Abstract: Nuclear security operations and forensic investigations require the utilization of a suite of instruments ranging from passive gamma spectrometers to high-precision laboratory sample analyzers. Gamma spectroscopy survey is further broken down into wide-area search performed with large-volume scintillator-based mobile survey spectrometers which are integrated with geographic position sensors for mapping and identification of hot zones, and high-precision long-dwell measurements using solid state spectrometers for follow-on characterization to establish isotopic content and ratios. While performing well at detecting the presence, quantity and type of radioactivity, all of these methods have limited ability to determine the location of a source of radioactivity. In recent years, technology advances have resulted in gamma imager devices which can create an image of the distribution of radioactive sources using the gamma emissions which accompany radioactive decay, and overlay this on an optical photograph of the environment. These gamma imaging devices have arisen out of methods developed for medical physics, experimental particle physics, and astrophysics, resulting in a proliferation of different technological approaches. Those responsible for establishing a nuclear security concept of operations, require guidance to choose the proper gamma imager for each of the application spaces in a tiered response. Here the results of an intercomparison of two gamma imagers based on two widely different technologies, semiconductor and scintillator detectors, are presented. The optimal utilization of these imaging technologies in a tiered response is discussed based on the results of the trial. Finally, an outlook on future directions for gamma imaging advances is provided.

For those of you curious - the Nazis downtown are getting absolutely humiliated.
The big anti-Islam protest downtown currently consists of about 8 protesters and hundreds, maybe thousands, of counter protesters. The counter protesters are currently walking/pushing the protesters off of City Hall grounds. True Minnesota hospitality at its best.
Jake Lang [right-winger who organized the event] and a handful of other racists/RW propagandists are surrounded by about 50 cameras and some antifascists chanting him down. A banner the group arrived with has been broken.
Currently has only about 5 supporters, and is being drowned out by counter protesters
The group led by Jake Lang tried to get inside Minneapolis City Hall, but the building is closed, as it is every Saturday.

US voters linking climate crisis to rising bills despite #Trump’s ‘green scam’ claims:
“It’s a fundamental error to treat these issues as mutually exclusive – climate solutions are also cost-of-living solutions. Most of the elite discourse is very bad at estimating or understanding levels of public concern, and this is a good example of this.”

So I busted out an old laptop and installed headless ubuntu minimal (I like to start small) so that I can start setting up some autonomous agents. My first step was to install Claude Code so that it could setup everything else for me, but after a few hours at it, both Claude and I admit that Claude Code is broken on a headless install. We tried a bunch a different way to get it to take a damn key, but the installer insists on an OAUTH auth that requires a browser.

Abstract: Magnetometry based on diamond nitrogen-vacancy (NV) centers has been extensively studied for applications requiring diverse capabilities, spanning from nanometer spatial resolution to subpicotesla sensitivity. Among various applications, diamond magnetometers can demonstrate high sensitivity magnetic sensing within millimeter-scale size for endoscopic applications. However, the trade-off between sensitivity and spatial resolution of diamond magnetometry makes it difficult to achieve such a probe. In this study, we present a millimeter-scale rigid diamond magnetometer probe with enhanced sensitivity via optimizing the optical design. By coupling the frustum diamond with the miniaturized compound parabolic concentrator (CPC) lens, we enhance the fluorescence collection efficiency by 37% within 4 mm diameter, and the achieved sensitivity is 200 pT/Hz1/2 based on the sample with the resonance linewidth of ~8 MHz. With this verified structure, endoscopes with mm-size probe and picotesla sensitivity can be projected for surgical and industrial applications in the future.
