    "abstract": "A series of Silicon crystal undulator samples were produced based on the\napproach presented in PRL 90 (2003) 034801, with the periods of undulation from\n0.1 mm to 1 mm, and the number of periods on the order of 10. The samples were\ncharacterized by X-rays, revealing the sine-like shape of the crystal lattice\nin the bulk. Next step in the characterization has been the channeling tests\ndone with 70 GeV protons, where good channeling properties of the undulated\nSilicon lattice have been observed. The photon radiation tests of crystal\nundulators with high energy positrons are in progress on several locations:\nIHEP Protvino, LNF Frascati, and CERN SPS. The progress in the experimental\nactivities and the predictions from detailed simulations are reported.",
