Abstract: A neutron detector includes a bulk of a neutron moderating material, a first housing consisting of or comprising a gamma ray attenuating material, a second housing consisting of or comprising a gamma ray attenuating material, a first sensor device comprising a gadolinium cover disposed in the first housing, and a second sensor device disposed in the second housing. The first sensor device and the second sensor device are each sensitive to gamma rays. The first housing and the second housing are arranged adjacent to each other in the bulk.

Abstract: A sending computer system generates a message and creates one or more security tokens to encrypt portions of the message. The computer system includes in the message a markup language identifier for the one or more security tokens used for encryption, and includes identification of the value type used to create the tokens. The computer system then serializes at least the portion of the message that identifies the one or more security tokens, without serializing other portions of the message that aid relaying of the message to a receiving computer system. A receiving computer system deserializes at least the portion of the message that identifies the one or more security tokens, and then uses deserialized token data to decrypt encrypted portions of the message. Each created security token can be made with customized data and fields, and can be made with a customized value type.
