study some details of (D,T) fusion reaction history. 6 refs., 5 figs.

D0 Carriage Roller Bearing Measurements

Description: All of the ordered Tychoway rollers, to be used under the cryostat carriages on the center beam, have to be modified to accommodate a keyed way used to guide the cryostat along these same ways. A 0.320 x 0.406 inch notch is machined along one of the longer lower edges in order to create a 0.640 x 0.406 inch keyway when two of these notched rollers are bolted together (side by side) for installation. This keyway will fit over a .635 x .375 inch key, which is inserted into the ways. Due to the cl… more

V-TOUGH: An enhanced version of the TOUGH code for the thermal and hydrologic simulation of large-scale problems in nuclear waste isolation

Description: The TOUGH code developed at Lawrence Berkeley Laboratory (LBL) is being extensively used to numerically simulate the thermal and hydrologic environment around nuclear waste packages in the unsaturated zone for the Yucca Mountain Project. At the Lawrence Livermore National Laboratory (LLNL) we have rewritten approximately 80 percent of the TOUGH code to increase its speed and incorporate new options. The geometry of many problems requires large numbers of computational elements elements in order… more

User computer system pilot project

Description: The User Computer System (UCS) is a general purpose unclassified, nonproduction system for Mound users. The UCS pilot project was successfully completed, and the system currently has more than 250 users. Over 100 tables were installed on the UCS for use by subscribers, including tables containing data on employees, budgets, and purchasing. In addition, a UCS training course was developed and implemented.
