An arrangement for detecting neutrons. In an aspect, the arrangement includes a first neutron detector including a neutron-sensitive substance, and the first neutron detector having an associated gain performance. The arrangement includes a second neutron detector including neutron-sensitive substance, and the second neutron detector having an associated gain performance. The gain performance of the second neutron detector matching the gain performance of the first neutron detector. In an aspect, the arrangement includes a first neutron detector including at least some helium. The arrangement includes a second neutron detector including at least some helium and at least some Boron-10.

Method for gain matching neutron detectors containing various He&#x2014;3 partial pressures

A detector arrangement for detecting at least one of rays, ions and particles includes a plurality of detectors. Each detector has a respective anode output and the detectors are arranged with the respective anode outputs being in an electrical series. The arrangement includes a plurality of resistive elements interspersed in the electrical series. The arrangement includes a first measurement point at a first end of the electrical series and a second measurement point at a second end of the electrical series. The arrangement includes electrical circuitry, electrically connected to the first and second measurement points for receiving electrical signals/pulses from the first and second measurement points, and for using the electrical signals/pulses from the first and second measurement points to determine which of the plurality of detectors made the detection utilizing a division of charge that exists between the first and second measurement points.

An arrangement for detecting neutrons. A first neutron detector includes at least some helium, and may include some Helium-3. The first neutron detector has an associated gain performance. A second neutron detector includes at least some helium. The second neutron detector may include some Helium-3 and may include some Helium-4. The second neutron detector has an associated gain performance. In an aspect, the gain performance of the second neutron detector matches the gain performance of the first neutron detector. In an aspect, the amount of all helium of the second detector is the same as the amount of all helium in the first detector. In an aspect, at least one of the first and second detectors includes at least some additional, different neutron-sensitive substance. In an aspect, at least one of the first and second detectors includes some Boron-10 as the additional, different neutron-sensitive substance.
