arXiv:2606.10121v1 Announce Type: new Abstract: Recently developed 15 um, 20 um, 25 um and 30 um cell size Hamamatsu Silicon Photomultipliers (SiPMs) were irradiated with reactor neutrons at JSI (Ljubljana) up to 2*10^14 n/cm^2 (1 MeV equivalent). The parameters of new and irradiated SiPMs were studied using pulsed light illumination. The effects of the neutron radiation on breakdown voltage, signal amplitude, dark current and noise for these devices are shown and discussed.

Exclusive-GM may ditch LFP batteries for future EVs SAN FRANCISCO, June 10 : General Motors may scrap plans to use a lower-cost, iron-based battery chemistry that many automakers are using to cut electric-vehicle costs, GM's head of battery technology said. The Detroit automaker had said it planned to develop lithium-iron phosphate, or LFP, batteries for use in future EV models, and would begin making those batteries in late 2027 at a jointly owned plant in Tennessee. But GM battery chief...
