High Field Hybrid Permanent Magnet Wiggler Optimized for Tunable Synchrotron Radiation Spectrum

Abstract

Synchrotron radiation provides a powerful tool of high brightness and tunable energy range for scientific applications in different domains such as chemistry, biology, material science and many others. The scientific community has recently shown a great interest in high-energy photons for other applications such as archaeological studies. To meet different demands, this study gives two proposals: called proposal 1: wiggler of 164 mm period and proposal 2: wiggler 98 mm period. Each proposal provides a single insertion device that can operate in the wiggler regime at high-energy range and in the undulator regime at low-energy range by simple gap adjustment. It develops the concept of insertion devices, gives a detailed study of the possible technologies, provides a simulation of the emitted photon flux by the proposed insertions, and compares the emitted radiation of each of them. It is found that proposal 1 provides 10^5 more flux in the undulator regime and 10 times more flux in the wiggler regime
