A system for the support and management of search for documents is presents. The MR imaging system also includes a cryocooler connected to the heat pipe to cool the heat pipe and the cryogen, wherein the coil form is comprised of a thermally conductive material in which eddy currents are substantially reduced during operation of the at least one gradient coil. The wheel is configured to accommodate the in-wheel actuator in an inner space and is driven by the rotational speed of the output shaft to rotate. The bottom surface of the groove curves longitudinally and transversely, with a maximum curvature of about 4 microns. Multidirectional movements of the upper plate and the lower plate facilitate placement and securing of the magazines.
