CHROMATE INHIBITION OF THE LOCALIZED CORROSION OF ALUMINUM: MEASUREMENTS OF ELECTROCHEMICAL TRANSIENTS.

Description: We investigated the inhibition by chromate ions of the localized corrosion of aluminum by electrochemical transient measurements. In agreement with other work, the measurements demonstrated that chromate is a cathodic inhibitor for aluminum in open circuit. The reduction of hexavalent chromium to trivalent chromium is assumed to take place on catalyzed sites of the surface. The resulting products inhibit oxygen reduction reactions at these sites, thereby retarding pitting corrosion.

Clean Air Act Issues in the 107th Congress

Description: Revisions to the air quality standards for ozone and particulates, promulgated by the Environmental Protection Agency in 1997, may also command renewed attention in the 107th Congress. The standards were challenged in the courts, and implementation is currently in limbo, pending resolution of appeals to the Supreme Court. The Court heard oral arguments November 7, 2000, and a decision is expected in spring 2001. The decision is likely to stimulate congressional oversight, and perhaps legislatio… more

Common Mode Rejection Calculations on the Debuncher Upgrade

Description: The 4-8 GHz Transverse Debuncher Cooling Systems are power limited. Misalignments and imperfections in the transverse pickup arrays will generate a longitudinal signal in addition to the betatron signal. This longitudinal signal can use up a significant fraction of the precious TWT power if the imperfections are large enough. This note will summarize calculations of the contributions to the longitudinal signal observed in the transverse systems of the 4-8 GHz Debuncher slow-wave pickup arrays d… more

Computational Simulations of High Intensity X-Ray Matter Interaction

Description: Free electron lasers have the promise of producing extremely high-intensity short pulses of coherent, monochromatic radiation in the 1-10 keV energy range. For example, the Linac Coherent Light Source at Stanford is being designed to produce an output intensity of 2 x 10{sup 14} W/cm{sup 2} in a 230 fs pulse. These sources will open the door to many novel research studies. However, the intense x-ray pulses may damage the optical components necessary for studying and controlling the output. At t… more

Concept of Operation for Waste Transport, Emplacement, and Retrieval

Description: The preparation of this technical report has two objectives. The first objective is to discuss the base case concepts of waste transport, emplacement, and retrieval operations and evaluate these operations relative to a lower-temperature repository design. Aspects of the operations involved in waste transport, emplacement and retrieval may be affected by the lower-temperature operating schemes. This report evaluates the effects the lower-temperature alternatives may have on the operational conc… more

Contract Management: Purchase of Army Black Berets

Description: Testimony issued by the General Accounting Office with an abstract that begins "The Army's decision to issue black berets to all of its forces in just eight months placed enormous demands on the military's procurement system. To meet this challenge, the Department of Defense (DOD) increased the domestic supplier's production, awarded contracts to known foreign sources, and procured berets from additional sources. This testimony discusses DOD's contracting strategy, including (1) the contracting… more

Creating Ensembles of Decision Trees Through Sampling

Description: Recent work in classification indicates that significant improvements in accuracy can be obtained by growing an ensemble of classifiers and having them vote for the most popular class. This paper focuses on ensembles of decision trees that are created with a randomized procedure based on sampling. Randomization can be introduced by using random samples of the training data (as in bagging or arcing) and running a conventional tree-building algorithm, or by randomizing the induction algorithm its… more

Development of Lower Energy Neutron Spectroscopy for Areal Density Measurement in Implosion Experiment at NIF and Omega

Description: Areal density ({rho}R) is a fundamental parameter that characterizes the performance of an ICF implosion. For high areal densities ({rho}R> 0.1 g/cm{sup 2}), which will be realized in implosion experiments at NIF and LMJ, the target areal density exceeds the stopping range of charged particles and measurements with charged particle spectroscopy will be difficult. In this region, an areal density measurement method using down shifted neutron counting is a promising alternative. The probabilit… more
