A new cylindrical mirror analyzer (CMA) was designed to measure the absolute Auger electron yield and to offer the standard spectra in the Auger electron spectroscopy (AES). An ideal logarithmic potential distribution, which is the heart of the CMA, can be attained by only adjusting the location of the potential gap at the both ends of the CMA without using conventional fringing field correcting electrodes. The effects of residual magnetic field was also discussed and the attenuation characteristics of the μ-metal shield was presented.
