Laser Target Vacuum Chamber


An iron metal cylindrical chamber with a rectangular base. The Chamber has a removable lid that is affixed with six knurled nuts. At the centre of the lid is a small (~3 cm diameter) window. Visible within the chamber is a machined aluminum sample holder.

Protruding from one end of the chamber is a metal hose ending in a coupling nut. This is used to attach the chamber to a vacuum system and mass spectrometer.

This chamber was part of the laser-heated rare gas mass spectrometer. It held a number of mineral samples in a machined aluminum disk. The samples were heated individually to release the entrained gas. The chamber was under vacuum. The gas released from the sample was drawn through a mass spectrometer for analysis.


Very good. The sample chamber has minor corrosion on several outside surfaces.

This artefact was acquired by the UTSIC collection in the summer of 2015, from the decommissioned lab of Prof. Derek York (1936-2007), a geophysicist at the University of Toronto.
