Introduction

The intention of this Learning Center Section is to provide the reader with the tools and guides to determine which Electron Gun Beam System would provide the specifications and functions needed for your application.  It may be helpful if the reader first goes through the Electron Gun Beam System Tutorial to become familiar with the basic principles and terminology.

The first section below, the Electron Gun Beam Selection Guide, provides a roadmap to finding the best system for your application in our portfolio of Electron Gun Beam Systems.  It guides the user by answering a sequence of questions that include application, major system specifications, and then determining other necessary features and options.

The Electron Gun Beam System Application Table Matrix section allows the reader who already knows what their specific application and specifications are to efficiently  look through our selection of electron gun beam systems.

The next section of Electron Gun Beam System Energy Comparison Tables divides the our Electron Gun Beam System selections into High, Medium and Lower energy selections and then provide other associated information such as beam current ranges, spot size ranges, and working distance to then quickly determine which system and features would be optimal for your application.

In the final section, Electron Gun Beam Systems Cathodes / Electron Emitters we provide a summary of the characteristic of cathodes that are available for use in our Electron Gun Beam System. Please note that several factors determine which cathodes are available in a particular system (not all cathodes are available for all systems).

If your application is significantly different or would be a custom application using our Electron Gun Beam Systems and Optics, please reach out to Kimball Physics to speak directly with our Physicists and/or Engineers to see what may be possible with our advanced technology.

Please download our Electron Beam System Selection Guide:  Summary Form PDF document to summarize your research looking for the Electron Gun Beam System for your application.

Electron Gun Beam System Selection Guide 

The Electron Gun Beam Selection Guide, provides a flow path to finding the best system in our portfolio of Electron Gun Beam Systems.  It provides a “flow path” to answering a sequence of questions that include Application, major system specifications, and then determining other necessary features and options.

Procedure

  1. Enlarge (zoom) the window to make the large amount of information more readable (Adjust lower right to about 100 %).  You can navigate around the map with the scrolls bars along the bottom and side of the window. If you want the window full page, click the icon with the lower right menu area (looks like a box with an upward pointing arrow. The mind map in its own browser window tab.
  2. Start at the top of the open nodes.  The tree of nodes can be opened and closed to expand or contract the information (look for the icon at the end of the text node).  Links are typically available at the end of the nodal path (within the node- upper right arrow) to move to more specific and detailed information.

Electron Gun Beam Systems Organized by Electron Energy (keV)

Kimball Physics products have evolved into a broad range of electron beam systems that we arbitrarily characterized as low energy (up to 5 keV), medium (up to 30 keV) and high (up to 100 keV) energy systems. Many of the systems were born from custom projects, which still is a large portion of our focus.

Low Energy Systems

Low Energy Systems, with energy ranges from 1 eV up to  5 keV, currents ranging from 1 nA to 2 mA, and spot sizes from 0.5 mm  to 100 mm are available.

The tables below provide comparison of the Electron Gun System specifications and the typical Applications and Features for each Low Energy Electron Gun System.

Low Energy Electron Gun Systems (<5 keV)

 

Medium Energy Systems

Medium Energy Systems, with energy ranges from 100 eV up to  30 keV, currents ranging from 1 nA to 5 mA, and spot sizes of 60 microns to 450 mm are available.

The tables below provide comparison of the Electron Gun System specifications and the typical Applications and Features for each Medium Energy Electron Gun System.

Medium Energy Electron Gun Systems (<30 keV)

 

High Energy Systems

High Energy Systems, with energy ranges from 1 keV up to  100 keV, currents ranging from 1 nA to 2 mA, and spot sizes from 50 micron  to 500 mm are available.

The tables below provide comparison of the Electron Gun System specifications and the typical Applications and Features for each High Energy Electron Gun System.

High Energy Electron Gun Systems (< 100 keV)

Electron Gun Beam Systems Cathodes / Electron Emitters

Kimball Physics designs and manufactures a broad range of high performance electron emitters to meet the diverse needs of our customers. Designed for high brightness, long life, or rugged reliability, these emitters  are used in Kimball Physics electron guns  and the high performance  instruments and tools of our customers. Cathodes/emitters are available as both standard products and custom designs, and applications include electron microscopy, lithography, x-ray generation, free electron lasers, electron accelerators, and more.

Not all cathodes are available for all Electron Gun Beam Systems. The selection of the cathode is based on several parameters such as expected vacuum conditions, energy spread, emission current and density, and brightness requirements. The chart below provides insight into the features of each of the cathode types available at Kimball Physics for use in our Electron Gun Beam Systems.
