MOPF03	Electron Lenses and Cooling for the Fermilab Integrable Optics Test Accelerator	electron, optics, proton, space-charge	32
	G. Stancari, A.V. Burov, V.A. Lebedev, S. Nagaitsev, E. Prebys, A. Valishev Fermilab, Batavia, Illinois, USA
	Funding: Fermilab is operated by Fermi Research Alliance, LLC, under Contract DE-AC02-07CH11359 with the US Department of Energy. Recently, the study of integrable Hamiltonian systems has led to nonlinear accelerator lattices with one or two transverse invariants and wide stable tune spreads. These lattices may drastically improve the performance of high-intensity machines, providing Landau damping to protect the beam from instabilities, while preserving dynamic aperture. The Integrable Optics Test Accelerator (IOTA) is being built at Fermilab to study these concepts with 150-MeV pencil electron beams (single-particle dynamics) and 2.5-MeV protons (dynamics with self fields). One way to obtain a nonlinear integrable lattice is by using the fields generated by a magnetically confined electron beam (electron lens) overlapping with the circulating beam. The required parameters are similar to the ones of existing devices. In addition, the electron lens will be used in cooling mode to control the brightness of the proton beam and to measure transverse profiles through recombination. More generally, it is of great interest to investigate whether nonlinear integrable optics allows electron coolers to exceed limitations set by both coherent or incoherent instabilities excited by space charge.

TUPF04	The MICE Demonstration of Ionization Cooling	emittance, solenoid, collider, factory	104
	T.A. Mohayai IIT, Chicago, Illinois, USA
	Muon beams of low emittance can provide the intense, well known beams for physics of flavour at the Neutrino Factory and multiTev collisions at the Muon Collider. The international Muon Ionization Cooling Experiment (MICE) will demonstrate the technique proposed to reduce the phasespace volume of the muons. In an ionization cooling channel, the combination of energy loss by muons traversing an absorbing material with reacceleration by RF cavities reduces the transverse emittance of the beam (transverse cooling). The rebaselined MICE project will deliver a demonstration of ionization cooling by Sep 2017: a central Li-H absorber, two superconducting focus-coil modules and two 201 MHz singlecavity RF modules. The phase space of the muons entering and leaving the cooling cell will be measured by two solenoidal spectrometers. All the magnets for the ionization-cooling demonstration are available at RAL and the first singlecavity prototype was tested successfully in the MTA Area at Fermilab. The design of the cooling demonstration experiment, a summary of the performance of each of its components and the cooling performance of the configuration will be presented.
