The Daly detector was designed by N.R Daly in the 1960’s . The design uses a conversion dynode to convert incident ions into electrons. It also separates the multiplication electronics away from the ion beam preventing secondary ion production on the multiplication dynodes. The conversion surface is a highly polished, aluminised metal surface that is … Continue reading An assessment of the linearity of the ion-counting Daly detector and Hamamatsu photomultiplier using NBS U500
