Magnusson is the name given to the UHV rig that we used throught the experiment. It consisty of three chambers - the fast entry chamber (FEC), main chamber and side chamber. The table below details key properties of the UHV ensemple.
Diffusion backed by rotary
Titanium sublimation pump (TSP)
|Diffusion backed by rotary||
Retractable LEED rig
Manipulator consisting of sample stage, x,y,z, theta movement, annealing filament, thermocouple.
Argon ion gun
Mn and Sb K-cells
One of the first tasks undertaken in the project was to fit necesary upgrades to magnusson. These are detailed in the Magnusson upgrade section, which may be navigated to via the links bar on the left hand side of the page.
To enable, for example, roughing of the chambers by the rotary pumps, or use of the Argon ion gun with out damaging the ion pump, a number of valves are present to seal off different parts of chambers and components. A schematic of the valve system is shown below.
