%X Chameleon fields evade gravitational tests in the solar system and the laboratory while playing the role of quintessence on cosmological scales. They could be produced in magnetised regions of the inner sun, e.g. around the tachocline. Once produced, they can be backconverted into X-ray photons in the sun's atmosphere or reach helioscope detectors on earth where the spectrum of photons is typically peaked in the sub-keV region. Dedicated laboratory shining-through-a-wall experiments using powerful X-ray lasers could be used to test the existence of chameleons.
