The 33S1-33P0,1,2 transitions in helium-like oxygen have been observed in a foil-excited beam using a 'Doppler cancellation' light-enhancement technique applied to a grating spectrometer. The wavelengths of these transitions were measured at oxygen b

The lifetimes of the 1s2p 3P1 levels of helium-like magnesium and aluminium have been measured by the beam-foil decay curve technique. The 1s2-1s2p transitions were observed with a curved-crystal X-ray spectrometer. Decay curves taken under systemati

A camera has been developed for low light level, high resolution viewing and uses a HeNe laser beam raster-scanned across the field-of-view. By synchronously detecting the reflected light with a photomultiplier the subject can be reconstructed in a v

We report the first observation of a laser-induced $M1$ transition in a fast beam. This new method has been applied to a measurement of the $F=\frac{1}{2}\ensuremath{-}\frac{3}{2}$ and $F=\frac{3}{2}\ensuremath{-}\frac{5}{2}$ hyperfine components of

Radiation emitted from silicon beams at 35, 38 and 45 MeV excited by passage through thin carbon foils has been studied in the range 3-9 AA using a curved-crystal X-ray spectrometer. More than 100 lines have been observed, of which only one quarter h

A simple and practical arrangement of coupling lenses for viewing a fast beam light source with a grating spectrometer is shown to provide very efficient light collection with good spectral and spatial resolution together with a simple procedure for

The wavelengths of the 1s2s 3S1 - 1s2p 3P0,2 transitions in He-like Si12+ have been remeasured to be 87.86 ± 0.01 nm and 81.48 ± 0.01 nm. The use of Rydberg lines for the calibration of fast beam spectra is discussed.
