I will address the design of pulsed experiments in magnetic resonance with focus on pulsed dynamic nuclear polarization (DNP) for sensitivity enhanced NMR and quantum sensing. Focus will be efficient control of linear and bilinear fields in effective Hamiltonians to enable design of broadband DNP experiments by non-linear optimization and optimal control. The talk will cover basic theory, numerical optimization, and experimental data with DNP pulse sequences presenting 100 MHz electron-spin bandwidth.
