Abstract
A compact 2.0 T superconducting magnet has been developed for use in photoelectron microscopy. The magnet was required to be compact and magnetically well shielded with low stray fields. Because the magnet is for use with a microscope, the working volume can be small. A small volume implies that the stored magnetic energy is low, and with low stray fields, it makes the magnet safe while operating and during quench events. The magnet is a cryogen free design that uses a diamond loaded vacuum grease for current lead encapsulation and cooling. To make as small a coil as possible, a new coil winding method was developed that does not require solder joints between pancake windings. We show that a low temperature Sn/Bi/Ag eutectic solder can be used for connecting the input leads in this application.
