A schematic diagram of the endstation vacuum system, showing the detector (orange), beamstop module (purple), flight tubes (green) with moveable sections indicated by opposing square brackets, silicon nitride window (pale blue) and sample position (red triangle). Gate valves are indicated by rectangles with a cross through them. Pumps are indicated by squares with a circle and a right-facing arrow; roots pumps have two perpendicular lines inside the centre circle, turbomolecular pumps have a horizontal line with multiple cross hatches, and scroll pumps have a small arrow on the left-hand side. |
