An electromagnetic valve used to isolate the target area of an accelerator from the rest of the machine when air is entering the target chamber is described. The valve, used in the Van de Graaff machines and cyclotron of Saclay since 1957, offers quasi-instantaneous self-closing under the effects of the vacuum. (D.C.W.)

Some studies on nonlinear effects in betatron oscillations of particles circulating in accelerators were accomplished in connection with the construction of the CERN proton synchrotron. In the course of the studies it was judged advantageous to construct model to electromechanically simulate these oscillations. A description of the construction of the device and the results obtained ...
The transport of three simultaneous beams in the 1 km-length linear accelerator (linac) has been studied, from the beam recombination stage at the linac entry, to their dispersion, at the end of the linac: effects of the injection energy, the FODO mesh le...

The magnetic field topography is considered, in cylindrical coordinates, for the case of radial sector accelerators having an azimuthal periodicity and radial field index, both of them with random values. The solutions for the case where the index is a function of the radius are defined using a recurrence formula. In the case where the index is constant, these solutions are reduced to ...
