The first superconducting wiggler, a device for generating synchrotron radiation, has been prepared for the SKIF synchrotron. It is intended for station 1-3 "Fast-flowing processes" of the Siberian Circular Photon Source Shared Use Center, has already passed all tests, and is ready for installation on the storage ring. This was reported by the press service of the facility.
A wiggler is a special magnet that changes the trajectory of an electron beam. Electrons begin to move not straight, but like a "snake," and at the same time emit synchrotron radiation. Due to this operation, a bright and powerful photon flux with adjustable energy is obtained.
The new wiggler should provide the maximum possible number of photons per electron bunch in the range from 20 to 70 keV. With a magnetic field period of only 27 mm and a required level of 2.7 T, the device showed a field margin.
The wiggler for station 1-3 was the first to complete a full test cycle. The device showed record parameters, which, according to Vitaly Shkaruba, head of the INP SB RAS laboratory, are close to the physical and technical limit and have not yet been demonstrated anywhere in the world.
At station 1-3, processes lasting millionths of a second will be studied. To do this, it is necessary to obtain a frame from a single flash of photons, so a wiggler with record parameters was created for the station, explained development coordinator Ivan Rubtsov. It is expected that the device will be installed on the ring in the autumn, after which the optical equipment will be adjusted.
