Abstract
A new apparatus for experimental studies on the positronium negative ions has been developed at the KEK-PF slow positron facility. The ions are emitted into vacuum from the Na deposited surface of a tungsten target bombarded with pulsed slow positrons. The apparatus will allow the study of the process of the Ps− photodetachment when it is combined with the use of an intense pulsed laser synchronized to the positron beam.
