This is how our system interacts with the larger PISCES rig. This is a 12" conflat flange which has had three 2.75" conflats and one 6" conflat welded to it. The 2.75" flanges are used for other instruments while the 6" flange is what is used to mount the manipulator. This flange will be permanently mounted to the rig with only the 6" flange being removed to allow for maintenance.
This adapts the 6" conflat on the main flange to the 4" mount on the manipulator. The 4" side will be perminatly mounted to the 4" mount on the manipulator. This adaptor is necessary to allow for full bench assembly. Because the Instrument Assembly is a larger diameter than the hole in a 4" flange the adaptor allows us to use the 6" flange which is large enough for the instrument assembly to go through.
This manipulator was one that our sponsor already had on hand. We believe this maniulator to be more than 15 years old and required some cleaning. Being this old there were no CAD files so we created a crude but practical model. The manipulator uses welded bellows to keep vacuum while moving through its 16" stroke, It is powered by a NEMA 23 Stepper motor which uses a worm drive to prevent back driving if power is lost, and the linear motion is generated using a lead screw
This assembly passes through the Manipulator and mounts to the instrument assembly. The top flange is rotatable to allow for alignment of the scintillator. It also has two water tubes welded into it to allow for water cooling to pass through. There is also a welded passthrough to allow for the Faraday Cup cables.
Here is where the scintillator and faraday cup gets mounted. The bottom has a water cooled block that prevents overheating while the plasma is on.
