This report concerns the part of the Frascati Laboratorio Fusione Laser activity related to the apparatus (target chamber position, alignment system and diagnostics) to be used in the interaction experiments with the ABC laser system. The diagnostic equipment provides semi-quantitative information on the distribution of energy deposition on the target surface using optical diagnostics, pinhole camera soft X-ray imaging and temperature, charged particles and reflected light measurements. The target positioning and replacing system ATRS can replace one hundred successive targets without breaking off the vacuum conditions. Each target can be placed on the same assigned position within 1 µm, and rotated around an axis by means of micropositioning modules driven by remotely controllable stepping motors. The target alignment procedures start with the "first time firing place", with a precision sufficient to avoid diagnostic realignment in case of loss of later references. The focussing lenses are then positioned and the target aligned for shot operation.
