3. IL DETECTION

3.1. Detection specifics

IL detection is sensitive to the fluctuations and drift of the acceleration voltage Vp. In order to measure deltaE with an error of 0,5 eV (Part 5) the level of fluctuations and drift of Vp should not be higher than respectively 50 mV and 0.1 V/h. The experience with commercial AES spectrometers proves that such levels are achievable given a good cicuitry adjustment in the electron gun power supply.
