Patent Number: 
Section: claims

1. An apparatus, comprising:a first spooler section;a segmented rolling floor comprising a first end attached to said first spooler section, said first spooler section configured to wind up a section of said segmented rolling floor during use; anda second spooler section attached to a second end of said segmented rolling floor. 2. The apparatus of claim 1, further comprising:a nozzle system penetrating through an aperture in said segmented rolling floor. 3. The apparatus of claim 2, further comprising:a beam path from an accelerator, along a beam transport line, though a rotatable section of said beam transport line, and through said nozzle system. 4. The apparatus of claim 3, further comprising:a gantry attached to said rotatable section of said beam transport line; anda mechanical connection forcing movement of said segmented rolling floor with rotation of said gantry. 5. The apparatus of claim 3, said segmented rolling floor further comprising:an upper section directly above a patient position, said patient position in said beam path. 6. The apparatus of claim 5, said segmented rolling floor further comprising:a vertical section at least five feet in length. 7. The apparatus of claim 5, further comprising:an X-ray imaging system penetrating through said segmented rolling floor. 8. The apparatus of claim 1, said first spooler section positioned above a plane of a floor coplanar with a walkable plane surface section of said segmented rolling floor, said second spooler section positioned below the plane of the floor. 9. An apparatus, comprising:a first spooler section;a segmented rolling floor comprising a first end attached to said first spooler section and a curved rolling wall section, said first spooler section configured to wind up a section of said segmented rolling floor during use. 10. A method, comprising the steps of:providing a segmented rolling floor; andspooling said segmented rolling floor onto a first rolling floor spool, said first rolling floor spool attached to a first end of said segmented rolling floor; andunwinding said segmented rolling floor from a second rolling floor spool, attached to a second end of said segmented rolling floor, during said step of spooling. 11. The method of claim 10, further comprising the step of:positioning a nozzle end of a nozzle system through an aperture in said segmented rolling floor. 12. The method of claim 11, further comprising the step of:co-moving said nozzle system and said segmented rolling floor. 13. The method of claim 12, further comprising the step of:sequentially transporting positively charged particles from an accelerator, along a rotatable beam transport line, and through said nozzle system. 14. The method of claim 13, further comprising the step of:a gantry rotating said rotatable beam transport line at a rate of said step of spooling said segment rolling floor.
