Neutron Detectors
Mechanisms for detecting neutrons in matter are based on indirect methods. Neutrons, as their name suggests, are neutral. Also, they do not interact directly with the electrons in matter, as gamma ray$ do. The process of neutron detection begins when neutrons, interacting with various nuclei, initiate the release of one or more charged particles. The electrical signrdsproduced by the charged pa...
متن کاملSuperconducting Magnets for Detectors
A Fermilab/KEK/University of Tskuba, Japan collaboration is designing a large superconducting solenoid for the Fermilab Collider Detector Facility (CDF). A review of the status of other superconducting solenoids built for colliding beams machines is presented and progress on the design of the CDF magnet is discussed. Two types of superconducting coils appear to be feasible; a bath-cooled cryost...
متن کاملSuperconducting Microresonator Detectors
Figure 1: Left: Principle of operation of superconducting microresonator detectors, following[1]. The absorbed photon energy breaks Cooper electron pairs in a thin superconducting film (a) which is part of a lithographed microresonator circuit (b). The breaking of Cooper pairs causes a change in the surface reactance and resistance of the film, leading to a shift in the resonance frequency fr a...
متن کاملSilicon Carbide Neutron Detectors
The potential of Silicon Carbide (SiC) for use in semiconductor nuclear radiation detectors has been long recognized. In fact, the first SiC neutron detector was demonstrated more than fifty years ago (Babcock, et al., 1957; Babcock & Chang, 1963). This detector was shown to be operational in limited testing at temperatures up to 700 oC. Unfortunately, further development was limited by the poo...
متن کاملMicrostructured semiconductor neutron detectors
Perforated semiconductor neutron detectors are compact diode detectors that operate at low power and can be fashioned to have high thermal neutron detection efficiency. Fabricated from high-purity Si wafers, the perforations are etched into the diode surface with ICP-RIE and backfilled with LiF neutron reactive material. The intrinsic thermal neutron detection efficiency depends upon many facto...
