Optical Layout of the TESLA 5 GeV Damping Ring
The TESLA linear collider needs damping rings to achieve the required small transverse emittances for optimum luminosity. Due to the TESLA pulse structure the damping rings are about 17 km long. The resulting unusual ratio of circumference to energy leads to a large space charge tune shift. The originally proposed damping ring [1] has thus been redesigned for higher energy. This paper describes...
متن کاملSupplementary Damping Systems for the International Linear Collider
Indispensable subsystems of the International Linear Collider (ILC) will be the damping rings, which will shrink the emittances of the electron and positron beams. This idea was first proposed by Amaldi [1]. Once the beams enter their respective main linacs, the ultra low emittances should already have been achieved in the damping rings, where the equilibrium emittances are determined by the ba...
متن کاملSimulation of the Fast Beam-Ion Instability in the TESLA Electron Damping Ring
The Fast Beam-Ion Instability is considered potentially harmful in electron storage rings with short bunch spacing and high bunch charge, as it is the case in the proposed electron damping ring of the future linear collider TESLA. It arises from interaction between a stored bunch and an ion cloud previously created by all heading bunches during a single pass. To study this e ect and to determin...
متن کاملElectron Cloud Effect in Damping Rings of Linear Colliders
Design of Linear Collider projects are in progress as a world wide collaboration. There are two possibility for the linear collider scheme: one is normal conducting cavity with X/C band power source, and another is superconducting cavity with L band power source. A positron damping ring storages positron beam during several damping time and extracts the beam with a very low emittance to a main ...
متن کاملThe RHIC Tune Measurement System
Each of the four fractional betatron tunes of RHIC (two planes, two rings) is measured with a transverse beam kicker and dedicated beam position monitor (BPM). A 15kV pulse is generated by a fast FET switch, passed through a stripline kicker, attenuated, and returned to the instrumentation control room (ICR) for monitoring. When pulsed at 3kV, the four-meter long kicker gives a gold beam at inj...
