Description

Second beam line has recently been installed and commissioned at CLEAR (CERN Linear Accelerator for Research). The line begins with a switchyard consisting of two dipole bending magnets that offset the beam from its original path, along with quadrupoles and sextupoles placed between the bends to close the first- and second-order dispersion, respectively. In this work, based on analytical methods and numerical simulations, we present a concept for an emittance exchange scheme realized using the switchyard. We show that transverse-to-longitudinal phase space exchange can be achieved by activating a transverse deflector located upstream, together with an additional deflector downstream (the only missing element). Furthermore, we demonstrate that such a scheme enables advanced beam phase-space tailoring and expands the CLEAR beam parameters beyond its nominal operational range.
