We present a design methodology for developing ultrasmall electron injectors and accelerators based on cascaded cavities excited by short multicycle THz pulses obtained from laser-driven THz generation schemes. Based on the developed concept for optimal coupling of the THz pulse. a THz electron injector and two accelerating stages are designed. The designed electron gun consists of a ... https://ashleyshomestores.shop/product-category/twin-panel-headboard/
