Plunger

NSCL assistant professor Krzysztof Starosta adjusts a device designed by Alfred Dewald, an NSCL user from the University of Cologne, that is capable of making highly precise in-flight distance measurements on the sub-micron scale. (A micron is one-millionth of a meter.) The device was used in a first-of-its kind experiment for fast-beam rare isotope research laboratories such as NSCL.
