Periodic Report Summary 1 - NEUTANDALUS (NeutAndalus: boosting interdisciplinary neutron science in Spain and Europe)

The objectives of the project are:

1. Perform at least two start-of-the-art experiments in the most powerful neutron beam facilities of Europe.

2. Design, build and exploit a neutron beam facility using the existing accelerators of University of Seville and the associated National
Centre of Accelerators CNA.

3. Create an interdisciplinary research team for the design and construction of a versatile laser-driven neutron beam facility.

The project is quite well advanced regarding the tasks included in Objective 1. The envisaged prompt fission g-ray (PFG) experiments were already carried out at the Budapest Research Reactor and the first results, corresponding the PFG from 241Pu have been already published. The study of correlations between PFG and the fission fragments so that the results from 241Pu can be extrapolated to other isotopes, is ongoing. Regarding the set of experiment at CERN for nuclear astrophysics, the radioactive targets were successfully prepared at ILL and PSI between 2013 and 2015 and the experiments have been already carried out at CERN, with preliminary results that are very interesting. In addition, experiments on 147Pm and 171Tm are planned along 2016 at LiLiT in Israel in the framework of a new collaboration. All these are first ever measurements and will have an impact on current stellar nucleosynthesis calculations in several stellar scenarios.

All the activities related to the neutron beam at CNA, a collaboration has been established between al the Spanish institutions with an interest in the set-up and exploitation of the neutron beam line at CNA. Two meetings have been held at Sevilla and simulations are ongoing. A first test beam experiment with continuous beam will take place in spring 2016, and then the bunching system will be installed in summer. The first tests for time-of-flight measurements will take in 2017.

Last, the tasks within Objective 3 have just started in 2015. A detailed study of the experiments for neutron production with lasers has been useful for identifying the potential collaborators. A first contact with CLPU has already taken place and with ASTERIX is envisaged in 2016. The corresponding simulation studies show very encouraging results; if we succeed on producing and using a laser-based neutron beam, this could have a great impact in the neutron beam users community thanks to the reduction in size and cost of future facilities.

The development of this scientific program has had a very positive effect in the career development of the fellow, supported both by the Spanish MINECO and Universidad de Sevilla. The MINECO granted the fellow initially with a 3 years Juan de la Cierva contract and then with one of the few Ramón y Cajal 5 years contract, the step previous to a permanent position. In addition, MINECO and U. Sevilla have granted funds for a total of 129.000€ and 82.000€ (a PhD student 4 years´ salary) to the host research group for complementing this Marie Curie project. With this means, the prospect for the useful completion of the NeutAndalus project are very encouraging.
