Your controller is a computer that performs the following functions:
•
Provides an interface between you and the analysis instrument.
•
Enables you to set up experiments and enter necessary information.
•
Stores experimental data.
•
Allows data analysis of results.
DXF System Components
A DXF system has three major components: the DXF Pulse Source module, the Environmental Module
with Detector Assembly, and the controller.
Pulse Source Module
The Discovery Xenon Flash (DXF) covers the most commonly needed cryogenic to 200°C temperatures
with a range of Environmental Modules, and employs a High Speed Xenon-Pulse Delivery Source
(HSXD). The reflective optic configuration effectively harnesses the power of a Xenon flash tube, and,
with the aid of proprietary wave guides, delivers it to the sample inside the Environmental Module. The
DXF produces a maximum pulse width of 400 to 600
μ
s
while uniformly concentrating sufficient power
from the flash source directly on the entire face of the sample. This optimized energy gathering scheme
and the broad light spectrum allows samples as large as 25 mm in diameter to be illuminated with suffi-
cient energy.

INTERNAL INTERLOCK 1
This internal interlock checks to make sure the metal covers
are in place around the flashlamp assembly. When the covers
are closed the INTERNAL INTERLOCK 1 LED changes
from red to green. When all interlocks are green, the flash-
lamp is safe to fire.
