optics<\/a>.<\/p>\nAn additional improvement of the overall performance is being sought by the implementation of new technological approaches to preparing atomic ensembles. The payload is scheduled for launch in early 2026 and will directly replace the CAL apparatus in the ISS Destiny module.<\/p>\n
Why is this being launched on the ISS?<\/h3>\n The transport of the BECCAL payload to the ISS will offer the unique combination of weightlessness, accessibility, and a large number of experiments. This means that scientists will be able to carry out high-precision experiments, such as testing Einstein\u2019s equivalence principle, and developing quantum technology.<\/p>\n
“Ideally, the experiments require the ultracold atom cloud to be completely free of any forces. Weightlessness permits such conditions,” said Dr Andr\u00e9 Wenzlawski from the Windpassinger group at Mainz University.<\/p>\n
What experiments will BECCAL make possible?<\/h3>\n In the subproject, which has been funded with \u20ac3.4m, the collaborative team will work together to develop and realise a Zerodur-based optical splitting and switching system and implement it into the BECCAL payload.<\/p>\n
These developments will draw on the findings of numerous previous experiments conducted in microgravity conditions, such as MAIUS, QUANTUS, and KALEXUS, in all of which JGU participated in.<\/p>\n
“These experiments have allowed us to lay the technological foundations for running such an extremely complex experiment as well as to perform initial fundamental tests on the feasibility of the envisaged experiments,” said Wenzlawski.<\/p>\n
The robust laser modules necessary for the experiment are being supplied by the Ferdinand-Braun-Institut (FBH), which is currently manufacturing 55 of the narrow-band laser sources. Additionally, Humboldt-Universit\u00e4t Zu Berlin is coordinating the integration of these laser modules along with the optical beam splitting and switching benches into a compact overall system.<\/p>\n
The project is being financed by the German Space Agency of the German Aerospace Center (DLR) with funding from the German Federal Ministry for Economic Affairs and Climate Action, following a resolution by the German Bundestag.<\/p>\n","protected":false},"excerpt":{"rendered":"
The Johannes Gutenberg University Mainz (JGU) will work collaboratively with several other universities to develop a laser system for the BECCAL experiment, to study ultracold atoms on board the International Space Station (ISS).
