Available in PDF, EPUB and Kindle. Book excerpt: A 750 MeV electron beam test facility at Fermilab is in the planning and early construction phase. An existing building is being converted for this facility. The photoinjector currently in use at the Fermilab NICADD Photoinjector Laboratory (FNPL) will be moved to the new facility and upgraded to serve as an injector for a beam acceleration section consisting of three TTF or ILC-type RF cryomodules. A low energy off-axis beamline will be constructed to test ILC crab cavity designs and provide opportunities for other tests. Downstream beamlines will consist of a diagnostic section, a beam test area for additional beam experiments, and high power beam dumps. The initial program for this facility will concentrate on testing ILC-type cryomodules and RF control with full ILC beam intensity. A future building expansion will open up further possibilities for beam physics and beam technology experiments.

Available in PDF, EPUB and Kindle. Book excerpt: The Advanced Superconducting Test Accelerator (ASTA) is being constructed at Fermilab. The existing New Muon Lab (NML) building is being converted for this facility. The accelerator will consist of an electron gun, injector, beam acceleration section consisting of 3 TTF-type or ILC-type cryomodules, multiple downstream beam lines for testing diagnostics and conducting various beam tests, and a high power beam dump. When completed, it is envisioned that this facility will initially be capable of generating a 750 MeV electron beam with ILC beam intensity. An expansion of this facility was recently completed that will provide the capability to upgrade the accelerator to a total beam energy of 1.5 GeV. Two new buildings were also constructed adjacent to the ASTA facility to house a new cryogenic plant and multiple superconducting RF (SRF) cryomodule test stands. In addition to testing accelerator components, this facility will be used to test RF power systems, instrumentation, and control systems for future SRF accelerators such as the ILC and Project-X. This paper describes the current status and overall plans for this facility.

This book was released on 2011 with total page 3 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fermilab's Superconducting RF Beam Test Facility currently under construction will produce electron beams capable of damaging the acceleration structures and the beam line vacuum chambers in the event of an aberrant accelerator pulse. The accelerator is being designed with the capability to operate with up to 3000 bunches per macro-pulse, 5Hz repetition rate and 1.5 GeV beam energy. It will be able to sustain an average beam power of 72 KW at the bunch charge of 3.2 nC. Operation at full intensity will deposit enough energy in niobium material to approach the melting point of 2500 C. In the early phase with only 3 cryomodules installed the facility will be capable of generating electron beam energies of 810 MeV and an average beam power that approaches 40 KW. In either case a robust Machine Protection System (MPS) is required to mitigate effects due to such large damage potentials. This paper will describe the MPS system being developed, the system requirements and the controls issues under consideration.

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.

Book excerpt: The Fermilab/NICADD photoinjector laboratory is a 16 MeV electron accelerator dedicated to beam dynamics and advanced accelerator physics studies. FNPL will soon be capable of operating at (almost equal to) 40 MeV, after the installation of a high gradient TESLA cavity. In this paper we present the foreseen design for the upgraded facility along with its performance. We discuss the possibilities of using of FNPL as an injector for the superconducting module and test facility (SM & TF).
Download or read book Beam Test of a Superconducting Cavity for the Fermilab High brightness Electron Photo injector written by and published by . This book was released on 1999 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: An electron photo-injector facility has been constructed at Fermilab for the purpose of providing a 14 18 MeV elec-tron beam with high charge per bunch (8 nC), short bunch length (1 mm RMS), and small transverse emittance [1]. The facility was used to commission a second-generation photo-cathode RF gun for the TeSLA Test Facility (TTF) Linac at DESY [2, 3]; in the future, the Fermilab electron beam will be used for R & D in bunch length compres-sion, beam diagnostics, and new acceleration techniques. Acceleration beyond 4 MeV is provided by a 9-cell super-conducting cavity (see Figure 1). The cavity also provides a longitudinal position-momentum correlation for subse-quent bunch length compression. We report on the RF tests and a first beam test of this cavity.

Available in PDF, EPUB and Kindle. Book excerpt: In the context of the evaluation of possibly using the Fermilab Electron Cooler for the proposed low-energy RHIC run at BNL, operating the cooler at 1.6 MeV electron beam energy was tested in a short beam line configuration. The main conclusion of this feasibility study is that the cooler's beam generation system is suitable for BNL needs. The beam recirculation was stable for all tested parameters. In particular, a beam current of 0.38 A was achieved with the cathode magnetic field up to the maximum value presently available of 250 G. The energy ripple was measured to be 40 eV. A striking difference with running the 4.3 MeV beam (nominal for operation at FNAL) is that no unprovoked beam recirculation interruptions were observed. Electron cooling proposed to increase the luminosity of the RHIC collider for heavy ion beam energies below 10 GeV/nucleon [1] needs a good quality, 0.9-5 MeV electron beam. Preliminary design studies indicate that the scheme of the Recycler's electron cooler at FNAL is suitable for low-energy RHIC cooling and most parts of the cooler can be re-used after the end of the Tevatron Run II. To analyze issues related to the generation of the electron beam in the energy recovery mode and to gain experience with the beam transport at lower beam energy, a dedicated study was performed at FNAL with a beam run through a short beam line (so called U-bend). This report summarizes our findings and observations in the course of the measurements.
