The first attempt to accelerate each of two opposing beams of protons to 3.5 TeV apiece failed when a power supply shut down inadvertently and a new magnet-protection system tripped, dumping the beam.
The SIMS technique bombards the lunar samples with a primary ion beam that allows the researchers to separate the ions with a magnet, depending on the charge.
