Experimental proof of adjustable single-knob ion beam emittance partitioning.
The performance of accelerators profits from phase-space tailoring by coupling of degrees of freedom. Previously applied techniques swap the emittances among the three degrees but the set of available emittances is fixed. In contrast to these emittance exchange scenarios, the emittance transfer scenario presented here allows for arbitrarily changing the set of emittances as long as the product ...
متن کاملUsing beam echo to recover transverse emittance
If the beam is injected into the ring with an offset a, it undergoes betatron oscillation. After the oscillation decoheres, the beam transverse emittance increases by ∆ε . To avoid this emittance increase one typically uses a feedback (or damper) that takes out the oscillation before it damps down. We show that using echo one can recover a fraction of ∆ε long after the beam oscillation decoheres.
متن کاملTransverse Emittance Exchange for Improved Injection Efficiency *
In most cases beam is injected into electron storage rings in the horizontal plane and off-axis. The larger the horizontal emittance of the injected beam the larger the acceptance of the ring has to be. The injected beam is usually delivered by a synchrotron. In case the vertical acceptance of the ring is sufficiently large one can take advantage of the small vertical emittance reached in well ...
متن کاملTransverse Emittance Reduction with Tapered
The idea of reducing transverse emittance with tapered energy-loss foil is proposed by J.M. Peterson in 1980s and recently by B. Carlsten. In this paper, we present the physical model of tapered energy-loss foil and analyze the emittance reduction using the concept of eigen emittance. The study shows that, to reduce transverse emittance, one should collimate at least 4% of particles which has e...
متن کاملDevelopment of beam transverse profile and emittance monitors for the CERN LINAC 4
LINAC4 is part of the CERN Large Hadron Collider injector chain upgrade (LIU) and will accelerate H− ions from 45 keV to 160 MeV, it will be the first step of the upgrade with the replacement of LINAC2 in 2018. In order to measure beam profiles along the LINAC, several SEM grid and wire beam scanner (WS) monitors will be installed between the RF cavities from 50 MeV to 160 MeV. This thesis cove...
