Enhanced Optical Cooling of Ion Beams for LHC
The possibility of the enhanced optical cooling (EOC) of Lead ions in LHC is
investigated. Non-exponential feature of cooling and requirements to the ring
lattice, optical and laser systems are discussed. Comparison with optical
stochastic cooling (OSC) is represented.Comment: 4 page
Self-stimulated Emission of Undulator Radiation
We attract attention that interaction of particle in downstream undulator
with its own wavelet emitted in upstream undulator could be as strong as with
the frictional field in undulator itself. This phenomenon could be used for
enhancement of signal from pickup undulators in optical stochastic cooling
methods as well as for increase of damping.Comment: 3 pages, 2 figure
Self-Stimulated Undulator Radiation and its Possible Applications
We investigated the phenomena of self-stimulation of incoherent emission from
an undulator installed in the linear accelerator or quasi-isochronous storage
ring. We discuss possible applications of these phenomena for the beam physics
also.Comment: 14 pages, 4 figure
Methods of recovery technical equipment of the city by using new trends
The article deals with the current state of technical equipment of the city, which today is generally in very poor condition. The article also discusses the current unsatisfactory conceptual and coordination solution of engineering network, there are described various reasons why accede to restore technical equipment of the city, and on this basis are described of the possibility of restoration of these buildings with the use of new trends in the field of engineering networ
Continuous Modeling of Arterial Platelet Thrombus Formation Using a Spatial Adsorption Equation
In this study, we considered a continuous model of platelet thrombus growth in
an arteriole. A special model describing the adhesion of platelets in terms of
their concentration was derived. The applications of the derived model are not
restricted to only describing arterial platelet thrombus formation; the model
can also be applied to other similar adhesion processes. The model reproduces
an auto-wave solution in the one-dimensional case; in the two-dimensional
case, in which the surrounding flow is taken into account, the typical torch-
like thrombus is reproduced. The thrombus shape and the growth velocity are
determined by the model parameters. We demonstrate that the model captures the
main properties of the thrombus growth behavior and provides us a better
understanding of which mechanisms are important in the mechanical nature of
the arterial thrombus growth
Proposal for an Enhanced Optical Cooling System Test in an Electron Storage Ring
We are proposing to test experimentally the new idea of Enhanced Optical
Cooling (EOC) in an electron storage ring. This experiment will confirm new
fundamental processes in beam physics and will demonstrate new unique
possibilities with this cooling technique. It will open important applications
of EOC in nuclear physics, elementary particle physics and in Light Sources
(LS) based on high brightness electron and ion beams.Comment: 21 pages, pdf. The number of electrons in the bunch in the example is
decreased, the volume of the paper is increased, Misprints are correcte
