High Current Beam Physics in Induction Accelerators - course cancelled
Instructors:
George J. Caporaso and Yu-Jiuan Chen, Lawrence Livermore National Lab
Purpose and Audience
The purpose of this course is to introduce the students to the physics of beam transport in high current accelerators. This course is suitable for graduate students or students from other fields considering accelerator physics as a possible career. This course also can provide a broader background to engineers and technicians working in the field of accelerator technology.
Prerequisites
Familiarity with differential equations and with electromagnetic theory at the undergraduate level.
It is the responsibility of the student to ensure that they meet the course prerequisites or have equivalent experience.
Objectives
This course introduces the basic operating principles of high current accelerators (including novel ones) and beam dynamics and transport. The most important beam focusing systems and instabilities will be described with mathematical models.
Instructional Method
This course includes a series of 5 lectures during morning sessions, followed by 4 afternoon study sessions, in which we will discuss the problem sets. Problem sets will be assigned which are to be completed outside of scheduled class sessions. Two instructors will be available at all times.
Course Content
Introductory material will include discussions of applications of high current beams and principles of operation of various types of induction accelerators, including magnetic core and coreless types such as the Dielectric Wall Accelerator. Various focusing systems such a continuous and alternating solenoids, quadrupoles and ion channels will be discussed along with equations describing the beam envelope. Some basic instabilities such as cumulative beam breakup and ion-hose will be covered along with an examination of the stability of periodic focusing systems. The course will conclude with a discussion of chromatic aberration and its control including “corkscrew” growth, alignment algorithms for the focusing elements and transport strategies for high gradient induction accelerators.
Reading Requirements
Course notes will be provided by the instructor.
Credit Requirements
Students will be evaluated based on: homework assignments (80 % of final grade) and the final exam (20% of final grade).
