Abstract
A new electro-produced pulsed slow positron facility is now in operation at the Institute for Storage Ring Facilities at Aarhus (ISA). Around 30,000 p ositrons/pulse are routinely produced at a frequency of 12 Hz. With the use of a buncher a pulse length of around 10 ns has been obtained. A program o f positron trapping and cooling is in progress with the possibility to effi ciently produce a slow positron microbeam. (C) 1999 Elsevier Science B.V. A ll rights reserved.
