C, Particles and fields, 85 (2) (Art N° 202) | Abstract: | We present a coil system designed to generate a highly uniform magnetic field for the n2EDM experiment at the Paul Scherrer Institute. It consists of a main B-0 coil and a set of auxiliary coils mounted on a cubic structure with a side length of 273 cm, inside a large magnetically shielded room (MSR). We have assembled this system and characterized its performances with a mapping robot. The apparatus is able to generate a mu 1 mu T vertical field with a relative root mean square deviation sigma(B-z)/B-z=3 x 10(-5) over the volume of interest, a cylinder of radius 40 cm and height 30 cm. This level of uniformity overcomes the n2EDM requirements, allowing a measurement of the neutron Electric Dipole Moment with a sensitivity better than 1 x 10(-27)ecm. | Notes: | Lefort, T (corresponding author), Univ Caen Normandie, ENSICAEN, LPC Caen UMR6534, CNRS,IN2P3, F-14000 Caen, France.; Bouillaud, T; Pignol, G (corresponding author), Univ Grenoble Alpes, LPSC IN2P3, CNRS, IN2P3, F-38026 Grenoble, France. thomas.bouillaud@epp.phys.kyushu-u.ac.jp; lefort@lpccaen.in2p3.fr; guillaume.pignol@lpsc.in2p3.fr |
