	Electron Lenses built and installed in Tevatron have proven themselves as safe and very reliable instruments which can be effectively used in hadron collider operation for a number of applications, including compensation of beam- beam effects, DC beam removal from abort gaps, as a diagnostic tool. In this presentation we consider a possibility of using electron lenses with hollow electron beam for ion and proton collimation in LHC.
MOPC101	Design Considerations of Fast-cycling Synchrotrons Based on Superconducting Transmission Line Magnets	301
	H. Piekarz, S. Hays, Y. Huang, V. D. Shiltsev Fermilab, Batavia, Illinois
	Fast cycling synchrotrons have become necessary components of contemporary accelerator systems for advanced nuclear and high-energy physics programs. We explore a possibility of using super-ferric dipole magnets of up to 2 Tesla B-field powered by a superconducting transmission line conductor. We present both the LTS and the HTS conductor design options for these magnets and their impact on both static and dynamic power losses with operation cycles from o.5 Hz to 5 Hz, depending on the beam energy and the size of the accelerator ring. We also discuss expected B-field quality and the corrector magnets options. We outline magnet string inter-connections and creation of space for the corrector magnets and discuss option for a superconducting dump switch of the quench protection system.
TUXG02	High Luminosity Operation, Beam-Beam Effects and Their Compensation in TEVATRON	951
	V. D. Shiltsev Fermilab, Batavia, Illinois
	During the recent years a remarkable increase of the TEVATRON luminosity was achieved. The presentation discusses the collider performance, how this was achieved and illustrates today's limitations. The TEVATRON will shutdown soon but many ideas that emerged from the TEVATRON are of great interest for future (hadron) colliders. As an example, the experience gained at the TEVATRON in understanding of beam-beam effects in hadron colliders and their compensation is highly relevant for future projects. Experimental results of the Tevatron Electron Lenses will be presented and possible use of similar lenses in LHC and RHIC will be discussed.

	MANX is an experiment to prove that effective six-dimensional (6D) muon beam cooling can be achieved a Helical Cooling Channel (HCC) using ionization-cooling with helical and solenoidal magnets in a novel configuration. The aim is to demonstrate that 6D muon beam cooling is understood well enough to plan intense neutrino factories and high-luminosity muon colliders. The experiment consists of the HCC magnets that envelop a liquid helium energy absorber, upstream and downstream instrumentation to measure the particle or beam parameters before and after cooling, and emittance matching sections between the detectors and the HCC. Studies are presented of the effects of detector resolution and magnetic field errors on the beam cooling measurements.
THPP058	Progress with Electron Beam System for the Tevatron Electron Lenses	3500

	We have developed , built and tested two novel electron guns for the Tevatron and RHIC electron lenses: the first, a gridded gun which generates electron beam profile with smoothed edges and broad flat-top; the second, Gaussian beam profile gun which can be used for generation of the profile with depressed emission in the center. We have also developed a new type of HV modulator for use in TELs. In this articel, we desicribe the guns and the modulator, and present results of the bench tests.
