This official picture by UKAEA was used in the UKAEA Annual Review 2000/2001 and in the Safety, Health and Environment Report 2000/2001. It shows me looking into the collection lens of the Thomson scattering diagnostic on the MAST fusion experiment. The view is on the side of the lens facing the plasma. During a plasma discharge the lens images the scattered light from the plasma onto optical fibres. The fibres transfer the light to a spectrometer. For the picture the fibres were back-illuminated, which made the fibre visible in the lens. The top array is the high-resolution Ruby system. The bottom array is multi-time Nd:YAG system.
This official picture by UKAEA was used in the UKAEA Annual Review 2001/2002. From left to right it shows Jian Qin, me and Andrew Kirk in the MAST control room analysing a plasma discharge.
These four pictures were taken by the high-speed camera on the MAST fusion experiment. They show MAST discharge 2948 subsequently during low confinement (27 ms), high-confinement (29 ms, 31 ms) and during an edge instability (33 ms).
This picture was taken by Mike Walsh inside the MAST vessel. We were inside the vessel to calibrate the Thomson scattering diagnostic. We back-illuminated the optical fibres to create images of the fibre surfaces inside the vessel. This allowed us to determine the exact location of the source of the scattered light.
This picture was taken during my viva of my dissertation "Density gradients in spherical tokamak plasmas" at Eindhoven University of Technology. The viva started of with a five-minute lekenpraatje.
This picture shows me the day after my viva in front of Rijnhuizen castle at the FOM-Institute for Plasma Physics.
