HOW TO USE THIS DOCUMENT 
This document is a compilation of drawings for the diffusive mixing beamline assembly 
described in Chapter 4 of my dissertation. 
The first drawing is an overview of the entire assembly. The parts list provides page numbers for 
detailed drawings of each subassembly. 
The parts list of each subassembly drawing provides page numbers for dimensioned drawings of 
each custom part included in the assembly, along with vendor information and part numbers for 
commercial parts. 
 
All custom parts described here were designed and drawn by George Calvey and me.
