In this memo we discuss the physics of ponderomotive effects in superconducting cavities and identify the preparations needed to be done for performing measurements of Lorentz transfer functions atthe FREIA laboratory. Specifically, it turns out that we need a stub tuner for increasing the externalquality factor of the spoke cavity in order to be able to measure Lorentz transfer functions. Electronics required for measurements is also discussed.
