DESCRIPTION:Speakers: Pavel Kanonik (Budker Institute of Nuclear Physics)\
 nCircularly polarized photons are widely used for conducting experiments t
 o study the magnetic structures of matter. On the basis of superconducting
  coils developed at the Budker Institute of nuclear physics for a short-pe
 riod superconducting planar undulator\, a superconducting elliptical undul
 ator with a period of ~2.2 cm and an elliptic coefficient of ~ 0.7 is prop
 osed. The poles of the upper and lower halves of the undulator are located
  at an angle of 45 degrees to each other in the horizontal plane\, which c
 reates a periodic vertical and horizontal elliptical field of up to 1 T ve
 rtically and 0.7 T horizontally. There is a possibility to create a fast s
 witching  left and right polarizations of radiation at a zero angle from t
 wo sequentially installed undulators by quickly switching the electron orb
 it using correction magnets external to the cryostat (up to hundreds of He
 rtz). A short prototype of an elliptical superconducting undulator was mad
 e and magnetic measurements were made in the bath cryostat. The paper pres
 ents numerical calculations of the undulator fields\, its spectra\, and th
 e experimentally measured field.\n\nhttps://indico.inp.nsk.su/event/24/con
