    The author has illuminated some of the questions which appear to cloud constructive builder - user relations. Each of the questions has a common feature: the problems will not be solved by extreme, one-way solutions; these problems are a feature of a new era of experimentation using large shared instruments. On the one hand, the objectives and the fundamental interest are just as "academic" as the... View full abstract»

    Techniques of aligning linear accelerators are discussed with specific reference to the alignment system of the two-mile accelerator. This system uses a "three-point" method by which a point which is to be aligned is brought into coincidence with the line as defined by its end points. The end points are a laser and a photo-electric detector. A rectangular Fresnel lens is located at each point to b... View full abstract»

    The 200-BeV proton synchrotron being proposed by the Lawrence Radiation Laboratory is about 1 mile in diameter. The tolerance for accuracy in vertical placement of magnets is ±0.002 inches. Because conventional high-precision optical leveling to this accuracy is very time consuming, an alternative method using an extended mercury-filled system has been developed at LRL. This permanently installed... View full abstract»

    In this paper, we investigate the beam phase damping techniques employed in the ZGS. Phase oscillation frequencies have been measured at various times during acceleration. Response data taken on all systems involved with phase and radial position measurement have been used to calculate the phase and radial position responses. These results compare favorably with responses measured on the ZGS with ... View full abstract»

    A time-sharing pulse multiplex system is described which will perform most of the control and monitoring functions for the Cornell 10-GeV electron synchrotron. Beyond the reduction in the number of cable runs and the more compact presentation of data at the control desk made possible by this system, the control language is also suited for communication with a computer.

    Each klystron of the SLAC accelerator feeds four consecutive 10-foot accelerator sections through approximately 25 feet of earth shielding. The high power waveguide network which divides and guides the power to the four sections is adjusted so that the rf waves traveling within the accelerator sections are, at the end of each section, phased within ± two degrees of an ideal wave traveling at the ...

    We discuss the philosophy of an accelerator instrumentation system, and techniques which have been worked out for handling the various remote sensory and control functions required for proper operation of the accelerator. Lack of time prohibits more than incidental reference to philosophy of operation of the machine. View full abstract»

    Obtaining and keeping a satisfactory closed beam orbit is a major problem in the design of large accelerators. The system determining this orbit has many variables, these variables are distributed around the accelerator structure, and the existence of the beam is periodic. The designer may attempt to ensure satisfactory values for these variables by brute-force techniques such as ultra-precision c... View full abstract»

    The beam handling apparatus and its associated remote control arrangements are described for the NRL Cyclotron Beam Transport System. The need for reducing duplication of controls and power supplies for such a multi-beam-path facility resulted in the development of a rapid master selector system which can be programmed to accommodate the different beam path requirements. All ion optics and beam se... View full abstract»

    The rf system of a proton synchrotron requires a frequency-modulated rf voltage to accelerate the particles. This paper discusses a unique method for frequency modulation of rf cavities by means of a "Loud Speaker" type of mechanical rf tuning system of the type originated by W. Schnell of CERN. A typical mechanically tuned rf system for a medium-energy high-repetition-rate particle accelerator is... View full abstract»

    As part of a recent 9.6-million-dollar improvement and modernization program, an external proton beam was created for the Bevatron. During the period 1960 to 1963, the equipment necessary to produce this beam was designed, fabricated, and installed. The first external beam emerged from the Bevatron in February 1963.

    The basic synchronizing pulse in the P.P.A., tying the injection pulse and the R. F. to the magnetic field, is derived from the total current flowing through one of the Accelerator magnets. This pulse is generated in a biased toroidal coil wound on a supermalloy core, by the magnetic field H(t) created by the magnet current in a coaxial conductor. This method has provided us with a synchronization... View full abstract»
