Einstein-Elevator — •Alexander Heidt — HITec, Hannover, Niedersachsen

More and more people are striving to explore space and to colonize it as well as to use its advantages for basic research in physics. To be able to accomplish this, technologies are necessary that operate in special gravity conditions. With the motivation to develop and investigate such technologies, the Einstein-Elevator was built, which, in addition to simulating weightlessness, is able to simulate other gravity conditions. The advantages of the Einstein-Elevator are the high repetition rate of up to one hundred flights per day in combination with a weight of the payload of up to 1,000 kg for the experiment setup, which can have a diameter of up to 1.70 m and a height of 2 m. The duration of the gravity condition is four seconds and these can be adjusted between Lunar and Martian gravity down to microgravity. Currently, several projects are underway in various research fields, including the core research areas mechanical engineering and fundamental physics: In the area of fundamental physics research based on atom interferometry is carried out. Projects currently in progress include INTENTAS to measure the entanglement of atoms in microgravity with a compact sensor, with special requirements for stabilizing a magnetic field, and DESIRE to measure dark energy, where the motion, especially the rotation, of the Einstein elevator must be stabilized. In addition, the team is continuously developing the facility, opening up gravitational conditions that could not previously be simulated on Earth.
