Statement on the Hamas Attack on Israel

The ChETEC-INFRA community strongly denounces the heinous, terrorist assault that was launched against Israel on October 7, 2023. The scientific community in the field of nuclear astrophysics in Europe expresses its solidarity with the Israeli people, particularly the scientists and their families who have been impacted, and especially to our ChETEC-INFRA partners at the Hebrew University in Jerusalem. Terror goes against the core values of ChETEC-INFRA and of the scientists in its community. We oppose violence against civilians regardless of nationality and hope that peace in the region can be reestablished. As scientists we believe that political differences should be resolved peacefully.

Transnational Access to 13 Facilities: Proposals Collected until February 17, 2024

The Transnational Access program of ChETEC-INFRA supports access to 13 European infrastructures for nuclear astrophysics studies. Facilities include observatories, ion-beam accelerator laboratories, and a high-performance computing cluster.

Access can be provided in different ways. While some facilities mainly offer access in visitor mode (users traveling to the facility to conduct their project with financial support available for their travel), and others focus on service mode access (work on site at the facility performed by local staff in coordination with the users), a number of facilities are available to offer access in ways most suitable for the science case at hand. Facility access is provided free of charge to the user, and awarded based solely on scientific merit of the proposal. Scientists with affiliations from any other country than the country of the facility are eligible to submit proposals.

The next collection date for proposals is February 17, 2024. The following call will be open until May 2024.

General information on Transnational Access, contact information and the link for the weekly open “office hours” on Zoom can be found on this page.

Update of NetGen Now Online

The nuclear NETwork GENerator NetGen is an interactive, web-based tool to help astrophysicists in building up a nuclear reaction network as defined by each user. It generates tables of the necessary nuclear reaction rates on a temperature grid specified by the user, and provides the references of the sources of these rates. All reaction rates, theoretical or experiment-based, include the contribution of thermally populated excited target states through the calculation of the stellar enhancement factor. NetGen includes about 8330 nuclides located between the neutron and proton driplines in the 1 ≤ Z ≤ 110 range.

In the latest version, NetGen include 90 new experimental reaction rates and the possibility to use the ASTRAL database for neutron-capture reactions.  alpha-decay, beta-decay and spontaneous fission rates have been updated with Nubase2020 (Kondev et al. 2021). The mass models have been updated to the experimental + recommended masses from the atomic mass evaluation AME’20 (Huang et al. 2021).

Finally, the website has been redesigned and additional functionalities have been added: possibility to plot individual rates, explore all the references available in NetGen for individual rates, interactive reaction choices, and other parameters.

Call for Transnational Access Proposals: Visitor and Service Mode at Facilities

ChETEC-INFRA’s Transnational Access program offers access to 13 facilities in the field of nuclear astrophysics, spanning from accelerator laboratories for accelerator mass spectrometry (at DREAMS and VERA), accelerator facilities for ion beam experiments (Felsenkeller Accelerator Laboratory, Tandem Accelerator at the University of Cologne, Cyclotron at Atomki, van-de-Graaff accelerator at the University of Frankfurt, Tandetron accelerator at IFIN-HH, and the PTB Ion Accelerator Facility), a high-performance computing cluster (Viper) and optical telescopes (Nordic Optical Telescope, Rozhen National Astronomical Observatory, Perek 2-m Telescope at the Ondřejov observatory, Molėtai Astronomical Observatory).

While some facilities mainly offer access in visitor mode (users traveling to the facility to conduct their research, with financial support available for their travel), and others focus on service mode access (work on site at the facility performed by local staff in coordination with the users), various facilities are available to offer access in ways most suitable for the science case at hand.

As an example we would like to emphasize the case of the Nordic Optical Telescope (NOT), which apart from regular visitor mode also offers (queue) service mode observing and provides a wide range of options for flexible scheduling through Target-of-Opportunity programs and/or monitoring programs on any time-scale (from hours to years).

Transnational Access proposals in ChETEC-INFRA are collected every three months. The current call for proposals is open until November 17, 2023.

Interested in which facility and mode of access may be most suitable for your nuclear astrophysics science case? Please do not hesitate to reach out to the contacts at the individual facilities or to the ChETEC-INFRA TA Management team via e-mail or through the weekly office hours.

High School Students Visit Camp on Astrophysics at TU Dresden

24 students from schools of the national Excellence School Network MINT-EC conducted research on astrophysics at the TUD Dresden University of Technology from October 23 to 26, 2023. For four days, they worked together with scientists from the Institute for Nuclear and Particle Physics of TU Dresden and from the DeltaX School Lab at the Helmholtz Center Dresden-Rossendorf (HZDR) on the physics of stars. During the camp, participants experienced how new scientific insights into the origin and development of the fascinating celestial bodies made of gas and plasma are gained in the laboratory or at the telescope.

The participants of the camp visited the Dresden underground laboratory “Felsenkeller” and learned how accelerators are used to investigate what happens inside stars. In the ChETEC-INFRA Masterclass on Astrophysics, led by Hannes Nitsche, a PhD students from TUD, they were introduced to nuclear reactions, their connection with the evolution of stars and the formation and abundance of chemical elements. By using a Stellar Analysis Pipeline tool called webSME, students analyzed spectra from stars, determined stellar parameter and measured elemental abundances.

The participants of the Camp on Astrophysics were selected from 120 applications from all over the world. They traveled from far away for the camp and took many hours of train ride. Two young people from the German School Istanbul came to Dresden accompanied by their teacher to participate in the astrophysics camp. There was also a student from the German International School Washington, who is very interested in astrophysics and therefore chose this camp out of the many exciting camps all over Germany.
