Available in PDF, EPUB and Kindle. Book excerpt: The electron cooling project requires a high current electron beam with high reliability to provide the consistent cooling required by Fermilab's physics program. We are using a 5URE-2 Pelletron to provide this beam. The program is developing a high current DC recirculating electron beam with high recovery efficiency. The present layout uses 2 sets of tubes with acceleration, a 180{sup o} bend, and deceleration for a total of about 10 meters of beam line. The project's nominal operating parameters are .5 A at 4.3 MeV with the emission cathode immersed in a 200-600 G magnetic field.

Book excerpt: The Fermilab accelerator has been in operation since 1972. The first operation was at 200 GeV, although the energy was soon raised to a nominal value of 300 GeV. Since July 1975, 400 GeV has been the normal energy. The machine was operated at 500 GeV in May 1976. The accelerator system is composed of a 750-kV Cockcroft--Walton, a 200-MeV linac, an 8-GeV to 15-Hertz booster, and a 500-GeV main ring. The linac injects one pulse into the booster and the booster injects the 8-GeV pulse into the main ring, each using single-turn injection. This process is repeated 13 times to fill the main ring circumference before accelertion begins. A switchyard system splits the extracted beam to 6 different external targets. There is one internal target area with 3 possible targets. The linac can also deliver a 66-MeV beam to a neutron cancer therapy facility and a 200-MeV proton beam to a radiography experiment. A project is being initiated to study electron cooling of 200-MeV protons. Upon successful cooling of protons, studies will begin on the cooling and accumulation of antiprotons. The antiprotons would be injected into the main ring and simultaneously accelerated with protons to produce antiproton-proton colliding beams. Work is in progress at Fermilab on the construction of a 1000-GeV superconducting Energy Doubler/Saver to be installed in the present main-ring tunnel. With both the main ring and energy doubler in the same tunnel, it is obvious proton--proton colliding beams will be possible. The complete system of 1000-GeV fixed-target physics, 250 GeV (main ring) x 1000 GeV (doubler) proton--proton physics and 1000 GeV x 1000 GeV proton--antiproton physics in the doubler has been named the Tevatron.

Available in PDF, EPUB and Kindle. Book excerpt: Fermilab's Recycler ring was used as a storage ring for accumulation and subsequent manipulations of 8 GeV antiprotons destined for the Tevatron collider. To satisfy these missions, a unique electron cooling system was designed, developed and successfully implemented. The most important features that distinguish the Recycler cooler from other existing electron coolers are its relativistic energy, 4.3 MV combined with 0.1-0.5 A DC beam current, a weak continuous longitudinal magnetic field in the cooling section, 100 G, and lumped focusing elsewhere. With the termination of the Tevatron collider operation, so did the cooler. In this article, we summarize the experience of running this unique machine.

Book excerpt: The Recycler Electron Cooler (REC) was the first cooler working at a relativistic energy (gamma = 9.5). It was successfully developed in 1995-2004 and was in operation at Fermilab in 2005-2011, providing cooling of antiprotons in the Recycler ring. After introducing the physics of electron cooling and the REC system, this paper describes measurements carried out to tune the electron beam and optimize its cooling properties. In particular, we discuss the cooling strategy adopted for maximizing the collider integrated luminosity.

Available in PDF, EPUB and Kindle. Book excerpt: The Fermilab Electron Cooling Project requires the operation of a 4.34 MeV electron beam in the same enclosure that houses the 120, 150 GeV Main Injector. Effective shielding of the magnetic fields from the ramped electrical busses and local static fields is necessary to maintain the high beam quality and recirculation efficiency required by the electron cooling system. This paper discusses the operational tolerances and the design of the beamline shielding, bus design, and bus shielding as well as experimental results from the prototype and final installation.
