Abstract :
Degradation of Secondary Emission Chamber (SEC) efficiencies has been seen in the past. As a result, instruments in use today are built to minimize any such effects. With beam intensities as high as 6×1013 protons per pulse incident on these devices we are again observing significant degradation in SEC efficiencies. In this report we present observations of these effects and methods we have developed to cope with them
