D. Segers et al., BEAM HANDLING WITH A PENNING TRAP OF A LINAC-BASED SLOW POSITRON BEAM, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 337(2-3), 1994, pp. 246-252
A Penning trap was constructed at the Ghent LINAC-based slow positron
beam. It allows us to store the positrons without considerable loss in
intensity and to create a quasi-continuous beam so that positron Dopp
ler broadening measurements are possible. Starting from the stored pos
itrons it is also possible to create a pulsed beam with pulse width of
the order of 100 ns so that time-of-flight measurements are possible.
