GENERAL DESCRIPTION
The loader can manually load and unload small samples into the SDB
/ SEM. The loader is connected to the specimen chamber of the SDB
/ SEM and also integrated into the main vacuum system hardware
and software.
The loader consists of a loading rod with set slide and parking
position, a vacuum chamber for loading and unloading the sample
carrier (with sample) onto a bayonet fitting located at the end of the
rod. A gate valve seals the vacuum of the SDB / SEM specimen
chamber and can only be opened when the vacuum of the loader
chamber is correct, this being indicated by a 'OK' labeled LED
prompted by an electrical and mechanical interlock.
The sample carrier can be entered into the main SDB / SEM
specimen chamber by way of the rod and released by the rotating
motion of the rod at a predetermined position on the stage adapter.
