  In the near future the SLS storage ring will be upgraded for significantly higher brightness and coherence. Although the upgrade will require similar instrumentation to that already implemented for current SLS operation, significant changes in the number of devices, their specifications and their technical realizations will have to be made according to the specific requirements of SLS 2.0, using the newly available technologies and standardizations at PSI. This poster will provide an overview of the design, technical specifications, implementation and expected challenges of these systems. The beam position monitors and fast-orbit feedbacks are not included in this presentation.

The resolution of a streak camera system strongly depends on the slew rate of the deflecting element, which is the product of the amplitude and frequency of the device. An attractive approach towards femtosecond and sub-femtosecond range consists in using terahertz-driven devices, which offer a good combination of high frequency and high gradient-gradients of GV/m have been demonstrated in split ring resonator using pulse created by rectifying ultrashort laser pulses. We present results obtained from a beam experiment at the VELA facility at Daresbury laboratory. We tested a planar resonator derived from the geometry of a split ring resonator with an aperture for the beam of 20 um.
