The accuracy of the field strength measurement in rotational single sheet t
esters (RSST) has been investigated by means of both finite clement calcula
tions and measurements on the built set-up. Shielding laminations should be
used above and underneath the actual sample in order to obtain a two-dimen
sional and homogeneous magnetization and to measure the field strength accu
rately. (C) 2000 Elsevier Science B.V. All rights reserved.
