Experimental Proof of Adjustable Single-Knob Ion Beam Emittance Partitioning

Abstract

The performance of accelerators profits from phase space tailoring by coupling of planes. The previously applied techniques swap the emittances among the three planes 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 of the emittances is preserved. This letter is on the first experimental demonstration of transverse emittance transfer along an ion beam line. The amount of transfer is chosen by setting just one single magnetic field value. The envelope-functions (beta) and -slopes (alpha) of the finally uncorrelated and re-partitioned beam at the exit of the transfer line do not depend on the amount of transfer.
