otâqak-e tangol, ~ hobâb
Fr.: chambre à bulles
A tank filled with a transparent liquid that is on the brink of boiling. When a charged particle passes through the liquid, the energy deposited initiates boiling along the path, leaving a trail of tiny bubbles. The bubble chamber is no longer in wide use for particle experiments.
M.E., from O.Fr. chambre, from L.L. camera "a chamber, room."
Otâqak "small room, small chamber," cf. Sogdian ôtâk "place, region," ôtâkcik "local, regional, native" + -ak diminutive suffix.
