The currentATF2 Ultra-Low beta proposalwas designed to achieve 20nm vertical IP beam size without considering the multipolar components of the FD magnets. In this paper we describe different scenarios that avoid the detrimental effect of these multipolar errors to the beam size at the interaction point (IP). [...]

Towards Ultra-Low β* in ATF2
/ Patecki, Marcin (CERN) ; Aloev, Alexander (CERN) ; Bett, Douglas (CERN) ; Kubo, Kiyoshi (KEK, Tsukuba) ; Marín, Eduardo (SLAC) ; Modena, Michele (CERN) ; Okugi, Toshiyuki (KEK, Tsukuba) ; Tauchi, Toshiaki (KEK, Tsukuba) ; Terunuma, Nobuhiro (KEK, Tsukuba) ; Tomás, Rogelio (CERN) et al.
The Accelerator Test Facility 2 (ATF2) has already demonstrated the feasibility of Final Focus Systems based on the local chromaticity correction scheme and its focusing capabilities by reaching a vertical beam size at the virtual Interaction Point (IP) of less than 50 nm. The value of the chromaticity in ATF2 is comparable with the expected chromaticity in ILC, but 4 times lower than in a design of CLIC. [...]

A nanometer beam size in the interaction point (IP) is required in case of future linear colliders for achieving the desired rate of particle collisions. KEK Accelerator Test Facility (ATF2), a scaled down implementation of the beam delivery system (BDS), serves for investigating the limits of electron beam focusing at the interaction point. [...]

The Accelerator Test Facility 2 (ATF2) aims to test the novel chromaticity correction scheme which is implemented in the final focus systems of future linear colliders such as the International Linear Collider (ILC) and the Compact Linear Collider (CLIC). The ATF2 nominal and ultralow β* lattices are designed to vertically focus the beam at the focal point, or usually referred to as interaction point (IP), down to 37 and 23 nm, respectively. [...]
