Radiation measurement using timing-over-ethernet protocol

摘要

A highly scalable platform for radiation measurement data collection with high precision time stamping and time measurements between the elements in the detection array uses IEEE 1588 with or without Synchronous Ethernet (timing over Ethernet) to synchronize the measurements. At a minimum, the system includes at least two radiation detector units, an IEEE 1588 and SyncE enabled Ethernet switch, and a computer for processing. The addition of timing over Ethernet and power over Ethernet (PoE) allows a radiation measurement system to operate with a single Ethernet cable, simplifying deployment of detectors using standardized technology with a multitude of configuration possibilities. This eliminates the need for an additional hardware for the timing measurements which simplifies the detection system, reduces the cost of the deployment, reduces the power consumption of the detection system and reduces the overall size of the system.

1. A radiation detector comprising:
at least two radiation detecting nodes, wherein first and second ones of the at least two radiation detecting nodes are arranged such that the first node is configured to detect scattering events and the second node is configured to detect absorption events related to the scattering events; a system server configured to communicate via Ethernet with said nodes to detect signals associated with radiation detection events; and, a clock system synchronizing said radiation detecting nodes according to IEEE 1588 protocol, wherein:
one of the at least two radiation detecting nodes is configured to provide a synchronization signal including a clock frequency and a clock phase to others of the at least two radiation detecting nodes over the Ethernet,each radiation detecting node is configured to provide a time stamped event package to the system server in response to detecting a radiation event, andthe time stamped event package comprises spectroscopy information and pulse shape information of the radiation event and a time stamp derived from the synchronization signal provided by the one radiation detecting node.
