    "abstract": "An idea of producing a focused parametric X-ray radiation (PXR) is presented.\nThe PXR is emitted by relativistic charged particles channeling along a bent\ncrystal. Then the PXR emitted from the whole length of the bent crystal is\ngoing to the focus. Some properties of focused PXR are estimated for typical\nexperimental conditions and possible applications are discussed. The experiment\nfor observation of focused PXR is proposed.",
