Simulation results of a plasma lens as a capturing device for the ILC positron source — •Manuel Formela1, Niclas Hamann1, Gudrid Moortgat-Pick1, Klaus Floettmann2, and Gregor Loisch21Universität Hamburg — 2DESY

The ILC is an ambitious international collaboration with its positron source especially being at the forefront of pushing technological boundaries. Part of this enterprise has to be the optical matching device responsible for capturing positrons exiting a target and transforming them from a highly divergent beam with a small effective cross-section to a wide, parallel beam to be appropriate for the succeeding accelerator section. For many years this problem has been approached by different types of sophisticated coils. Today considerations exist to utilize an electric current-carrying plasma. This so called plasma lens creates a magnetic field, which is potentially especially qualified for the usage as a so called optical matching device due to its pronounced azimuthal component in contrast to the radial component of conventional devices. Simulations of various tapered plasma lens designs have been conducted to find an optimal device for the ILC positron source. Designs with linear and quadratic tapering, but also with tapering growing with the square root have been examined. Furthermore, the parameter space for the optimization included a wide range of values for entrance and exit radius, length and electric current.
