Abstract
Micro-Pattern Gaseous Detectors (MPGD) have opened the way for the construction of detectors whose performance surpasses that of the previous generations in terms of spatial resolution, high-rate capability and increased radiation hardness. Led by the Micro-Mesh Gaseous Structure (Micromegas) and the Gas Electron Multiplier (GEM), some MPGDs are mature technologies used in a variety of experiments at high energy physics. What we report in this article is the experience explored in the last years with a compact GEM detector system in several applications as medical imaging, dosimetry and beam diagnostics for high energy beams and for nuclear reactors. For sake of shortness, only performance on soft X-ray and neutron detection will be described in detail. Also a description of the new promising highly pixelated GEM detector will be presented.

Summary
Soft X-ray diagnostics for a burning plasma experiment have to be radiation tolerant, shielded, and must own both low sensitivity to neutrons and gammas and energy measurement capability. The X-ray signal produced in the GEM detector arrives to 7 × 106 counts/s per pixel, being three-four orders of magnitude higher than the neutron background [6]. This GEM gas detector confirmed to be flexible, with high performance, robust, pretty insensitive to neutrons and gammas, adequate for an imaging tomography. After this very preliminary and short experimental campaign, it will be fully studied and exploited at KSTAR in the coming years, in a framework of a collaboration ENEA-INFN (Italy) and NFRI-KAIST (South Korea)
