The GALLEX project

The GALLEX collaboration aims at the detection of solar neutrinos in a radio-chemical experiment employing 30 tons of Gallium in form of concentrated aqueous Gallium- chloride solution. The detector is primarily sensitive to the otherwise inaccessible pp-neutrinos. Details of the experiment have been repeteadly descibed before. Here we report the present status of implementation in the Laboratori Nazionali del Gran Sasso (Italy). So far, 12.2 tons of Gallium are at hand. The present status of developments allows to start the first full scale run at the time when 30 tons of Gallium become available. This date is expected to be January, 1990
