Status of the intense pulsed neutron source

Description: Fortunately in spite of some premature reports of its impending demise, IPNS has passed the fourth anniversary of the first delivery of protons to the targets (May 5, 1981) and is approaching the fourth anniversary of its operation as a scattering facility (August 4, 1981). On June 10, 1984, the RCS delivered its one billionth pulse to the IPNS target - the total number of protons delivered to the targets amounted then to 75 stp cm/sup 3/ of H/sub 2/ gas. Since startup IPNS has improved steadil… more

Operating experience with the resonance extraction slow spill control system at the Zero Gradient Synchrotron

Description: Simultaneous resonance extraction to two proton lines became operational in spring of 1975. The spill quality was initially poor due to 100 percent structure in the two to six kHz range. A description is given of the empirical techniques developed to provide a smooth spill. These techniques consist of applying radial or azimuthal disturbances to the proton beam. It was found that the most effective disturbing frequency depends uniquely on the beam momentum. Quite an array of new equipment had t… more

High energy polarized deuterons at the Argonne National Laboratory zero gradient synchrotron

Description: Modifications made on the ZGS to allow the acceleration of polarized deuterons and the operational experiences with the first production run with this beam are described.

Negative hydrogen ion injection into the Zero Gradient Synchrotron

Description: In October 1976 the Zero Gradient Synchrotron (ZGS) became the first high energy proton synchrotron to use charge exchange injection in routine operations. Conversion to H/sup -/ injection has been very successful, yielding record high beam intensities within the first month of use and normal (>90 percent) operating efficiencies within the second month. A brief discussion is given of the history of H/sup -/ at the ZGS, the hardware uniquely associated with charge exchange injection, and the ope… more

Intense pulsed neutron source accelerator status

Description: The Intense Pulsed Neutron Source (IPNS) facility has been in operation since November 1, 1981. From that date through August 1, 1983, the accelerator system was scheduled for 7191 hours of operation. During this period, 627 million pulses totaling about 1.1 x 10/sup 21/ protons were delivered to the spallation target. The accelerator has exceeded goals set in 1981 by averaging 8.65 ..mu..A over this two year period. This average beam current, while modest by the standards of proposed machines,… more

Status report on the Rapid-Cycling Synchrotron

Description: The Rapid Cycling synchrotron (RCS), originally designed as an injection energy booster for the Zero Gradient Synchrotron (ZGS), operated under constraints imposed by ZGS operation until December 1979. Once these restraints were removed, the RCS made rapid strides toward its near-term goals of 8 ..mu..A of protons for Argonne National Laboratory's Intense Pulsed Neutron Source program. Reliable 30-Hz operation was achieved in the spring of 1980 with beams as high as 2 x 10/sup 12/ protons per p… more
