  Cryogenic thermoacoustic oscillations is an area of interest of several
studies. For superconducting accelerators, it is an unwanted phenomena that we
usually want to get rid off. The SPIRAL2 superconducting accelerator had
distributed Taconis all over its cryostats. This paper spans the different
steps from their first detection to their damping with a highlight on the
methods and the instrumentation that has been used. The presented study also
sets the ground for a real life experimental investigation of thermo-ascoustics
in complex geometries such as superconducting LINACs. With modern Big data
analysis and simulation tools, it also sets the ground for the developments of
new data linked codes that fit these complex situations.
