Planning of insertion devices for the 3-GeV Taiwan Photon Source

Abstract

The Taiwan Photon Source (TPS) is a 3-GeV storage ring with 24 straight sections for installation of insertion devices (ID), radio-frequency cavities (RF) and electronbeam injection. Most insertion devices are in-vacuum undulators to produce intense X-rays with a brilliance up to 1×10 21 photons s -1 mrad -2 mm -2 per 0.1 % bw. A superconducting wiggler is also necessary to provide higher energy in the medium-energy range of the TPS. The APPLE II elliptically polarized undulator and a longperiod undulator provide a source with circular and any linear polarization and the VUV source. Projects to investigate a superconducting undulator and a cryogenic permanent-magnet undulator are launched for energies in a range 1.5 -25 keV.

Low emittance lattice for the storage ring of the Turkish Light Source Facility TURKAY

“…Four bending magnet lattice structure is designed for main cell to get low emittance beam. The main cell consists of 4 bending magnets and 4 different type (16) quadrupole magnets. Figure 1 shows the betatron and dispersion functions of main cell.…”

“…The radiation spectrum is investigated by the example of some existing or planned insertion devices from other synchrotron radiation facilities [16] with some little changes. The amended undulator parameters are sown in Table 2.…”
