  In this paper we report on the development and performance of a cylindrical
mirror analyser electron spectrometer for ion atom collision experiments. A low
cost data acquisition system using Arduino microcontroller has also been
developed and tested. We have measured the Auger emission spectra for various
gaseous targets in collision with 1 MeV proton beams. Relative total Auger
emission cross sections have also been measured for N2 molecular target as a
function of proton energy.
