If we are to do a workmanlike job of studying the strong interactions it is imperative that we have knowledge of the spin dependence of the forces. This implies that polarization experiments are essential. Already Bareyre, Bricman, Stirling and Villet have shown that pion-proton polarization experiments should be interpreted as indicating two new resonances not previously seen by other methods. The present-day approach to determining detailed pion-proton scattering amplitudes is to use measured differential cross sections, polarization measurements, dispersion relations, and isospin conservation rules. Further assumptions are unitarity of the S matrix and the short-range nature of strong interactions. In the more distant future I hope we may see the day when the scattering experiments will be sufficiently detailed that the dispersion relations will not be necessary to the interpretation of results. Then the dispersion relations may themselves be checked experimentally, rather than being assumed. I see, then, an early period of polarization experiments followed by a later period in which more extensive experimental results will be called for. For the pion-proton system the first period seems well progressed, based on measurements of differential cross section and P, the polarization. In the second period more complex experiments should be required, …

Approximately five years ago, the Safe, Secure Dismantlement program was started between the United States and countries of the Former Soviet Union (FSU). The purpose of the program is to accelerate progress toward reducing the risk of nuclear weapons proliferation, including such threats as theft, diversion, and unauthorized possession of nuclear materials. This would be accomplished by strengthening the material protection, control, and accounting systems within the FSU countries. This paper describes: the process involved, from initial contacting to project completion, for the physical protection upgrades now in place at the LNRC; the intervening activities; and a brief overview of the technical aspects of the upgrades.
