Results of optimisation and simulation of Protein crystallography guide by Kaspar Hewitt Klenø

Contents

1 Introduction

1.1 Guide parameters and instrument layout

The guide is a simple straight guide with a constant square cross section. Guide width is 10 cm. The guide has a length of 156 m.

1.2 Notes on results

The divergences and wavelengths requested in the design criteria makes this a rather simple transport problem. Since it is a long, straight, thin guide, it is trivial to curve it to eliminate the direct line of sight from moderator to sample, if so desired.
