Abstract

A flat field grating spectrometer has been installed on Massachusetts Institute of Technology’s Alcator C-MOD tokamak. This spectrometer is being used to measure and monitor the presence of impurity ions. The spectrometer employs a variable space grating with a spacing of 2400 lines/mm that covers the 10-70 Å wavelength band. The spectrometer has a time resolution of about 5 ms. Here we present results of the Alcator C-MOD experiments conducted during spring of 2010. The typical spectra contain lines from such elements as boron, argon, calcium, fluorine, and tungsten. We will also discuss how this work can be integrated into a high school classroom as a means to educate students about energy research as well as atomic and plasma physics. This will also equip students with the understanding and skills of how science and research are accomplished in a professional setting.
