101115V. Ziemann: CAI at SFAIR meeting in Uppsala XFEL related activities Following the withdrawal of funding for CELSIUS and CRYRING the university heads of UU+SU+KTH sponsored the creation of a joint center for research in Free-electron laser related issues (2005, 3x3x1.5 MSeK) Three projects following workshop in Kista (Nov 2004) Precision fiducialization for special magnets Surface physics in small beam pipes (short bunches and resistive wakes) Optical Replica Synthesizer to measure ultra-short electron bunches in FLASH Spin-off: XFEL laser heater as Swedish in-kind contri- bution to the constrution of the EuXFEL

101115V. Ziemann: CAI at SFAIR meeting in Uppsala Optical Replica Synthesizer Problem: measure ultra-short bunches in the 10s of fs range: EOS, TEO, LOLA, ORS too fast for electronics (10 Gs/s, 100 ps) but laser folks know (autocorrelation, FROG) Solution: make an optical copy of the electron bunch and analyze that with laser methods.

101115V. Ziemann: CAI at SFAIR meeting in Uppsala CAI, the startup phase In 2007 CAI was established (B. Hjörvarsson, chair and T. Ekelöf co-chair, VZ, director) In the KOF07 evaluation the need for the functionality of CAI was clearly identified......and resulted in the funding of positions for two mechanical engineers (CAD design) from the rektor's strategic funds Close relation to the Ångström workshop. We work on a wide portfolio of projects, both in- house and externally.
