The electric solar wind sail, or E-sail, is a propellantless interplanetary propulsion system concept. By deflecting solar wind particles off their original course, it can generate a propulsive effect with nothing more than an electric charge. The high-voltage charge is applied to one or multiple centrifugally deployed hair-thin tethers, around whi...

Earth’s radiation belts are extremely important for space weather because they can store and accelerate particles to relativistic energies, which can have a potential impact on satellite functionality, communications, and navigation systems. The FORESAIL consortium wants to measure these high-energy particle fluxes to understand the dynamics of the...

Since 2013 the Technical University of Munich works together with students on LEO satellite projects. With FIRST-MOVE the chair for astronautics launched the first cubesat. The development for MOVE-II started in 2014 with the students also joining the management team. 2018 and 2019 marked successful launches of MOVE-II and MOVE-IIb satellites. Curr...

Galactic cosmic rays and solar particle events during deep-space missions to the Moon, Mars and other destinations are critical health risks to humans. A precise characterisation of the radiation environment within a spacecraft is needed to protect the astronauts from the diverse effects of radiation exposure. This work presents the development of...

Classical novae are environments which can produce heavier elements up to mass A ∼ 40. These nuclides at the endpoint of nova nucleosynthesis consist of elements such as Ar, K, and Ca. There is an order of magnitude discrepancy with the predicted and theoretical abundances of these endpoint nuclides produced in a classical nova. The uncertainty in...

In classical novae simulations, the uncertainty in the reaction rate of K(p,) has been shown to affect the abundances of endpoint nuclides significantly. To better understand the reaction rate, we have done a spectroscopic study on Ca. The reaction Ca(d,t)Ca at a beam energy of 22 MeV was used to populate excited states of Ca. Tritons were momentum...

This thesis is a feasibility study of the resonant 33 Cl(p, γ) 34 Ar and 34m Cl(p, γ) 35 Ar proton capture reactions, for stellar energies occurring in novae, at the new storage ring CRYRING at GSI. These re- action rates would be measured by detecting the yields of 34,35 Ar fusion recoils exiting the CRYRING hydrogen gas jet target; thereby requir...
