KFRD

KFRD consists of two instruments FRD-A (carriage A) and FRD-B (carriage B). Instruments FRD-A and -B are fully identical. They are two independent position sensitive x-ray spectrometers. Within the detectors, the electrode planes are in two layers. The first layer is position sensitive and spectrometric, the second one - only spectrometric. The second layer is also used for anticoincidence system with the aim to reduce the charge particle background in the MWPC. All electrode planes are mounted on ceramic frames.
