About The Position

Thin Wall Vacuum Enclosure (TWVE) Project Electron storage ring light sources rely on undulators to provide intense x-ray beams for a variety of scientific research applications. High magnetic fields are desirable, and one way to achieve this is by reducing the gap between the undulator magnets through which the electron beam circulates. Both permanent magnet undulators (operating at room temperature) and superconducting electromagnetic undulators (operating at 4.2 K) have been developed. For a given magnetic gap superconducting undulators produce higher fields, but in-vacuum permanent magnet undulators can reach smaller gaaps giving them an advantage in some cases. The thin wall vacuum enclosure (TWVE) project seeks to reduce the gap between superconducting undulator magnets to reach undulator performance levels beyond that achievable with permanent magnet technology. The low operating temperature required by superconducting technology requires the magnets to be packaged into a vacuum cryostat. Because the electron beam chamber does not need to withstand one atmosphere of external pressure, very thin (~100 micron) walls parallel to the magnet pole faces are possible. This significantly reduces the magnetic gap, thereby increasing the achievable magnetic field.
