This is something I've been watching closely for several years and happy to see being used now mainstream. EM systems typically send a real-time resistance measurement in their sequence to surface, which is used to measure signal attenuation. The curious thing in our Quantum EM system is how pronounced this has been vs. our past EM technology. The measurement that comes back is near to or at the bit depth rather than at the MWD tool like gamma. You can see here in our DigiDrill PowerTool the gamma follows the resistance spike about 90 min later as the MWD gamma sensor passes through the same spot the bit did when the resistance changed (yellow box) - this is at about 60 deg in the well. I believe our unique sealed gap isolation and higher power output have a lot to do with this improved measurement. It's a great feature we can offer the geosteering team for formation correlation and I'm not sure any other systems have this type of clear picture real-time of resistance. #geosteering #drilling #MWD #EMMWD 

The EM system transmits current that must bridge the gap sub to complete the electrical circuit. In Oil-Based Mud (OBM) environments, the drilling string’s exterior and interior are electrically isolated by the insulating properties of the mud. This makes the bit—where the tool interacts with new formations—the most effective point for electrical contact. Our observations show that as we drill through different geological layers, the changes in EM resistance correlate closely with the resistivity logs, providing a clear mapping of formation boundaries.

#CMSPaper 1338 describes a precision measurement of the production rate of the quantum carriers of the weak force, the Z and W boson. These measurements allow comparison and improvement to detailed (next-to-next-to-next-to-leading order) quantum chromodynamics calculations for those particles, and help for precision understanding of the strong force in the standard model https://buff.ly/3ZaS4kI

Moving ... towards #darkmatter detection. The "First mechanical realization of a tunable dielectric haloscope for the MADMAX axion search experiment" is now available on arXiv:2407.10716 We tested the #piezoelectric #motor developed by JPE (https://lnkd.in/evRFTRrN) for the MADMAX experiment inside a strong magnetic field up to 1.6 T and at cryogenic temperatures down to 35K. The measurements of the velocity and positioning accuracy match the experimental requirements. It's time to move ... on to the next challenge. MAgnetized Disc and Mirror Axion eXperiment MADMAX

TL;DR version: On the *right* are the two Attochron Carrier-Grade FSO Comms™ light sources with a coherence length of approximately 100 µm. One of these will be in the ALTIS-7(TM) FSOC link going to market in 2025. By contrast a ‘CW’ laser (on the left) is the light source [laser] everyone else in the world attempts to use in their FSOC. With a coherence link of many *centimeters*, this picture shows that, after beaming 1 mile through air, only the Attochron lasers are not affected by the coherent interference scrambling the CW laser (the result of atmospheric turbulence/scintillation).

#CMSPaper 1323 looks for a high-mass undiscovered particle that decays to a photon and a W boson. These kinds of particles are, for example, predicted by theories that predict the unification of forces at much lower energies than the (Planck scale) energy where the unification of forces is normally expected. There are non-significant excesses around 2 TeV, but definitely no champagne yet, more data collected now will be used to confirm if there is something there https://buff.ly/3Yf6gsu
