That's a trap. "Optical molasses". A fountain essentially makes a beam and probes it orthogonal to the beam, where the Dopplar shifts are low. The beam basically makes all the atoms go in a single direction w/ no cross track velocities. Are we speaking to some gas fountain without optics > much like a traditional CS standard? > Paul > WB8TSL As to making one, I'd use stainless Conflat parts from eBay, used commercial pumps, feedthroughs, fittings, etc. You can spend a lot of time trying to leak check home brew stuff.
