Superconducting nanowire single-photon detectors (SNSPDs) are a promising new ultra-sensitive and low-noise detectors for applications ranging from deep-space exploration to ultrafast space-based optical quantum communication networks. Their susceptibility to damage from the high-radiation environments found in space is not yet understood. Professor Berggren and his team will investigate radiation damage to SNSPDs in their lab by bombarding them 30keV helium ions at irradiated doses far exceeding the expected levels in space. Using the results of these experiments and complementary modeling efforts the team will also investigate mitigation strategies.
