Advances in lithographic techniques have enabled the manufacture of instruments with minute features. We are taking advantage of these tecniques to design, build, and test a new plasma spectrometer-an instrument that measures the flux of ions or electrons as a function of energy. This new spectrometer will be about the size of a sugar cube. This small size enables its use on microsatellites for space physics applications and in smart wall tiles for fusion-relevant measurements in a tokamak.
Projects in diagnostic development include design and testing of the spectrometer and related components.
