THPOPT003	A First attempt at implementing TRIBs in BESSY III’s Design Lattice	2560
	M. Arlandoo, P. Goslawski, M. Titze HZB, Berlin, Germany
	At HZB’s BESSY II and PTB’s Metrology Light Source (MLS), resonances and islands in transverse phase space are exploited in a special operation mode usually referred to as Transverse Resonance Island Buckets (TRIBs). This mode provides a second stable orbit well separated from the main orbit and one of its applications in photon science is the ultra-fast switching of the helicity of circularly polarized light pulses. In the context of the conceptual design study of BESSY III, it is under investigation how this special optics mode can be implemented in an MBA structure and how it will impact the photon source parameters. In this paper we present a preliminary attempt at implementing TRIBs in BESSY III’s design lattice, a multi-bend achromat, by breaking the symmetry of the lattice.

A First attempt at implementing TRIBs in BESSY III’s Design Lattice

At HZB’s BESSY II and PTB’s Metrology Light Source (MLS), resonances and islands in transverse phase space are exploited in a special operation mode usually referred to as Transverse Resonance Island Buckets (TRIBs). This mode provides a second stable orbit well separated from the main orbit and one of its applications in photon science is the ultra-fast switching of the helicity of circularly polarized light pulses. In the context of the conceptual design study of BESSY III, it is under investigation how this special optics mode can be implemented in an MBA structure and how it will impact the photon source parameters. In this paper we present a preliminary attempt at implementing TRIBs in BESSY III’s design lattice, a multi-bend achromat, by breaking the symmetry of the lattice.
