dc.description.abstract | Rotating collectors and quartz microbalances (QMBs) are used in JET to provide time-dependent
measurements of erosion and deposition. Rotation of collector discs behind apertures allows
recording of the long term evolution of deposition. QMBs measure mass change via the
frequency deviations of vibrating quartz crystals. These diagnostics are used to investigate
erosion/deposition during JET-C carbon operation and JET-ILW (ITER-like wall) beryllium/
tungsten operation. A simple geometrical model utilising experimental data is used to model the
time-dependent collector deposition profiles, demonstrating good qualitative agreement with
experimental results. Overall, the JET-ILW collector deposition is reduced by an order of
magnitude relative to JET-C, with beryllium replacing carbon as the dominant deposit. However,
contrary to JET-C, in JET-ILW there is more deposition on the outer collector than the inner.
This reversal of deposition asymmetry is investigated using an analysis of QMB data and is
attributed to the different chemical properties of carbon and beryllium. | es |
