Temperature Furnace

A complex high-temperature furnace has been produced from presintered α-Al2O3precompacts. The furnace is designed for the Mar345 imaging-plate detector system. Up to now, the design complexity of ceramic parts has been limited by the difficulty of machining hard ceramic materials or by the moulds used in hot-pressing and casting. However, the machining of soft presintered ceramic materials enables the realisation of much more demanding designs, provided that the final sintering shrinkage of the ceramic is homogeneous and predictable. The design of the furnace and its realisation and application in an X-ray diffraction study with synchrotron radiation are presented.

Imaging Plate Detector

A diffraction system has been constructed at the Synchrotron Radiation Centre at Ritsumeikan University, in which a wide-band parallel X-ray beam is produced by reflection from the depth-graded multilayer monochromator. The band width is 600 eV and the monochromator is useful in the photon energy range from 6500 to 7700 eV. In diffraction patterns of an oscillating single crystal recorded using the beam, Bragg reflections appear in an elongated form on an imaging-plate detector and, if the absorption edge of an atom in the crystal is included in the band, a characteristic intensity profile is seen due to anomalous dispersion. As an application of the system, the absolute configuration was determined for a newly synthesized compound, 4-(1-hydroxyethyl)phenylferrocene, C18H18FeO, with an enantiomorphic structure, choosing the Fe atoms as anomalous scatterers. In the intensity profiles of the Friedel pairs of reflections, clear contrast between the pair was observed at the absorption edge, leading unequivocally to theSform. Further possible application of the wide-bandpass parallel beam is discussed.

Highly Sensitive

The “Imaging Plate”(IP) is a highly sensitive image recording plate for X-ray radiography. It has been ascertained that the IP has superior properties and high practicability as an image recording material in a TEM. The sensitivity, one of the properties, is about 3 orders higher than that of conventional photo film. The IP is expected to be applied to low dose techniques. In this paper, an estimation of the quantum noise on the TEM image which appears in case of low electron dose on the IP is reported.In this experiment, the JEM-2000FX TEM and an IP having the same size as photo film were used.Figure 1 shows the schematic diagram of the total system including the TEM used in this experiment. In the reader, He-Ne laser light is scanned across the IP, then blue light is emitted from the IP.
