New court filings allege that federal and state officials withheld evidence of the Trump administration’s involvement in the Everglades detention facility known as “Alligator Alcatraz,” a revelation that could revive a court-ordered shutdown. The Jan. 7 filings come as the Miccosukee Tribe presses ahead with its legal challenge amid President Donald Trump’s recent veto of legislation expanding the tribe’s control over Everglades lands.
The filings, submitted by Friends of the Everglades…

Proton Energy Dependence of Radiation Induced Low Gain Avalanche Detector Degradation

Abstract: Low Gain Avalanche Detectors (LGADs) are key components for precise timing measurements in high-energy physics experiments, including the High Luminosity upgrades of the current LHC detectors. Their performance is, however, limited by radiation induced degradation of the gain layer, primarily driven by acceptor removal. This study presents a systematic comparison of how the degradation evolves with different incident proton energies, using LGADs from Hamamatsu Photonics (HPK) and The Institute of Microelectronics of Barcelona (IMB-CNM) irradiated with 18 MeV, 24 MeV, 400 MeV and 23 GeV protons and fluences up to 2.5x10^15 p/cm2. Electrical characterization is used to extract the acceptor removal coefficients for different proton energies, whereas IR TCT measurements offer complementary insight into the gain evolution in LGADs after irradiation. Across all devices, lower energy protons induce stronger gain layer degradation, confirming expectations. However, 400 MeV protons consistently appear less damaging than both lower and higher energy protons, an unexpected deviation from a monotonic energy trend. Conversion of proton fluences to 1 MeV neutron-equivalent fluences reduces but does not eliminate these differences, indicating that the standard Non-Ionizing Energy Loss (NIEL) scaling does not fully account for the underlying defect formation mechanisms at different energies and requires revision when considering irradiation fields that contain a broader spectrum of particle types and energies.

Caught a bug over the holidays so I’m mostly resting, feeling sorry for myself, and taking the time to at least carry out some mindless housekeeping tasks (updating dependencies, etc.) on some of my Node modules.
Released updates to the following packages yesterday:

Nachdem wir mit dem Assistenzhund 🐕🦺meiner Frau schon am Schweizer Nationalfeiertag nach Deutschland geflüchtet waren, brauchten wir eine Lösung für Silvester.
Flughafenhotels to the rescue: Die schallisolierten Hyatt und Radisson Blu am Flughafen Zürich waren diese Nacht voll mit Hunden und ihren Familien, und es war kein Knall zu hören. Ruhiger Schlaf.
Tut euren vierbeinigen besten Freunden diesen Gefallen doch nächstes Jahr auch!

Can you do a favor for my friend @…? He was already having a lousy enough week with his car and his city falling apart when state troopers arrested his wife @… for protesting against the murder of Alex Pretti. (Arrested for what? AFAICT, they were just looking to make an example of some protestors. Just good old harassment via the legal system.)
Now the family has lost work and impending legal bills on top of that new transmission. I’m sure they’d appreciate it if you can chip in a few bucks:

SpaceX filed a request with the FCC on Friday seeking approval to put a constellation of 1 million data centersatellites into orbit.
While the FCC is unlikely to approve a network that expansive, SpaceX’s strategy has been to request approval for unrealistically large numbers of satellites as a starting point for negotiations.
