Does particle radiation heat the test masses?
Various estimates put the temperature rise at around 1 mK per pass through the South Atlantic Anomaly. If the heat could not be dissipated, it would accumulate until the masses warmed above the superconducting transition, about half way through the mission . Fortunately the thermal emissivity of the surface, although small, is big enough to limit the temperature rise to a few Kelvin. This disturbance is at a fixed frequency, that of passages through the SAA; so it can be identified and distinguished from the EP signal frequency.
