    Description: The PERCIVAL detector is a CMOS imager designed for the soft X‐ray regime at photon sources. Although still in its final development phase, it has recently seen its first user experiments: ptychography at a free‐electron laser, holographic imaging at a storage ring and preliminary tests on X‐ray photon correlation spectroscopy. The detector performed remarkably well in terms of spatial resolution achievable in the sample plane, owing to its small pixel size, large active area and very large dynamic range; but also in terms of its frame rate, which is significantly faster than traditional CCDs. In particular, it is the combination of these features which makes PERCIVAL an attractive option for soft X‐ray science.

    Notes: Results of Monte Carlo simulations of Si and GaAs p-n electron emitters are presented. A single-electron Monte Carlo transport simulation is used to obtain the total number, including avalanche multiplication, of electrons which reach the surface of the semiconductor, as well as the fraction of these which overcome the work function and are emitted into the vacuum. The distribution function is obtained, as well as ensemble average of quantities such as the ionization coefficient. The efficiency of the device is calculated as a function of both the work function and the top conducting channel thickness. The potential performance of GaAs devices is explored via the Monte Carlo simulation, and calculated results for the Si device are compared to published experimental data.

    Notes: Uniform charged liquid-hydrogen drops are produced using the method of field injection electrostatic spraying. This method consists of forming a meniscus of liquid hydrogen at the end of a glass nozzle and injecting charge into the liquid using a sharp electrode raised to a high voltage. A small pressure drop across the nozzle results in a constant volume flow rate of liquid through the nozzle allowing a drop to form and drip off. As the amount of charge injection increases with the raised needle electrode voltage, the drop size decreases due to the increased electrostatic forces compensating for the surface tension forces. As a result, the drops drip off at an increased frequency. Eventually a charged jet forms which in turn breaks up into small uniform charged drops. A detailed description of the experimental apparatus is presented. Experimental results are presented and discussed.

    Notes: Inhibition of fluid flow instabilities in the melt by the axial magnetic field in Czochralski silicon crystal growth (AMCZ) is investigated precisely by a high-sensitivity striation etch in conjunction with temperature measurements. The magnetic field strength (B) was varied up to 4.0 kG, incremented mostly in 0.5-kG/2.5-cm crystal length. The convection flow was substantially suppressed at B≥1.0 kG. A low oxygen level of 2–3 ppm and a high resistivity of 400 Ω cm is achieved in the AMCZ silicon crystals at B≥1.0 kG. Random striations at B=0, characteristic of turbulent convection, assumed progressively a periodicity, indicative of oscillatory convection at 0.35〈B≤4.0 kG. The striation contrast or "intensity'' decreased steadily with the increase in B. At B=4 kG, most of the crystal was free of striations, although some weak, localized periodic striations persisted near the crystal periphery. Spreading-resistance measurement shows, however, a uniform dopant distribution in all crystal sections grown at 0.35〈B≤4.0 kG within a few percent.

    Notes: High-power beams (4–10 W/cm2) of Ti ions have been used to heat Fe and steel substrates to 600–800 °C during high fluence (5×1017/cm2) implantation. Auger sputter depth profiles find a stoichiometric TiC surface layer, about 100 nm deep, graded continuously into both Fe and steel substrates. Secondary ion mass spectrometry of Fe and steels implanted in 13CO atmospheres indicate that the carbon originates from the bulk in carbon steels but from the atmosphere in Fe foils. Transmission electron microscopy reveals a continuous layer of fine-grained (50–100 nm) TiC crystallites in a preferred Baker–Nutting orientation relationship with respect to underlying Fe grains. Abrasive-wear measurements performed with diamond paste (1–5 μm) show the TiC layer on hardened M2 steel is 3–10 times more wear resistant than the substrate. Sliding-wear studies find an extremely durable layer that reduces friction by up to 60%, and increases by 50% the contact-stress threshold of M2 tool steel to boundary lubrication. The metallurgical processes responsible for the TiC layer will be discussed, and the advantages of this high-temperature treatment will be presented.
