Abstract: A magnetic photomultiplier tube (PMT) system, including a PMT. The PMT including a photocathode for converting an impinging photon to a photoelectron, an anode, and at least two or a series of oppositely facing pairs of dynodes, wherein each pair is spaced apart from an adjacent pair, a first electric field being generated intermediate at least one pair of oppositely facing dynodes and a second electric field generated intermediate at least one adjacent pairs of dynodes. The PMT system includes a magnetic field generated by a magnetic system, the PMT being positioned within the magnetic field.

Abstract: An in-vacuum light sensor system, including a light sensor assembly comprising a photocathode configured for converting an impinging photon to a photoelectron, a semiconductor diode configured for multiplying the photoelectron impinging thereon, and a housing including vacuum-compatible materials configured for being placed in a vacuum chamber. The housing is configured for housing the photocathode and the semiconductor diode and for propagation of the photoelectron from the photocathode to the semiconductor diode. An electrical biasing subassembly is configured for electrically biasing at least the photocathode and the semiconductor diode, and the vacuum chamber is configured for positioning the light sensor apparatus therein.
