Zusammenfassung:	The CEPXS/ONELD code package proved to be significantly more efficient than electron Monte Carlo for computing spherical Compton diode response to gamma irradiation. The authors review the mechanism responsible for the production of electric currents in Compton diodes, describe the calculation method, and present results for a few representative Compton diodes. The adjoint capability of CEPXS/ONELD allows the complete energy-angle response of a Compton diode to be determined with a single transport calculation. The calculated results compare well with measurement for energies between 0.5 MeV and 4.4 MeV. Because the calculations are so fast, many potential Compton diode designs with different dimensions and materials can be modeled, and the best design chosen for production.< >
