Available in PDF, EPUB and Kindle. Book excerpt: This note is an account of the authors' effort in both understanding the Booster high field orbit and controlling it through displacements of the main combined function magnets. We were able to achieve the second goal with considerable accuracy while having limited success with the first, due to insufficient knowledge of the Booster dynamics. This work was initiated in Spring 1987 with the orbit control via magnet moves the chief purpose. A series of magnet moves in 1987 and 1988 resulting from this study testified to its reliability. The understanding of the Booster orbit in general remains an ongoing process in which we keep modifying our model with the hope of eventually having a quantitative grasp of the closed orbit and being able to manipulate it with more flexibility and accuracy. In this paper we give a brief description of the Booster environment in which the magnet moves are carried out, together with background information concerning the magnet moves. The method we use is discussed. The result of the moves is documented, and our effort to understand the Booster high field orbit is given a detailed account. 12 figs., 5 tabs.

Available in PDF, EPUB and Kindle. Book excerpt: With the implementation of the BPM system in the Fermilab Booster, complete survey data of the main magnets have been employed to determine magnet moving schemes to correct the high field orbit at 8 GeV kinetic energy and to understand the global pattern of the high field orbit in both planes. Considerable success has been achieved in the former task. We also obtained reasonable understanding in the later effort, given the multitude of factors that have to be dealt with. In this paper an account is given of the survey record, the orbit correction exercise, and the effort to reconstruct the high field orbit based on the survey records. 2 refs., 7 figs., 1 tab.

This book was released on 1989 with total page 1298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cities and Their Vital Systems asks basic questions about the longevity, utility, and nature of urban infrastructures; analyzes how they grow, interact, and change; and asks how, when, and at what cost they should be replaced. Among the topics discussed are problems arising from increasing air travel and airport congestion; the adequacy of water supplies and waste treatment; the impact of new technologies on construction; urban real estate values; and the field of "telematics," the combination of computers and telecommunications that makes money machines and national newspapers possible.

Book Synopsis Development of Cogging at the Fermilab Booster by :
Download or read book Development of Cogging at the Fermilab Booster written by and published by . This book was released on 2015 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of magnetic cogging is part of the Fermilab Booster upgrade within the Proton Improvement Plan (PIP). The Booster is going to send 2.25E17 protons/hour which is almost double the present flux, 1.4E17 protons/hour to the Main Injector (MI) and Recycler (RR). The extraction kicker gap has to synchronize to the MI and RR injection bucket in order to avoid a beam loss at the rising edge of the extraction and injection kickers. Magnetic cogging is able to control the revolution frequency and the position of the gap using the magnetic field from dipole correctors while radial position feedback keeps the beam at the central orbit. The new cogging is expected to reduce beam loss due to the orbit changes and reduce beam energy loss when the gap is created. The progress of the magnetic cogging system development is going to be discussed in this paper.

Book Synopsis Improving the Fermilab Booster Emittance by :
Download or read book Improving the Fermilab Booster Emittance written by and published by . This book was released on 1988 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Demand of high luminosity in the Tevatron collider in Fermilab makes the small beam emittance coming out of the 8 GeV Booster a highly desirable feature. This is because Booster bunches with small emittance, when eventually coalesced into Main Ring bunches, will ensure a high luminosity in the collider. Efforts have been made to identify factors limiting the phase space density in both transverse and longitudinal dimensions. The experimental result points to space charge induced tune spread at low energy as the main factor limiting the transverse phase space density, and the space charge induced phase space dilution at transition and longitudinal coupled bunch instability as the factors limiting the longitudinal phase space density. To counteract these factors, a set of harmonic correction sextupoles and skew sextupoles were implemented to reduce the third order resonances in the transverse case. In the longitudinal case a .gamma./sub t/-jump system was implemented to ease the bunch tumbling after transition, and various schemes to damp the longitudinal coupled bunch instability are either implemented or being reviewed. Future plans and efforts will be mentioned briefly at the end of this article. 3 refs., 8 figs., 1 tab.

Book Synopsis Increasing the Energy of the Fermilab Booster by :
Download or read book Increasing the Energy of the Fermilab Booster written by and published by . This book was released on 1977 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Fermilab booster accelerator was originally conceived for acceleration of protons with an injection energy of 200 MeV to an extraction energy of ten GeV (to the 500 GeV main accelerator). Early booster operation has been limited to eight GeV. The booster beam will be more acceptable to the main accelerator if extraction is at ten GeV, thus the booster magnet system is now being modified for ten GeV acceleration. Regulation of the booster magnetic field for injection at 200 MeV was a task even when operating to eight GeV. An outline is given of the approach which was adopted and how it relates to the ten GeV attempt. Problems encountered in the design of any ac magnet system are discussed.
