The beam position system of the Fermilab Main Ring contains one horizontal and one vertical Electrostatic Beam Pickup in each of the 96 cells of the machine. A pair of 75 ohm cables transmits the induced signal from the machine tunnel to the nearest

Transductors are used as current measuring devices in the main accelerator quadrupole power supply feedback loop and as monitors in the dipole circuit. The development of these transductors is described, starting with the basic series - connected (Kr

Nucleon structure functions obtained from neutrino and anti-neutrino scattering on iron nuclei at high energies (Ev=30 to 250 GeV) are presented. These results are compared with the results of other lepton-nucleon scattering experiments. The structur

The energy dependence of the cross section for neutrino- and antineutrino-nucleon charged-current interactions has been determined from data taken in Fermilab's dichromatic neutrino beam. $\frac{{\ensuremath{\sigma}}^{\ensuremath{\nu}}}{E}=(0.669\ifm

The NAL booster - accelerator radio-frequency system design is described in detail. This rapid-cycling system is ferrite tuned from 30 MHz to 53 MHz. Each high-power module has an RF-output rating of 100 kW provided by a cascode amplifier which is a

The input data needed for engineering computations on ferrite for cavity tuning prove to be almost nonexistent in industry or private research. It would appear that the accelerator designer's choice is either a) accept crude input data and play safe

This paper describes a high voltage pulse generator developed to deflect the beam of the 184-inch cyclotron at Berkeley, California. The apparatus develops a deflecting potential of 200 kilovolts that rises from 10% to 90% of peak value in 0.1 micros

The problem of fluctuating beam load in high-intensity cascade synchrotrons is discussed. A comparison is made of various methods of controlling rf system amplitude and phase fluctuations, with emphasis on feedback control as an economical method of

The removal of the ion beam of 190‐Mev deuterons from the magnetic field of the 184‐inch cyclotron is complicated by the fact that at large radii the ion increases its radius very little in one revolution. The usual type of deflector did not appe
