Experiments carried out on the MAGPIE generator to study the optical and x-ray emission from carbon and deuterium fibres are presented. The generator was operated at 1.4 MV, peak current of 1 MA, rise time 150 ns. Carbon fibres of diameter of 33 {mu}m and 300 {mu}m were used. The following diagnostics were used: single pass interferometry, two frames schlieren photography, optical and x-ray streak cameras, four frames x-ray camera, single frame optical camera and time integrated pinhole camera. Rogowski coils and capacitive divider were used to monitor the electrical signals of the generator and the plasma. Time resolved measurements of x-ray emission were performed with a four frame x-ray camera. Each frame with a set of three filtered pinholes was used. The novel feature of this measurement is the employment of an optical streak camera with a set of slits arranged along the fibre axis, but displaced in the radial direction. This permitted us to study the axial and radial movement of the plasma regions that are emitting in the visible part of the spectra. Correlation between these regions of the plasma and the location of x-ray hot spots is discussed. Comparison between carbon and deuterium fibres is presented.
