Imaging of CsI(Tl) crystal event and double-slit Young’s interference by a single photon sensitive camera

We will discuss an imaging measurement with a single photon sensitive and low-noise camera aiming at a new paradigm in the optical readout of scintillation detectors. The features of the single photon sensitive camera will be characterized and demonstrated with a measurement of double-slit Young’s i...

Description
Summary:We will discuss an imaging measurement with a single photon sensitive and low-noise camera aiming at a new paradigm in the optical readout of scintillation detectors. The features of the single photon sensitive camera will be characterized and demonstrated with a measurement of double-slit Young’s interference in single photon mode. An imaging test on CsI(Tl) crystal and alpha source will be performed further for preliminary measurements on the noise level and sensitivity of the system with a 1/2″, f/1.4 lens, which reaches a sensitivity on light intensity around 1/10 of the 3-inch PMT and shows a potential to realize imaging of single alpha event. An application proposal for scintillation detectors will be further discussed, where it is usually assumed that imaging is not possible in such a photon-starved and large-emittance regime.
