AbstractAbstract
[en] The reconstruction of the Radiological Research Accelerator Facility (RARAF) at the Nevis Laboratory of Columbia University is nearing completion. In a previous report the early part of the construction of the RARAF building within the Nevis cyclotron building was described. This year we describe the completion of the building, the RARAF staff, assembly of the 4 MV Van de Graaff accelerator, and the first phase of its operation. 2 references

AbstractAbstract
[en] The up-grading transformation of the Saclay FN-Tandem asked for the replacement of the aluminum electrode accelerating tube by a new one with stainless steel electrodes, and the old (yellow) resistors of the column by a set of new (blue) resistors. The first problem to be faced with was the behavior of the vacuum conditions as a function of time. A second one was due to the instability that appeared at voltages higher than 6.5 volts. This instability problem was overcome by replacing the whole set of resistors by the set of old ones

AbstractAbstract
[en] The characteristics and performance of accelerator tubes required by the new generation of large tandem accelerators and by the upgrading of existing machines are summarized. Recent experiments on surface flashover of insulators in vacuum and on the control of surface charging are briefly reviewed current theories of the microdischarge process are examined and their relevance to the operation of UHV and conventional tubes is discussed. The role of microparticles, the evidence for their existence and their influence on breakdown is reported in the light of recent experiments using laser scattering and electron microscopy. Finally, current practice and achievements are compared with the data presented by Cranberg in 1952 and some conclusions are drawn about future progress and developments

AbstractAbstract
[en] A new material called Poly-C is recommended for carrying positive charge to the terminal of a Van de Graaff accelerator. Compared to the rubberized cotton belt, the new belt gives superior performance in every way at a much lower cost. The Poly-C can be purchased as a flat sheet and joined into a continuous loop after it has been inserted into the machine. (orig.)
