The work can conveniently be broken into three parts. In Part I, we discuss very briefly the nature of the reactions and establish what we wish to study; nuclear recoil reactions in solids. The advantage of using ion beams for this intent are many and are discussed. Several disadvantages of ion beams are also considered. From this discussion we are able to establish basic general criteria on which to base the design Part II generally deals with the design and construction of the instruments. In the first half we discuss a number of alternative methods which can be used to achieve the same end without making any decision on which to use. This has the advantage of presenting the possible alternatives in the same light. The second half of this section considers in detail the chosen design, proceeding from the ion source to the target cold finger. In Part III we present an account of our efforts to make the instrument work, and the conclusions we have reached based upon our observations. The section concludes with several recommendations for redesign, especially the vacuum system.
