STUDY OF A LARGE SUPERCONDUCTING HELMHOLTZ PAIR, ILLUSTRATED ON HAND OF THE ZEUS DETECTOR PROPOSAL FOR HERA
A pair of large superconducting coils has been proposed to generate longitudinal homogeneous fields for detector assemblies at future TeV accelerators. The study is based on the requirements of the ZEUS experiment at HERA-DESY, but is typical for the forthcoming class of experiments. The coil's diameter is about 5m, and the required field on the detector (2.25m long, 1.6m diameter) is 1.5-1.8T, with a uniformity of a few percent. A large iron shell surrounds the experiment. A big effort has been made in designing the shape of the iron to demonstrate that the huge attractive force between coils and the net shift force due to the longitudinal iron assymetry can be drastically reduced. Two separate cryostats could then be constructed, thus improving the system accessibility. Some details of the coil's construction are also presented.
