In these last years, we have developed several diagnostics tools that allow us a better characterization of these instabilities. The Synchrotron Radiation Interferometry has been equipped with a Fast Gated Camera (FGC) to measure the bunch-by-bunch beam size evolution, which, in combination with the diagnostics tools of the Transverse Multibunch Feedback system, provides us with a fruitful insight of these phenomena. This paper describes these diagnostics tools, and as an example, compares the emittance and tune evolution switching on/off some of the vacuum pumps at the Storage Ring.
