The ID of the engaging region of the top-hat catcher (A) is 32 mm, allowing insertion of the adapter nut (C) and device (D) assembly. A 25 mm × 4 mm Viton O-ring engages the rod to the catcher and separates the differential pumping shroud from the rest of the chamber. The nut connects with the rod via M12 internal threads. (b) Setup for the 25 mm OD nozzle rod (E). The GDVN (D) is screwed to the rod via adapter nut (F) with M9 internal threads. The adapter is fastened to the rod with M23 external threads. The magenta arrow represents the X-ray direction. (c) The half-inch nozzle rod and catcher assembly for comparison. |
