[time-nuts] Question for the cesium nuts.

[Rob Kimberley]

The only people I know making Cs now are Symmetricom (the old Datum/FTS +
recent Agilent acquisition), FEI (although they don't think they make many
now), and Temex in France. Heard rumours of some being made in Japan, but
not sure if and who. The Russians seem to concentrate on H2 Masers (Kvarz,
and Vremya).

Anyone know of others??

Which begs the question of; who's cesium standard will we buy in surplus
market?

Besides you guys (Symmetricom), who is building Cesium standards that
haven't yet been absorbed by Symmetricom? (note this is not meant to be
derogatory).

Certainly most if not all the 5060, 5061, and 5062 are either dead or close
to it. Excluding those that have had their CBT's replaced or properly stored
and regularly pumped down, or just lucky.

The 5071's have yet to make an appearance on eBay at levels I would consider
paying.
