Digital Sweep

The Telemark electron beam source (ebeam gun) digital XY sweep is the latest in beam control technology from Telemark. It affords precise beam control and high repeatability for vapor cloud uniformity. This unit comes with a handheld joystick and replaces the older analog style sweep units. A color LCD touch screen shows real time display of source pocket.

The Digital Programmable Sweep controls the pinpoint location of the EB Source beam spot. Patterns are viewable from the LCD screen and can be edited to change size, frequency, rotation, profile and location.

Features

5 Preset shapes (triangular, sinusoidal, collapsible circle, rotatable line, point)
User definable oscillation frequency, amplitude, rotational speed, circular pattern collapse size
Memory for eight user definable patterns
High repeatability for consistent yields and material usage
Binary coded or direct line remote pattern select and feedback
Intuitive – short learning curve for operators and engineers
Tight beam control and uniform energy distribution for dielectric and subliming materials
Stable single spot for evaporation of metals
Excellent for processes requiring repeatable vapor cloud distribution
Replace older style analog sweeps

PROGRAMABLE SWEEP ADDITIONAL FEATURES

Stores 32 user shapes and 32 patterns that are remotely selectable
User may edit any step in a shape without rewriting the program
Unit adjusts output to match deflection characteristics and magnetic distortion of each source, so displayed shape mirrors actual shape in the chamber
Compatible with all transverse beam sources, featuring offset and an interlock for sources requiring coil bias for pocket center

Programmable Sweep Profile

Some shapes have a profile variable. Positive values will spend more time on the edge of the pattern, negative values will spend more time at the center of the pattern. Some materials and patterns can benefit from power profiling by creating a more constant beam energy density as the beam sweeps across the area of the pocket.

Programmable Sweep Profile

Sweep Distortion Adjust

Both the Digital Sweep and the Programmable Sweep have 9 points to define the size of the pocket. This gives you control over the distortion adjustment to compensate for the physical properties of the e-beam source magnetics. This feature may be of interest if the circular sweep setup pattern exhibits any non-circular path aberrations.
