Static low-energy ion scattering

Abstract A new type of energy analyzer (EARISS) has been developed that makes a very efficient use of the back-scattered ions. This enables the use of extremely low ion doses (“static” conditions). For instance, a spectrum of an Au 20 Pd 80 alloy could be obtained with a dose as low as 100 pC. Together with measurements on HOPG(0001) it demonstrates the new possibilities for LEIS using EARISS.
