To the Acceleration of Charged Particles with Travelling Laser Focus

We describe here the latest results of calculations with FlexPDE code of wake-fields induced by the bunch in micro-structures. These structures, illuminated by swept laser bust, serve for acceleration of charged particles. The basis of the scheme is a fast sweeping device for the laser bunch. After sweeping, the laser bunch has a slope ~45o with respect to the direction of propagation. So the every cell of the microstructure becomes excited locally only for the moment when the particles are there. Self-consistent parameters of collider based on this idea allow consideration this type of collider as a candidate for the near-future accelerator era.

Wiggler for CESR operation at 2 GeV

For low energy operation strategy we advocate utilization of many short wigglers in contrast with single long wiggler. This allows begin to operate very naturally with few strong field wigglers giving necessary damping time on expense of energy spread. By adding more and more wigglers in the ring, as these wigglers are manufactured and tuned, the field in the wigglers will be decreased, keeping necessary damping. This strategy allows the mostly effective operation of CESR with minimum down time. This also gives flexibility in operation in wider energy scale without non-reversible modifications.

Compact Gantry System for the Irradiation of Lying Patient by Proton/Ion beam

We describe here a compact gantry system, when the lying patient is slowly moved in horizontal and vertical directions in accordance with rotation of transport channel around its axis so that the region, irradiated from different directions, stays in a focus of beam optical system. By this combination of rotation of magnets and linear motion of patient it becomes possible to simplify magnetic system significantly.

High Power Polarized Positron Source

We discuss the basis of polarized positron production by low energy polarized electrons. Efficiency of conversion ~0.1-1% might be interesting for CEBAF facility and ILC as well.

Usage of Liquid Metals in the Positron Production System of Linear Collider

In this publication we collected descriptions of some installations with liquid metals which could be used for high-energy colliders, ILC particularly, for the purposes of targeting, collimation, cooling, collection of secondary particles etc. Some important components of the system with liquid metals, such as pumps, nozzles, windows, and the fluid dynamics in the Lithium lens are described also.

Iron-free detectors for future linear colliders

We continue consideration of Iron-free magnetic systems for possible application in detectors for high energy collider. In particular we suggest a new type of magnetic system with the multiple flux-return solenoids. This system allows reaching higher field level at IP compared with traditional ones.

Another Detector for the International Linear Collider

We describe another detectora designed for the International Linear Collider based on several tested instrumentation innovations in order to achieve the necessary experi- mental goal of a detecter that is 2-to-10 times better than the already excellent SLC and LEP detectors, in particular, (1) dual-readout calorimeter system based on the RD52/DREAM measurements at CERN, (2) a cluster-counting drift chamber based on the successful kloe chamber at Frascati, and (3) a second solenoid to return the magnetic flux without iron. A high-performance pixel vertex chamber is presently undefined. We discuss particle identification, momentum and energy resolutions, and the machine-detector interface that together offer the possibility of a very high-performance detector for $e^+e^-$physics up to $\sqrt{s} = 1$ TeV.

The 4th Concept Detector for the International Linear Collider

The 4th Concept detector presently being designed for the International Linear Collider introduces several innovations in order to achieve the necessary experimental goal of a detecter that is 2-to-10 times better than the already excellent SLC and LEP detectors. We introduce a dual-readout calorimeter system, a cluster counting drift chamber, and a second solenoid to return the magnetic flux without iron. We discuss particle identification, momentum and energy resolutions, and the machine-detector interface that together offer the possibility of a very high-performance detector for e^+e^-physics up to $\sqrt{s} = 1$ TeV.
