© 2019 The Gothenburg ANion Detector for Affinity measurements by Laser PHotodetachment (GANDALPH)has recently been built for measurements of electron affinities (EA)of radioisotopes. A first measurement campaign is aimed towards the determination of the EA of astatine, the rarest naturally occurring element on earth. In this work we present several upgrades of GANDALPH which have been implemented in order to facilitate EA measurements of radioisotopes where only low intensity ion beams (<1 pA)can be produced.
