Luminous paint paint was used to illuminate Apollo Lunar Module electrical switch tips and painted on control panels of the Lunar Roving Vehicle. The latest generation of the radioluminescent materials is based on tritium, a radioactive isotope of hydrogen with half-life of 12.32 years that emits very low-energy beta radiation. The devices are similar to a fluorescent tube in construction, as they consist of a hermetically sealed (usually borosilicate-glass) tube, coated inside with a phosphor, and filled with tritium. They are known under many names – e.g. gaseous tritium light source (GTLS), traser, betalight. Tritium light sources are most often seen as
On-Line Isotope Mass Separator or to the REX accelerator for acceleration to higher energies. The facility is operated by the ISOLDE Collaboration comprising CERN and 9 European countries. One of the major experiments in ISOLDE is the Miniball-setup. An upgrade of the post-acceleration system is currently on-going, ready to produce energetic Radioactive-Ion Beams (RIBs) of up to 10 MeV per nucleon in 2018. On-Line Isotope Mass Separator The On-Line Isotope Mass Separator, also known as the ISOLDE Radioactive Ion Beam Facility, is a facility located at CERN on the PS Booster. It started operating in 1967 and was rebuilt twice with major upgrades in
