Maximal charge injection of a uniform separated electron pulse train in a drift space
A charge sheet model is proposed to study the space charge effect and uniformity of charge separation of an electron pulse train in a drift space. An analytical formula is derived for the charge density limit as a function of gap spacing, injecting energy and pulse separation. To consider the relativistic effects, the theoretical results are verified by numerical solutions up to 80 MeV. This model can be applied to the design of Smith-Purcell radiation, multiple-pulse electron beam for time resolved electron microscopy, and to free electron laser.
期刊介绍:
Physical Review Special Topics - Accelerators and Beams (PRST-AB), is a peer reviewed, purely electronic journal, distributed without charge to readers and funded by contributions from national laboratories. It covers the full range of accelerator science and technology: subsystem and component technologies, beam dynamics; accelerator applications; and design, operation, and improvement of accelerators used in science and industry. This includes accelerators for high-energy and nuclear physics, synchrotron radiation production, spallation neutron sources, medical therapy, and intense beam applications.
