Large-Area Neutron Detector
Appearance
Also know as LAND. It is the name of a detector for neutrons installed at GSI.
It is composed of 10 planes of 20 paddles. Each of the paddle has a size of 10x10x200cm and are composed of a sandwich structure of layers of converter (iron) and of plastic scintillator (each with a thickness of 0.5mm). The converters are used to convert neutrons (uncharged particles) in charged particles (detectable by the plastic) through the process of hadronic schowers. Each paddle is read at its two edges by two photomultipliers. It was build in 1992.
A group of research at GSI is named after this detector. They are studying nuclear structure of radioactive (short-lived) nuclei in the light of middle-mass regions.
