A rapid scanning low noise spectrometer for study of sunspot spectra
Abstract
A rapid high resolution photoelectric spectrometer designed for the study of sunspot spectra is described. The spectrometer employs an on4ine computer for signal integration, and to reject scans that are contaminated by false light due to `seeing'. The apparatus is installed at the Gornergrat, Switzerland, at a height of 3090 metres. An example of its performance is given.
