Telescoping expansion bellows

A melt extraction system for extracting a melt from a crucible, the melt extraction system comprising:

• a cylindrical housing having a top plate and a bottom plate opposite the top plate, wherein the top plate and the bottom plate have are toroidal and define an opening;
• an extraction vessel disposed, within the cylindrical housing, configured to remove the melt from the crucible, the extraction vessel coupled to a guide plate disposed within the cylindrical housing and between the top plate and the extraction vessel;
• and
• a bellows system coupled to the top plate and the guide plate, the bellows system including:
• a first bellows segment having a first end and a second end opposite the first end, the first bellows segment configured to elastically compress and expand;
• a first plate coupled to the second end of the first bellows segment;
• a first sleeve concentric with the first bellows segment and the first plate, the first bellows segment and the first plate disposed within the first sleeve;
• a second bellows segment having a third end and a fourth end opposite the third end, the second bellows segment configured to elastically compress and expand, the third end of the second bellows segment coupled to the first plate;
• and
• a second sleeve coupled to the first plate, the second sleeve concentric with the second bellows segment and the first sleeve, the second bellows segment disposed within the second sleeve, the second sleeve configured to telescope into the first sleeve.
