Demand for hobbyist atomic clock development
Problem
Users seek to build affordable atomic clock references that sit between TCXO and rubidium in price and phase noise, using readily available gases, and are intrigued by the potential of optical atomic clocks for precision measurements such as gravity detection.
Pain points
- High-cost atomic clocks are difficult to realize for hobbyists
- Lack of prototypes using common gases (e.g., neon, nitrogen, mercury) for atomic clocks
- Desire for a compromise between TCXO and Rb to improve phase noise
Questions to verify
- Have you ever attempted to build an atomic clock or similar device yourself?
- When selecting a reference, which performance metric do you prioritize: cost, phase noise, or stability?
- Would you be willing to participate in or fund research developing atomic clock prototypes using common gases?

Somewhat off-topic:I’ve often wondered if a hobby-class atomic clock can be built with “a less accurate gas” that is easy to excite and measure in a feedback loop simply because it’s available in a handy package that lends itself for experimentation without having to mess with melting glass and bottles of pressurised gas. E.g. neon, nitrogen or mercury vapour.The reason I’m asking is because in RF we often need a stable reference, and these come in a clear $ for phase noise relationship: RC, LC, xtal, TCXO, GPSDO, YIG, Rubidium, …Price-wise, all atomic clocks come after Rubidium. But would it be possible to build an atomic clock that sits between TCXO and Rb both for price and phase noise, by employing a non-exotic gas in a readily available lamp?

A clock, not only to measure time, but gravity as well. It’s impressive that it can measure time dilation due to a height difference of 5mm

The most impressive part for me is:Optical atomic clocks at the 10^-19 level are so precise they can detect the slowing of time caused by gravity over height differences of millimeters.
