The goal of this project is the development of new shaped pulses and pulse sequences based on optimal control theory to improve the performance of EPR experiments. Composite and shaped pulses are basic building blocks in state of the art NMR experiments and recent technological advances have made it possible to shape EPR pulses on the nanosecond timescale. With the help of optimal control methods, the physical limits of pulse sequence performance can be explored and practical sequences can be developed that approach these limits with the required tolerance to experimental imperfections. We will develop optimized amplitude- and phase-modulated pulses that take spin-spin couplings, relaxation and experimental limitations of typical EPR settings into account. In addition to the design of optimal individual pulses, we will develop so-called cooperative pulses for experiments such as PELDOR, DQC, HYSCORE and DNP. An additional focus will be the development of hyperfine decoupling sequences. Furthermore, we will develop tools for the analysis of complex pulse shapes to provide a better understanding of the underlying mode of action.
