Phase 1 Beamlines

As of now there is only a preliminary list of insertion devices (IDs) which are being considered for installation in the storage ring at phase 1. IDs for phase 2 are not yet defined, although for the purpose of beam dynamics calculations we consider more than doubling phase 1 IDs.Table 1 lists all insertion devices

Each of these IDs has impact over the properties of the beam, be it on the long term dynamic stability or on the equilibrium parameters. Figure 1 shows the effect of IDs over emittance and beam energy spread, in particular.

Commissioning Undulators

Five planar unduladors (APUs) were purchased from Kyma to be installed in the storage ring for the commisioning phase of some beamlines. Table 2 shows the relation of the IDs used in each beamline and their main parameters
