The high-resolution Fourier diffractometer (HRFD) operates at the IBR-2 pulsed reactor, on which the correlation method of data registering has been implemented using a fast Fourier chopper and specialized electronics. A wide-aperture ring back-scattering detector for HRFD has been developed. The detector consists of six Z n S ( A g ) / 6 L i F-scintillation rings, each one of which is divided into 12 sections. Main parameters of this detector: covered solid angle 2 θ = ( 133 - 175 )°; ω d ≈ 2.0 sr; average absorption efficiency 85 %, geometric contribution to resolution Δd / d < 0.0005. The concept of a detector and its data acquisition system are presented.
