Enterprise resource planning (ERP) software is often criticized for being complex and difficult to use—which puts up a barrier to receiving potential benefits. Systems with integrated search functionality and Web-like interfaces can make ERP solutions easier to use. Learn how to evaluate ERP software for its usability, so you can avoid investing in platforms that aren’t evolved toward usable and efficient interfaces. Read More

The IVR Playbook: Your Guide to Choosing, Designing, Developing, and Delivering an IVR Platform that Ensures a Great Customer Experience

At its core, interactive voice response (IVR) technology allows a computer to interact with a customer through the use of voice and touch-tone telephone keypad inputs. Looked at closely from a business perspective, IVR can be a huge part of an enterprise’s customer experience.

This IVR playbook looks at things to keep in mind when considering investing in a new or upgraded IVR system. It looks at who uses IVR technology and what could indicate that it’s time to make a change to your IVR... Read More

Designing a Converging-beam Electron Gun and Focusing Solenoid

A frequent electron gun design goal is to produce a converging beam that matches to a focusing solenoid. This white paper describes a case study for a system to generate a narrow electron beam at high-current density and to transport it over a distance exceeding 8.0 cm for experiments on high- frequency microwave generation. Read More

Improved Trak Models for Beam-generated Magnetic Fields

This paper describes new methods in the Trak charged-particle optics code to find the self-consistent, beam-generated magnetic fields of high-current beams. The modifications are helpful for general work with relativistic electron beams. They are critical for simulations of high-power microwave devices like the relativistic magnetron and the magnetically-insulated line oscillator. Read More
