Initial Accelerators
摘要
It all started hundred years back from now when the path-breaking results of the fundamental research of Lord Rutherford, J.J. Thompson, and others sparked the future possibilities of atomic physics from 1919. Today, we acknowledge our deepest gratitude to the torchbearers and front-runners, who guided us throughout to draw the road map of developing particle accelerators in stages to reach the spectacular height over the years which will take endless pages to record and describe their dedication and appreciate their achievements. The description of primary part about particle accelerator is available in textbooks to strengthen the foundation and for conscientious readers the reports on the sequence of events leading to generating higher voltages and subsequent progress of developing higher energies for initial particle accelerators are available in various technical literatures. However, to refresh the stages of such developments which continued at a very slow pace from 1920 to end of World War II are highlighted in brief to emphasize the enormity of the task and the hurdle faced from the beginning by the most talented scientists and engineers to all who are interested to know little more and identify the path that led to the right direction to reach at the present stage. At the beginning, it will be appropriate to acknowledge once again, our gratitude to hundreds of prominent scientists and engineers for their contribution, dedication, relentless effort, and guidance in different fields and giving us this opportunity to share their experiences in the triumphant journeys supporting the course of advancement of particle acceleration. The evolution of initial accelerators can be compared to the invention of fire in the prehistoric era. The woods were there, but the technology of lighting the woods was not known. Three path-breaking equations expressed below bounded and distinctly defined in general forms considered fundamental to the design of particle accelerators were well established (Bryant n.d.) but transforming the theoretical equations into reality and developing the practical concept of acceleration came after a long struggle.
