The LHC Transverse Damping System
(JINR's participation in the "LHC Damper" project)

Project leader:	V.M. Zhabitsky
Deputy:	N.I. Lebedev

Scientific Programme:
The LHC Transverse Damping System (ADT) is constructed in the framework of the LHC project at CERN. The system will be used for preventing transverse coupled bunch instabilities, for damping the transverse injection errores, and for excitation of transverse oscillations for beam measurements. The broadband power amplifiers and the deflectors for the LHC ADT were designed and are being constructed at the LPP (JINR) in collaboration with AB-RF (CERN). The JINR team will participate in the hardware tests and the beam commissioning of the LHC ADT as well as in the investigations of transverse beam dynamics with the aim of obtaining the ultimate beam parameters at the LHC. Results of research studies and spin-off from design work will be used for R&D studies and construction of the transverse feedback systems and the power electronics at the accelerators of the JINR and other scintific centres.
Expected main results of R&D studies:

Construction of the Transverse Damping System (TDC) at LHC, optimization of regimes of the systems for obtaining the design beam parameters in LHC.
Researches on beam dynamics in synchrotrons. Recommendations on aplication of transverse damping systems in synchrotrons (nuclotron, ets.).
Application of modern powerful wideband electronics in accelerators with purpose of increasing of theirs efficiency.

Expected main results in 2007:

Tests of kickers of TDS at JINR and CERN, completion of manufacture and tests of spare units. Participation in the hardware commissioning of the LHC Damper and in the tests for optimization of the LHC Damper operation.
Investigation of transverse dynamic of a beam for damping of particles' injection errors in the LHC for design and tests"'regimes. R&D studies for usage of TDS in nuclotron at JINR. Joint research with GSI in framework of the SIS100 & SIS300 Dampers (FAIR, GSI).
Continuation of construction of a data acquisition system and a stabilization system for power suppliers of magnetic lens and accelerating sections at LIU-3000 electron linac of LPP at JINR (in accordance with contract).
