A new one-coordinate gaseous detector for WAXS experiments (OD4)

A one-coordinate gaseous detector of soft X-ray photons for WAXS experiments has been designed. The detector operates in counting mode and is based on multi-stage Gas Electron Multiplier (GEM). The main characteristics have been measured with the prototype having 0.4 mm pitch of readout strips. The simulation has been performed demonstrating the possibility of getting required spatial resolution with 0.2 mm channel pitch. The full-scale detector with partially connected readout structure has been fabricated and made ready for operation.
