Tests of a diamond field-assisted positron moderator
(
Elsevier
, 2002 , Conference Paper)
Diagnostic studies have been performed on a 70 μm thick diamond film with a view to its development as a possible field-assisted moderator (FAM) for slow positron emission. The film was coated on one side with a 200 nm ...
Re-emission of slow positrons from tungsten at elevated temperatures
(
Elsevier
, 2002 , Conference Paper)
A series of measurements have been made on the dependence of the intensity and energy spectrum of slow positrons re-emitted from polycrystalline tungsten foil held at temperatures of up to 500 °C. Irrespective of target ...
