A breeding blanket design for the tritium production ICF reactor SIRIUS-T is presented. The blanket consists of alternating layers of beryllium multiplier and lithium breeder/coolant with vanadium alloy structure. A tritium breeding ratio of 1.9 can be achieved for the optimum layered configuration with lithium enriched to 90% 6Li. An optimum coolant routing scheme is utilized to achieve adequa...

Because of its unique properties, beryllium has become widely used in a variety of industrial applications, including inertial guidance systems, turbine rotor blades, laser tubes, rocket engine liners, springs, aircraft brakes and landing gear, ball bearings, injection and blow mold tooling, electrical contacts, automotive electronics, X-ray tube windows, spark plugs, electrical components, cer...

In a recent experimental study program involving X-band waveguide components, various factors affecting RF resistivity were investigated. Specific results of this investigation included: l) the successful reduction of the RF resistivity of conventional beryllium copper castings by electroplating with higher conductivity metals, 2) decreasing RF resistivity by lowering surface roughness, 3) the ...

OBJECTIVES Exposure-response relations for beryllium sensitization (BeS) and chronic beryllium disease (CBD) using aerosol mass concentration have been inconsistent, although process-related risks found in most studies suggest that exposure-dependent risks exist. We examined exposure-response relations using personal exposure estimates in a beryllium worker cohort with l...

In this study the interaction of energetic oxygen ions with the beryllium-tungsten alloy Be2W is investigated by depth-resolved X-ray photo-electron spectroscopy (XPS). A 4 nm tungsten layer is deposited on polycrystalline beryllium. By alloying at 900 K for 60 min Be2W is formed. In successive steps oxygen ions are implanted with 500 and 1000 V acceleration voltage with a fluence of 5 · 1014 c...

Chronic beryllium disease (CBD) is a rare disease characterized by diffuse interstitial pulmonary granulomatosis. We report a case of CBD which exhibited marked improvement both subjectively and objectively following pulse therapy. The patient was a 36-year-old man whose chief complaint was dyspnea and a dry cough. Since July 1990, the patient had been working in the development of an automatic...

The KLOE experiment has collected 2.4 pb of integrated luminosity during the commissioning of the DAΦNE φ-factory in 1999. The performance of the detector has been studied using the φ → KLKS decays collected during this period, yielding also first measurements of relevant K parameters such as masses and lifetimes. A clean KS → π π sample is used to select KL → ππ CP-violating decays and KL → KS...
