FURTHER WORK ON THE DESIGN AND IMPLEMENTATION OF A BRIGHT METASTABLE ATOM SOURCE J G Lambourne, M K Odling-Smee, A T Cousins and P Hammond Department of Physics & Astronomy, University of Manchester, Manchester M13 9PL, UK A bright metastable atom source with a low ground state atom density has been designed for use in electron scattering experiments. The metastable atom number density during a beam pulse is estimated to be 10^7 metastable atoms per cm^3 in argon Please click here to view full abstract.
