Deformations in the walls of a hollow superconducting cylinder trapping a magnetic field change the strength and homogeneity of the field. The influence of such distortions has been studied numerically. The results allow an estimate to be made of the accuracy to which a cylinder has to be machined t

IN some previous papers ~ 3 by this author certain properties of a Nb3Sn hollow cylinder are reported. Additionally, the temperature dependence of the trapped field was investigated as this gives several relations to the Anderson-Kim theory. For conversion of the values to be measured into electrica
THE author has recorded the decrease of a field trapped in a Nb3Sn hollow cylinder with increasing temperature, and found the trapped field to be approximately proportional to (1 -T/Te). In the range of field strength examined, the relation ~z = J~(H + Bo) was followed approximately; the resulting q
