A review is presented on the use of Lagally's Theorem to determine forces and moments on bodies moving through an ideal fluid, including the extension to unsteady flows by Cummins and the evaluation of the virtual moment by Landweber and Yih for the case of sources and doublets. The latter is generalized to cover any type of singularity. Applications thus far have been restricted to distributions of singularities which lie entirely within the body. This paper considers the lifting body problem in which a vortex or doublet sheet cuts through the body. It is shown that direct application of the final Lagally equations to such a problem yields erroneous results. An approach is presented in which the Lagally integrals are correctly evaluated for this type of singularity distribution.

We report on 2 recent developments in an ongoing program of characterizing and improving the National Electrostatics Corp. (NEC) MC-SNICS ion source at University of California (UC) Irvine's Keck AMS laboratory. First, we have investigated the possibility of modifying a large-body (134-sample) MC-SNICS to incorporate the UC Irvine Cs oven and vacuum-insulated Cs feed tube, which provide better confinement of Cs than the standard NEC setup. In our 40-sample source, the feed tube enters the source housing directly below the ionizer assembly. This area cannot be accessed for machining on the 134-sample source, but we have successfully tested a modified geometry where the delivery tube enters the body via the source end flange. Second, we recently installed a second beam profile monitor in the injection line of our spectrometer to allow us to make online emittance measurements. At full output (150 μA of C− at 55 keV), the emittance of our source at 8 kV sputtering voltage is approximately 40π mm mrad.
