| Research Abstract |
An ion plasma confined in a compact trap system is Coulomb crystallized near the absolute zero temperature. The emittance of the crystallized ion plasma is close to the ultimate limit, far below those of any regular ion beams. An ion beam of extremely low emittance becomes available. Such ultra-low emittance beams, even if the current is low, can be used for diverse purposes including precise single ion implantation to various materials and for systematic studies of radiation damage effects on semiconductors and bio-molecules.
We have designed and manufactured a linear Pual trap system optimized to experiments on the extraction of Coulomb crystals. We also have developed a transvese distibution measuremnt system for ultra-low emittance beams. By systematic numerical simulations, it is confirmed that ultra-cold ions can be extracted without serious heating.
