To satisfy user demands for a high-brightness, high-capacity synchrotron light source, novel multibend achromat (MBA) lattice structure has been developed the Diamond-II storage ring upgrade. This combines high-dispersion locations characteristic of hybrid MBA lattices with newly introduced midcell straight sections to allow extra insertion devices be installed. The resulting is named modified six bend (MH6BA) lattice. When adapted fit in existing 560.6 m Diamond tunnel, it reaches natural...
Negative hydrogen ions are often used for injecting protons from linacs to storage rings via charge-exchange injection. In this process, the two electrons stripped by a foil or laser produce which can be merged with an existing beam without significantly affecting its dynamics, allowing high intensities of accumulated. However, capability comes drawback that outer electron ${\mathrm{H}}^{\ensuremath{-}}$ ion has low binding energy and easily away prior This paper addresses following...
