And Americium is not as useful for a timing reference, as it's not as stable as Rubidium and a lot less safe to handle. Otherwise time nuts would hoard cheap smoke detectors :)

- tverbeure 5mo agoI have 2 Rb GPSDOs and a few more OCXO ones, but had never heard of CSAC modules and thought that the inevitable next step would be an HP 5061A Cs clock or later model. So now you have me going to eBay in search one but all it turns up are BM25CSAC carburetors! What are the magic keywords to use in my search?
- geerlingguy 5mo agoSearch for "rubidium clock" or "gpsdo rubidium" and you'll start whittling it down more. It's much harder to find just the CSAC part, unless you're building clocks commercially.
- s0rce 5mo agoAmericium is also chemically different and may not be as practical as cesium and rubidium to ionize and trap.
