Applications of the Double Slit Interferometer for Transverse Beam Size Measurements at BESSY II — •Marten Koopmans^1,2, Ji-Gwang Hwang¹, Andreas Jankowiak^{1, 2}, Peter Kuske¹, Markus Ries¹, Andreas Schälicke¹, and Gregor Schiwietz¹ — ¹Helmholtz-Zentrum Berlin, Deutschland — ²Humboldt-Universität zu Berlin, Deutschland

For the upgrade of the BESSY II storage ring to BESSY VSR * an interferometric beam size monitor was designed and set up. Since this system uses visible light it can be upgraded efficiently to provide bunch resolved measurements. These are required for machine commissioning, development and to ensure long term quality and stability of user operation of BESSY VSR. Various applications of the system are outlined and measurements are presented. A detailed estimation of possible error contributions is given and the upgrade of the present system with an ICCD will be discussed.
