Slide 3

Motivation

Manipulate charged particles (b+/-, ions, like p,d,a, …)

Beam lines systems

Magnetic & electric analysis/ separation (e.g. St. George)

Acceleration of ions

Slide 4

Who needs ion-optics anyway?

Over 6*109 people have - I hope so - happy lives without!

A group of accelerator physicists are using it to build machines

that enables physicists to explore the unkown!

Many physicists using accelerators, beam lines and magnet system

(or their data) needs some knowledge of ion-optics.

This lecture series is an introduction to the last group and I will do

my best to let you in on the basics first and than we will discuss

some of the applications of ion-optics and related topics.

Slide 5

Introductory remarks

Introduction for physicists  Focus on ion-optical definitions, and tools that

are useful for physicist at the NSL & future users of St. George recoil separator.

Light optics can hardly be discussed without lenses & optical instruments

 ion-optics requires knowledge of ion-optical elements.

Analogy between Light Optics and Ion-Optics is useful but limited.

Ion-optical & magnet design tools needed to understand electro-magnet systems. Ion-optics is not even 100 years old and (still) less intuitive than optics developed

since several hundred years

Galileo

Telescope 1609 

 Optics in Siderus Nuncius 1610

Historical remarks: Rutherford, 1911, discovery of atomic nucleus

Slide 6

Basic tools of the trade

Geometry, drawing tools, CAD drafting program (e.g. AutoCad)
