Re: [time-nuts] 88Sr+ ion-clock live stream

In Cs my understanding is that a transition mF=0 to mF=0 transition is used - so it is insensitive to the magnetic field[1]. There is no magnetic field insensitive component of the 88Sr+ clock transition (other optical clocks will vary!) See e.g. around page 10 here for an energy-level diagram: htt

Finally received my replacement batteries and a suitable wall-wart. After installing the batteries and initialization as per the instructions posted to the list, it started working correctly with the original receiver. Thanks to all who helped. F.W.Bray > On Nov 26, 2019, at 2:04 PM, Frederick

Re: [time-nuts] 88Sr+ ion-clock live stream

Hello to the group. This is great to watch and see the development of an exotic clock. I guess I need a bit of help in understanding what I am seeing. To a point I understand Zeeman images in respect to a cesium reference at least. But in that case there is a single higher peak thats the correct on

Re: [time-nuts] 88Sr+ ion-clock live stream

Hi Jim, yes you are right the background is a camera-image (about 30x magnification, maybe 1um per pixel). We use a microscope-objective, a narrow 422nm bandpass filter, then an image-intensifier, and a fairly standard CCD camera that looks at the output of the intensifier. When everything is work
