[en] The Fermilab Booster Correction Element Power Supply System is being upgraded to provide significant improvements in performance and versatility. At the same time these improvements will compliment raising the Booster injection energy from 200 MeV to 400 MeV and will allow increased range of adjustment to tune, chromaticity, closed orbit and harmonic corrections. All correction elements will be capable of ramping to give dynamic orbit, tune and chromaticity control throughout the acceleration cycle. The power supplies are commercial switch mode current sources capable of operating in all four current-voltage quadrants. External secondary feedback loops on the amplifiers have extended the small signal bandwidth to 3 kHz and allow current ramps in excess of 1000 A/sec. Implementation and present status of the upgrade project is described in this paper. (author) 4 refs., 2 figs., 1 tab

[en] Space-charge effects on beam stabilities are studied for the proposed two-ring high-intensity Fermilab booster destined for the muon collider. This includes microwave instabilities and rf potential-well distortions. For the first ring, ferrite insertion is suggested to cancel the space-charge distortion of the rf wave form. To control the inductance of the ferrite during ramping and to minimize resistive loss, perpendicular biasing to saturation is proposed

[en] Protons to the CERN LHC will be supplied from the SPS accelerator via two new injection lines. The lines include three bending arcs for horizontal beam deflection and are characterized by a strong inclination (7.2 % maximum slope) to overcome the difference in height (40 m) between the two machines. They will be equipped with superconducting dipoles operated at a field of 5.4 T and 4.4 K.The distribution to the magnets of liquid helium in strongly inclined channels and over a distance of several hundred meters represents a considerable cryogenic challenge. A preliminary design of the cryogenic system is under way and the cooling schemes suitable to the unusual geometry are reviewed. The basic requirements of the refrigerating system and a tentative layout of the cryoplants are presented

[en] The present status and future plans for the Alternating Gradient Synchrotron are presented. The operating modes, accelerator improvement program, Booster synchrotron status, Stretcher ring proposal, and higher intensity options are described. (author) 2 refs., 6 figs

[en] The Brookhaven Alternating Gradient Synchrotron (AGS) received protons directly from a Linac and heavy ions directly from a Tandem Van de Graaf before 1992. The newly constructed Booster has been brought on line to serve as an injector for the AGS. The operational status of the acceleration of proton and heavy ions through the Booster and the AGS is reviewed. Accelerator improvement programs to increase proton intensity for physics research and to prepare heavy ion beams for RHIC injection are discussed

[en] A transition-jump system recently installed in the Fermilab Booster is described. Early results of the commissioning are presented

[en] The Fermilab Main Injector Project is a new 150 GeV synchrotron now under construction at the Fermi National Accelerator Laboratory. The FMI has been designed to support a luminosity in excess of 5x10³¹ cm^-2sec^-1 in the Tevatron proton-antiproton collider while simultaneously providing a 2 microAmp resonantly extracted 120 GeV beam which will present unique capabilities in the realm of rare neutral K decays and long baseline neutrino oscillation experiments. Expected performance characteristics of the Main Injector will be reviewed, and the status of the project and the schedule for completion will be discussed

[en] As a part of the ongoing Booster improvement project, all the available data on booster magnets are collected and tabulated. Data include not only the survey results available at present (July 2003) but the magnet moves as well. The main purpose of this exercise is not to provide a basis for the future magnet moves. Rather, the goal is to present the present knowledge on where magnets are and incorporate it into, for example, the MAD lattice file so that one can see the impact of misaligned magnets on the closed orbit in the absence of any corrections
