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.

In 1968, following the success of his role in "Mary Poppins" four years earlier, Dick Van Dyke was asked by the producer of the 007 films, Alfred R. Broccoli, to take over the 007 role from Sean Connery.
Incredulous, Van Dyke responded: “Have you heard my British accent?”
This year, the Mastodon team returned to FOSDEM for the third time.
FOSDEM is an annual gathering of open source developers, held in Brussels.
We’re excited to report that the Fediverse is feeling vibrant!
FOSDEM has become a central element of EU Open Source Week
- a series of events, meetups and workshops that have formed around the conference itself.
The range of events makes this trip to Brussels valuable for our team,
with opportunities to meet other …
This week: Scatec locked in a 25-year deal for Africa's largest solar-plus-storage project in Egypt. Vattenfall greenlighted Germany's largest 1.6 GW offshore wind cluster. Brooklyn is building a 9.46 MWh battery-backed EV charging depot.
Real progress, happening now.
