Project of ultrahigh-vacuum double-crystal monochromator

The project is aimed at the development of ultrahigh-vacuum mechanics and construction of devices with features allowing high-precision work in a warmed-up volume. The fundamental part of projected monochromator is a precise linear motion mechanism, linear stage, which can bear a warming-up in vacuum up to t = 400 degreesC without any change in its parameters. It is the tense friction wave transmission that serves to transfer the motion to the stage in the vacuum volume. The mechanism for precision tuning of the second crystal also has an original design and its compactness allows an easier solution of many design issues concerning the whole monochromator, (C) 2001 Elsevier Science B.V.
