The researchers at U.S. National Science Foundation and Cornell University, a NYSERNet member created a single-crystal alkali antimonide photocathode with performance up to ten instances better than traditional photocathodes. One application of the new photocathode technology is development of ultra-fast electron. Learn more here: https://bit.ly/39fEFR0 @nysernet @cornell @NSF_NSB
