Overview on Low-flux Detectors

Understand

Laboratory based searches for weakly-interacting slim particles (WISPs) of the light-shining-through-a-wall type (LSW) use visible or near-infrared (NIR) laser light.

• Low-noise and highly efficient detectors are necessary to improve over previous experiments.
• These requirements overlap with the requirements for single-photon detectors (SPDs) for quantum information (QI) experiments.
• In this contribution, the sensitivity of several QI SPDs is compared to photo-multiplier tubes (PMTs) and imaging charge-coupled devices (CCDs).
