Cluster beam source
WebA pulsed laser vaporization cluster beam apparatus has been built which can generate clusters of transition metals. Neutral clusters are detected by photoionization time-of-flight mass spectroscopy. The size distribution of the clusters which are generated has been found to be dependent on expansion conditions such as carrier gas, source ... WebThe Method. To overcome this problem researchers from Swansea University, led by Professor Richard Palmer, developed a new machine called the Matrix Assembly Cluster Source (MACS). MACS differs from a traditional cluster beam machine in two main ways: A frozen, cryo-matrix is used to cool the atoms leading to more efficient cluster formation.
