Improving pulsed DNP with optimal control

The numerical simulations resulted in an optimized DNP pulse sequence that gives an enhancement factor of 241 at an electron nutation frequency of 20 MHz. This poster provides insight into the experimental challenges.#GlobalnmrTC2023 pic.twitter.com/4iahRnqv2n

We use quantum optimal control algorithm to improve XiX DNP. The optimized DNP sequences with initial pulse lengths of 12 and 20 ns gave enhancements 2.4 and 1.6 times greater than XiX DNP, respectively. The challenges and anomaly between the numerical simulations and experiments will be addressed in the poster.
