Brief summary of staffing levels at Fermilab during initial construction years

Description: This paper very briefly summarizes the work of the various groups that were involved from the beginning through the end of the initial construction phase of the Fermilab project (defined here to be July 1, 1972) and the final construction or completion phase which is here defined as December 31, 1973. The numbers in this report have been gathered by examining the personnel records of Fermilab with the research being done by Chuck Marofske, the Head of Laboratory Services and his staff and by as… more

Heavy ion fusion year-end report, April 1, 1983-September 30, 1983

Description: Some highlights of the program during this reporting period are as follows: (1) First results with the completed apparatus of the Single Beam Transport Experiment (SBTE) have shown the stable propagation of a space-charge-dominated cesium-ion beam through 41 periods of an AG focussing lattice. The space-charge effects were large enough to depress the betatron phase advance per cell from sigma/sub 0/ = 60/sup 0/ to sigma = 12/sup 0/. (2) Understanding of the reflection stabilization of longitudi… more

Heat conduction thru supports between 300/sup 0/K and 4/sup 0/K

Description: Of fundamental importance in the design of any superconducting machinery is a reasonable prediction of the heat flow between the outside world at 300/sup 0/K and a helium volume at roughly 4/sup 0/K. As machines grow larger and energy costs higher the accuracy with which these estimates are made becomes more critical. Unfortunately, as cryogenic vessels become more complex so does the procedure for making estimates accurately.

Squid based beam current meter

Description: A SQUID based beam current meter has the capability of measuring the current of a beam with as little as 30 x 155 antiprotons (with a signal to noise ratio of 2). If low noise dc current is used to cancel most of the beam or an up-down counter is used to count auto-resets this sensitivity will be available at any time in the acumulation process. This current meter will therefore be a unique diagnostic tool for optimizing the performance of several Tev I components. Besides requiring liquid heli… more

Combined function magnet profile design

Description: Conformal mapping has been used in the past to generate magnet poleface contours. The present effort extends a notion considered previously in which a plane of symmetry was introduced. One further mapping permits the plane of symmetry to be transformed into a curved surface of bifurcation. A magnetostatic problem set on one side may be continued into the other side thereby providing an exact solution on both sides. An application is made for the Beijing Synchrotron booster magnet.

Accelerating heavy ions in Fermilab

Description: Recently several laboratories initiated discussions on the design and construction of high energy heavy-ion colliders to study the formation and the characteristics of quark/gluon plasma. The beam energies considered are > 30 GeV/nucleon and the costs of the machines considered are all in the hundreds of megabuck class. We consider here a poor-man's scheme of entering into a first phase of such studies.

Positron acceleration to 200 MeV

Description: 220 MeV is the energy that has to be obtained in routine operation. A standard 12m girder with SLED II can give 220 MeV minus a few percent due to not riding at the crest of the wave. In order to have the 200 MeV with only one girder, a klystron at full power all the time would be required - kept brand new. Then, for safety it is necessary to use two klystrons as designated in the SLC design. Having two klystrons gives freedom for the choice of the best arrangement. Since there will be excess r… more

Study of the tevatron nonlinear acceptance by computer simulation

Description: In this report, the results of computer calculations of nonlinear acceptance reduction caused by nonlinear fields in the TEVATRON are presented. A set of test particles has been traced during many revolutions in the accelerator in order to determine the maximum stable amplitude in the presence of nonlinear fields. Sources of nonlinear fields are designed imperfections of dipole and quadrupole magnets, fluctuations due to manufacturing tolerances, and sextupole fields needed to compensate for ch… more

Shape algorithm for a RFQ vane

Description: The Radio Frequency Quadrupole Linear Accelerator (RFQ) proposed by Kapchinskii and Teplyakov, has become an accepted structure in the accelerator community. The first working model was developed at Los Alamos for the 440 MHz cavity, and since then 200 MHz models have appeared at BNL, CERN, LBL, and KEK. The RFQ is very useful bunching low-energy ion beams and accelerating them to sufficient energies for injection into a linear accelerator. A Fermilab model of the RFQ would be a 200 MHz structu… more

Tune shifts for coasting beams crossing at small angles

Description: Results are presented for the beam-beam nu-shifts for beams crossing at a small angle ..cap alpha... The beams are not round and have elliptic gaussian charge distributions. The conditions under which the results are valid are discussed. The results include long range effects, and effects of the cut-off of the beam-beam interaction. The theoretical results are compared with those obtained by numerical computation.

Optical transition radiation from a thin carbon foil: a beam profile monitor for the SLC

Description: This memo considers placement of an ultra thin carbon foil into the SLC beam. Transition radiation light would be emitted from the surface of the foil. The optical spot from the foil could be viewed with a microscope objective lens and registered with an image detector. Multiple scattering for the foil thicknesses necessary will not affect the beam emittance. Calculations show that a thin carbon foil can withstand the electron beam if the electron beam is larger than 10 ..mu..m in size. There a… more
