Can a Penning trapped electron or ion be used as a time of flight gravimeter?

Subject: In your months long measurements on single electrons did you see diurnal variations? Has anyone tried to make a single electron gravimeter? Gerald, I was doing a quick review of linear and quadratic effects in paramagnetic resonance, and happened to notice “Gabrielse and company confined single electrons for months at a time”.  For many

About optically connected processors for home use and many things

Nora, Thanks, I will keep that in mind. If you cast tiny angular (square, triangular, for example) blocks of plastic on ends of an optical fiber, then polish the whole thing, that would give a fiber that would alighn properly with a corresponding hole and fiber (or fibers).  It is something that human hands could

Merging and upgrading sensor networks towards new industries and materials

Shawn, The atmospheric gravitational noise is much larger than the signals from the subsurface (usually). The noise in that gravimeter you want to buy is mostly atmospheric and thermal radiation field connected. Calibrate it against the sun and moon first. Then against 3D near realtime atmospheric models. (Climate and meteorology are just atmospheric, and the

Gravity and Temperature, gravity and pressure

Shawn, What I am saying is that the energy density of the radiation field of the earth, which you can map by mapping the temperature is just “gravitational field stuff”.  The magnetic field of the earth which you can convert to magnetic energy density is also made of “gravitational field stuff”. The gravitational field of

Gravitational, Magnetic and Electric Field Changes from Global Climate Change

I wrote yesterday about magnetism and gravity and temperature at gravimeter and related sensor array detector sites.  I give averages over all frequencies, but the fine details can be tracked across all frequencies from picoHertz to ZettaHertz. Relation between gravity, magnetism and temperature at the earths surface at /?p=1893 Today I realized that if global

Comment on Endaq Steve Hanly blog about accelerometer sensitivity

Accelerometer Specifications: Deciphering an Accelerometer’s Datasheet by Steve Hanly https://blog.endaq.com/accelerometer-specifications-decoding-a-datasheet I see you mention temperature sensitivity. I am writing an article on gravimeters and recommending different ones. Someone estimated their response to temperature. It can be estimated for gravimeter arrays. Here is how I estimated it. Relation between gravity, magnetism and temperature at the earths

Why the sun moon tidal signal is so important for helping global sensor arrays with calibration

Shawn, I worked with the US Agency for International Development, the US State Department, World Bank and many international organizations.  Most countries cannot afford to do their own mineral exploration, so outsiders come and take what they have. I helped put microcomputer training and technology into that system so that some countries could afford to

Relation between gravity, magnetism and temperature at the earths surface

I wrote this yesterday, and then realized that if global climate change increases the global temperature by 1 degree then that will change the readings at all accelerometer sites. But the (word that starts with i) at NASA and other places don’t give you the absolute temperature time series, only the change. But the impact

Comment on my video Windows USB GPS Device Based on UBlox Chip and UCenter Software

Windows USB GPS Device Based on UBlox Chip and UCenter Software https://www.youtube.com/watch?v=uJZHVKGrl6Y @Ali Zitouna Hamed, I am not sure what you mean by “base ntrip”. I made this long ago and have not used UBlox lately. Since then i have been working on software defined radios, electromagnetic interference, gravitational wave detection, imaging arrays for gravitational
