The DC accelleration voltages available to the real-world experimenter will not allow even close to relativistic energies for protons and deuterons. The charge to mass ratio is too low. Also, cross-sections for the common reactions tend to fall off beyond an Mev or so. As others have pointed out, lower voltages and higher currents have a larger chance of payoff, hence the interest in pulsed systems.
