Control for Elliptically Polarizing Undulator at SRRC
A Sasaki-type elliptically polarizing undulator (EPU) which will be an important project of insertion device at SRRC is in the construction phase. It can produce an elliptically polarization for advance study in soft X-ray region. The precision of phase is main issue for this control system. The loads of the motor drivers vary with different magnetic force which results from changing the phase ...
متن کاملNovel Magnet Production Technique Used for an Elliptically Polarizing Undulator
A common problem for elliptically polarizing undulators (EPUs) is that the magnetic forces give a mechanical deflection in the magnet holder construction when changing the undulator phase. Gluing horizontally and vertically magnetized blocks together can increase the mechanical stability of the magnet holders. The gluing process of pairs of magnetized magnet blocks is time-consuming, expensive ...
متن کاملConceptual Design of a Hybrid-Type Elliptically Polarizing Undulator*
There are several means of generating circularly polarized light. The use of an electromagnetic helical device is very popular for the experiments using lower photon energy radiation. An advantage of the electromagnetic device is the capability of fast switching of polarization. However, due to its complicated structure and a limited maximum current, construction of a shorter period (< 100 mm) ...
متن کاملAn ultrafast x-ray detector system at an elliptically polarizing undulator beamline
An ultrafast x-ray detector system is under development at Lawrence Berkeley National Laboratory (LBNL) for application primarily to study of ultrafast magnetization dynamics. The system consists of a fs laser, an x-ray streak camera and an elliptically polarization undulator (EPU) beamline. Polarized x-rays from an EPU can be used to measure x-ray magnetic circular dichroism (XMCD) of a sample...
متن کاملNovel Designs for Undulator Based Positron Sources
At least three proposed future colliders (ILC, CLiC and LHeC) require a positron source with a yield greater than 10 e+s−1. An undulator-based positron source has the potential to provide the required yield. This design generates gamma rays by using a high energy electron beam traveling through a superconducting helical undulator. The gamma rays then pair produce in a titanium alloy target to p...
