Abstract
In the frame of the European Commission funded integrated project CHANDA (solving CHAllenges in Nuclear DAta) the importance of nuclear target preparation for the accurateness and reliability of experimental nuclear data is set in a dedicated work package (WP3). The global aim of WP3 is the development of a network for nuclear target preparation and characterization, enabling to coordinate the target production corresponding to the experimental requirements. Therefore, a set of tasks within the work package needs to be followed. Primarily, an inventory of target related facilities and radioisotope providers was created. In the next step a priority list of target requests was made in agreement with the target user considering the technical specification, the scheduled experiments and the availability of the target laboratories. A set of target requests has been assigned to the Target Preparation laboratory of the European Commission – Joint Research Centre – Directorate G (EC-JRC.G.2) in Geel, Belgium. This contribution gives an overview of the nuclear targets that are produced within the CHANDA project. The equipment and techniques available for the preparation and characterization of uranium, plutonium and neptunium layers with an areal density ranging from 60 to 205 μg cm−2 will be emphasized.
Highlights
Experiments with the aim to improve the quality of nuclear data require samples used as “targets”
In order to have high quality tailor made targets available for the nuclear data measurements within the above mentioned constraint, it is beneficial to share the existing know-how and expensive equipment and to focus on the complementarities of still existing target production facilities. This need has been described in the work package WP3 of the project of solving CHAllenges in Nuclear Data (CHANDA) [1]
Actinide target requests within CHANDA The target requests for uranium, plutonium and neptunium layers listed in Table 1 were discussed with the spokesperson and target user of the experiments approved in the CHANDA Program Advisory Committee (PAC) meeting
Summary
Experiments with the aim to improve the quality of nuclear data require samples used as “targets”. In order to have high quality tailor made targets available for the nuclear data measurements within the above mentioned constraint, it is beneficial to share the existing know-how and expensive equipment and to focus on the complementarities of still existing target production facilities. This need has been described in the work package WP3 of the project of solving CHAllenges in Nuclear Data (CHANDA) [1]. The aim of WP3 is to create a network of laboratories for the preparation and characterization of samples and targets for nuclear data experiments and to improve the communication channels between target users and producers in the EU and world-wide. The preparation and characterization of uranium, plutonium and neptunium layers with an areal density ranging from 60 to 205 μg cm−2 was assigned to the EC-JRC.G.2 in Geel, Belgium [6]
