摘要：In instruments such as Wien filters, electrostatic and/or magnetic pole piecesmust be mounted on and secured to a supporting structure with a very high degree ofdimensional precision, usually by brazing. To that end, a fixture is provided for holding

the parts to be assembled in precise relationship and to press the pole pieces intoengagement with the supporting structure while the securing operation is being carriedout. The pressing is accomplished by a gravity-produced force which is, therefore,independent of positional accuracies caused by very high temperatures, such as areencountered during brazing.
