Standardisation of the data format for list-mode digital data acquisition: Survey results

Tue, 2016-04-26

Abstract

In the frame of Commission Mandate M/487 'Security standards', CEN/TC 391 assigned the highest priority to the standardisation of list-mode data, together with three other standardisation proposals. In response, the JRC ERNCIP Thematic Group on Radiological and Nuclear Threats to Critical Infrastructure described the state-of-the-art on list-mode data acquisition and proposed the basic elements of a standard data format. In addition, the RN Thematic Group conducted a survey addressed to users of digital data acquisition for nuclear instrumentation to investigate their needs with respect to the standardisation of the data format. This report presents the results of the survey, which will serve as an important input for the development of a preliminary draft standard that will accompany a New Work Item Proposal for a new international standard, to be submitted to the IEC in the frame of the EMPIR Project 14SIP07 'DigitalStandard', which will continue on the work initiated by the ERNCIP RN Thematic Group.

Critical parameters and performance tests for the evaluation of digital data acquisition hardware

Wed, 2015-01-14

Abstract

Recent developments of digital data acquisition systems allow real-time pre-processing of detector signals at a high count rate. These so-called pulse processing digitizers are powerful and versatile instruments offering techniques which are important for nuclear security, critical infrastructure protection, nuclear physics and radiation metrology. Certain aspects of digital data acquisition affect the performance of the total system in a critical way and therefore require special attention. This report presents a short introduction to digital data acquisition, followed by a discussion of the critical parameters which affect the performance in the lab and in the field. For some of the parameters, tests are proposed to assess the performance of digital data acquisition systems. Good practices are offered to guide the selection and evaluation of digital data acquisition systems. More general performance criteria which are not specifically related to digital data acquisition systems are discussed separately.

List-mode data acquisition based on digital electronics - State-of-the-art report

Fri, 2014-12-05

Abstract

This report deals with digital radiation detection systems employing list-mode data collection, which improves data analysis capabilities. Future data acquisition systems shall also ultimately enable the movement of detection data from first responders electronically to analysis centres rather than the costly and time consuming process of moving experts and/or samples. This new technology is especially useful in crisis events, when time and resources are sparse and increased analysis capacity is required. In order to utilise the opportunities opened by these new technologies, the systems have to be interoperable, so that the data from each type of detector can easily be analysed by different analysis centres. Successful interoperability of the systems requires that European and/or international standards are devised for the digitised data format. The basis of such a format is a list of registered events detailing an estimate of the energy of the detected radiation, along with an accurate time-stamp for recorded events (and optionally other parameters describing each event).
