Transverse Couple Bunch Instabilities (TCBI) have been identified at ALBA as one of the main beam current limitations since its early commissioning in 2011. 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.
