  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.

  Wire-scanners with micrometer resolution are in operation at SwissFEL and FERMI for measurements of the beam emittance and for beam profile monitoring (*,**). In addition, both laboratories are developing and testing innovative nano-fabricated wire-scanners capable of providing sub-micrometer resolution and being quasi non-destructive to the beam. Nano-fabricated wire-scanners with a free-standing design (***) and a sub-micrometer resolution (****) has been already successfully tested. In the present work, innovative nano-fabricated wire-scanners joining both features of a free-standing design and sub-micrometer resolution are presented. Experimental tests carried out at SwissFEL demonstrated the capability of such innovative wire-scanner solutions to resolve transverse profiles of the electron beams with a size of 400-500 nm without incurring in any resolution limit constraint and with a minimal beam perturbation. An overview on current status and results along with future developments of these nano-fabricated wire-scanners are here presented.
