A prototype photon-beam-position monitor has been designed, fabricated and tested at the Taiwan Light Source of the Synchrotron Radiation Research Center. Aluminium was chosen as the material of the blade electrodes due to its low atomic number and high thermal conductivity. The resolution of this photon-beam-position monitor was <±1 µm. The sensitivity of the blade electrode has been measured in situ. Results of measurements for bending-magnet light and undulator light with different gaps are described.

The title compound was synthesized and analyzed by X-ray diffraction, in addition to IR, NMR, visible-UV and mass spectral studies. The coordination geometry about the Tc^V atom is five-coordinate square pyramidal, with four N atoms in equatorial positions and an O atom in the axial position. The Tc=O double-bond distance is 1.664 (5) Å. The two amide Tc-N bond lengths are shorter than the two oxime Tc-N bond lengths. The central six-membered ring has a boat conformation with the Tc-bonded O atom `hanging' above. The intramolecular hydrogen-bond length between the two O atoms of the oxime groups is 2.432 (9) Å. The cyclobutyl C atoms are, more or less, in a square plane.
