Cosami/SLS-2 budget and priorities w Cosami status § § KTI proposal rejected resubmission Industrial partner • • § § interested in collaboration, faith in PSI 500 K contribution to XIL/Re. Scan inspection tool at SLS but no support for Cosami conceptual design report further decisions in August High priority for PSI now Decision on location in August • WLHA, Injector-1 bunker, parc innovaare, OBLA w SLS-2 status § no longer on SERI roadmap due to budget cut • no budget for SLS-2 until 2020 • but 60 new positions for SYN. . . § ATHOS well on roadmap, 40 M assured.

Large chromaticity schemes for SLS-2 w. i. p. ME • Realistic SLS operating scenarios include large chromaticity • A useful lever for combating impedance instabilities • Development efforts so far have been with zero or very small chromaticity, where the chromatic footprint can be confined to the half-integer box. • With larger chromaticity, the chromatic footprint cannot be squeezed into the half-integer, and must be optimized to the integer. • SLS (1) operates with large chromaticity • APS-U has been designed for +5/+5 and spans full integer • SLS upgrade operation at large chromaticity needs to be validated, and large chromaticity, large footprint SLS magnet schemes need to be developed. APS-U +5 Chromaticity SLS upgrade zero Chromaticity SLS upgrade -5 Chromaticity

Optics correction study for SLS 2 w Motivation § § MA, MB Linear optics correction is essential To reveal if LOCO style correction is applicable to SLS 2 w Results § It works well as in SLS • Residual beta-beating = 0. 2~0. 3% rms • BPM and corrector calibration accuracy ~0. 3% rms § § However, the horiz. dispersion should be corrected simultaneously Typical result AC meeting, April 13, 2016 5

JC More CAFE methods exposed to Py. Cafe web documentation in progress https: //ados. web. psi. ch/cafe/cython. html Comparison to alternatives presently in use: ~ 4 x faster than ca. Channel (Python-C API) ~ 40% faster than Py. Epics Ctypes. . . and offers rather more…. CAFE & zmsglog both installed on /opt/gfa/ start from launcher Coming soon: presentation for interested colleagues. AC meeting, April 13, 2016 10
