Limits on likesign dilepton production in nu/sub. mu. / interactions

Description: We have searched for the production of likesign dilepton events (nu/sub ..mu../ + Ne ..-->.. ..mu../sup -/ + e/sup -/ + ...) in a wideband neutrino beam at FNAL using the 15' bubble chamber. We observe no signal above the background arising from conventional sources. We set 90% confidence level upper limits for the production rates of (nu/sub ..mu../ + Ne ..-->.. ..mu../sup -/ + e/sup -/ + ...)/(nu/sub ..mu../ + Ne ..-->.. ..mu../sup -/ + ...) less than or equal to 8 * 10/sup -5/ and (nu/sub ..… more

Elimination of electromagnetic radiation in plasma simulation: the Darwin or magnetoinductive approximation

Description: For many astrophysical and most magnetic fusion applications, the purely electromagnetic modes generated by real as well as simulation ''plasma'' fluctuations are a source of high frequency radiation that is often irrelevant to the physics of interest. Unfortunately, a numerical CFL stability limit prevents either making c infinite or deltat large while using the usual explicit Maxwell's equations for the fields. A modification of Maxwell's equations, which provides implicitly the field compone… more

Determination of somatic mutations in human erythrocytes by cytometry

Description: Flow cytometric assays of human erythrocytes labeled with monoclonal antibodies specific for glycophorin A were used to enumerate variant cells that appear in peripheral blood as a result of somatic gene-loss mutations in erythrocyte precursor cells. The assay was performed on erythrocytes from 10 oncology patients who had received at least one treatment from radiation or mutagenic chemotherapy at least 3 weeks before being assayed. The patients were suffering from many different malignancies (… more

Forced-convection boiling tests performed in parallel simulated LMR fuel assemblies

Description: Forced-convection tests have been carried out using parallel simulated Liquid Metal Reactor fuel assemblies in an engineering-scale sodium loop, the Thermal-Hydraulic Out-of-Reactor Safety facility. The tests, performed under single- and two-phase conditions, have shown that for low forced-convection flow there is significant flow augmentation by thermal convection, an important phenomenon under degraded shutdown heat removal conditions in an LMR. The power and flows required for boiling and dr… more

Nondestructive assay instrumentation for Savannah River Plant reprocessing accountability

Description: We have designed, developed, and calibrated three different types of nondestructive assay systems for the Savannah River Plant (SRP). These systems will be delivered to SRP in 1986 and become part of the nuclear material accounting instrumentation at one of SRP's reprocessing facilities. Among the various types of nondestructive assay systems to be implemented are a neutron counter (Los Alamos National Laboratory - LANL), a four-station calorimeter (Mound Laboratories), a waste solution assay s… more
