This circuit is presented as an alternative to the IR beam break detector featured in the June 2009 issue (Silicon Chip). In order to make it relatively insensitive to ambient light, it uses a ...

The beam is off, but high energy physics research is very much on at one of the world’s premier particle physics labs. The requirements of social distancing have prompted scientists at the U.S.

Scientists working on the Short-Baseline Near Detector (SBND) at Fermi National Accelerator Laboratory have identified the detector’s first neutrino interactions. The detector has been been planned, ...
