We present experimental results of a version of the Choppertron microwave generator designed to work with the high emittance beam of the Advanced Test Accelerator (ATA). Simulations showed that a 800-A, 120 {pi} cm-mrad beam (typical of ATA), could produce 800 MW of rf (11.4 GHz) power using two 12-cell, traveling-wav…

During tensile creep of a hot isostatically pressed (HIPed) silicon nitride, the volume fraction of cavities increases linearly with strain; these cavities produce nearly all of the measured strain. In contrast, compressive creep in the same stress and temperature range produces very little cavitation. A stress expone…

The variation of intensity of the photostimulated luminescence (PSL) of BaFCl:Eu2+ after ultraviolet irradiation with temperature has been investigated. The results show that the PSL intensity is independent of temperature in the readout process, but the storage ability is temperature dependent. The measurements suppo…

Abstract A crystal structure is usually described as the union of sets of symmetrically equivalent atoms, i.e. as the union of orbits. During a continuous or nearly continuous phase transition, symmetrically equivalent atoms of a crystal structure may become inequivalent, their site symmetries may be reduced, or both…

Croconic acid, H 2 C 5 O 5 , is readily oxidized. This may be attested by decolorization of the solutions and by observation of oxalic acid complexes. The oxidation products are identified by 13 C NMR spectroscopy as oxalic and mesoxalic acids, and experimental conditions are specified. The oxidation process requires…

The crystallization and fractal formation in a-Ge/Au have been studied by in situ TEM and HREM. It was demonstrated that both the crystallization and the fractal formation depend on the continuity of the Au underlayer and the thickness of the a-Ge layer. As the Au film changed from semicontinuous to discontinuous, the…

Abstract Morphological aspects of the evolution of a gas ‐ solid interface during typical CVD processes are presented, as well as a continuum model of CVD growth. A linear stability analysis used determines the effect of reactor conditions on the stability of planar growth. The main focus, however, is numerical soluti…

Abstract The characteristic parameters for three different equation‐of‐state (EOS) theories have been determined for polystyrene and low‐molecular weight polyisoprene using pressure‐volume‐temperature ( PVT ) data. Basically two procedures for the calculation of characteristic parameters were applied. The characterist…

Abstract Glycolysis of poly(ethylene terephthalate) with bisphenol A at high temperature (190°C–230°C) was carried out in an autoclave reactor. Kinetic study on depolymerization of glycolysis was conducted. The reaction temperature and the ratio of bisphenol A to poly(ethylene terephthalate) played the key roles on th…

Leaching of oxytetracycline, oxolinic acid, amoxycillin and the potentiated sulphonamide trimethoprim/ sulphamethoxazote (TMP/SMX) from surface-coated fish-feed pellets, surrounded with either cod liver oil or with calcium-alginate, was investigated. Despite the low water temperature (12°C), losses of amoxycillin, oxy…
