abstract = {Helioscopes are one of the most promising techniques for
axion discovery in which low background X-ray detectors are
mandatory. We report the latest developments of the
Micromegas detectors for the CERN Axion Solar Telescope
(CAST). The use of low background techniques has led to
background levels below
$10^{-6}$~c~keV$^{-1}$~cm$^{-2}$~s$^{-1}$, more than a
factor 100 lower than the first generation of Micromegas
detectors at CAST. The helioscope technique can be enhanced
by the use of an X-ray focusing device, increasing the
signal-to-background ratio. A new dedicated X-ray optic was
installed at CAST during 2014 with a low background
Micromegas in its focal plane. Apart from increasing
CAST’s sensitivity, the system has been conceived as a
technological pathfinder for the International Axion
Observatory IAXO.},
