Description

Unlike traditional Transmission Electron Microscopes (TEM) Ultrafast Electron Diffraction (UED) and Microscopy (UEM) operate at higher electron energies to preserve the high quality electron beam required for unprecedented temporal and spatial resolution- This however forces stringent requirements on electron- optical components- In particular a set of high field (2 Tesla) solenoids acting as condenser, objective and projection lens are needed- While superconducting solenoids are expensive and require cryogenics, normal conducting solenoids are incredibly bulky, weighing about 2 tons each- At present there is no compact UEM optics available to enable a marketable machine- The uniqueness of the Euclid’s proposal is its utilization of a flux concentrator, a pulsed technology adopted for the design of the ILC positron target collection solenoid- Duty cycle reduction allows for a significant reduction in the size of the magnet- Pulsed operation allows a high peak magnetic field (2 Tesla) at a reasonable heat load, which can be managed by conventional cooling-
