Abstract
In order to study plasma rotation, temperature, and impurity density, a Neon Soft X-ray Spectrometer (NeSoXs) was installed on the Alcator C-Mod tokamak. This spectrometer used a spherically bent mica crystal as the reflective element in order to separate the spectral and spatial information on the receiving CCD. The original NeSoXs was found to have several problems including vacuum quality, camera readout rate, crystal positioning, chamber size, and chamber positioning. In order to remedy these problems, a new system was designed and has been constructed. This system has achieved much better vacuum pumping times (-100 times faster) and is in the process of being installed on the Alcator C-Mod vessel.
