Abstract Rapid growth in the size and performance of the detector arrays unavoidably faced the morphology concern which was susceptible to peripheral exertions. Ex-situ interferometer characterization was carried out to modelling the effect of vacuum on the morphology whose results, in turn, was used to build the ANSYS model. The modelled total deformation explained the physical phenomena very well.

Optics Design

The last decade has seen a renaissance of machine-physics studies and technological advancements that aim to upgrade at least 15 synchrotron light sources worldwide to diffraction-limited storage rings. This is expected to improve the average spectral brightness and transversally coherent fraction of photons by several orders of magnitude in the soft- and hard-X-ray wavelength range, at the expense of pulse durations longer than ∼80 ps FWHM. This paper discusses the compatibility of schemes for the generation of sub-picosecond photon-pulse durations in synchrotron light sources with standard multi-bunch user operation and, in particular, diffraction-limited electron optics design. The question of this compatibility is answered taking into consideration the storage ring beam energy and the constraint of existing synchrotrons' infrastructure. An alternative scheme for the upgrade of medium-energy synchrotron light sources to diffraction-limited storage rings and the simultaneous production of picosecond-long photon pulses in a high-gain free-electron laser scheme are illustrated.

And Performance

Charge accumulation often occurs in electron optics equipment and interferes with their operation. The trouble can be handled by using the electron flood gun. However, there are still some scenarios where neutralization is not as desired. To achieve a better charge neutralization effect and to facilitate work in confined spaces, a small size, low-energy electron flood gun providing a large area and uniform electron beam has been required. This article employs Munro’s Electron Beam Software (MEBS) to simulate the effect of the structure parameters on the performance of the beam. Based on the simulation results, the electron flood gun is processed and assembled. To verify the performance of the electron flood gun, this paper proposes a new “pinhole scanning method”. By using the method, we have achieved in-situ measurements of beam current and beam spot. The experimental results generally match the simulation results, which demonstrates that the electron flood gun has good performance and is likely to have many applications.
