Largest Magnetic Shield Room in the World Successfully Put into Operation
Engineers and scientists at ZAT together with colleagues from the Jülich Centre for Neutron Science (JCNS) and industry partners have developed, designed and constructed the largest magnetic shield room in the world for the neutron spin echo spectrometer (NSE) at the U.S. neutron spallation source (SNS) in Oak Ridge (USA). The chamber, which is 17 m long, 2.5 m to 5.5 m wide and more than 4 m high, reduces the magnetic fields of the Earth and of other SNS experiments by a factor of 100. Without the room, NSE performance would be dramatically impaired. The development result was published in the highly respected journal “Nuclear Instruments and Methods in Physics Research A” (H. Soltner et al., NIM A 644 (2011) 40–47).
