Description

The Planetary Emissivity Laboratory (PEL) is a special sub-session of the Planetary Spectroscopy Laboratory (PSL) of the DLR in Berlin, devoted to emissivity measurements in of samples from low/moderate to high temperature (temperature range from 300 to above 1000 Kelvin).
Emissivity measurements are recorded by using an external emissivity chamber (DLR-custom-designed) attached to a Bruker Vertex80V FTIR from the visible to the far-IR (from 0.4 to 150 µm), with a high SNR. Induction system is used to heat up stainless steel cups containing the sample.
Currently an In-Xitu’s Terra portable X-Ray Diffraction (XRD), X-Ray Fluorescence (XRF) instrument is available at PEL for sample characterization.

Instruments

Planetary Simulation Chamber
X-Ray Fluorescence spectrometer (XRF: Primary X-Rays are used to excite (fluoresce) X-rays in the specimen. A fused disc or pressed pellet is used for the determination of major element concentrations or trace element abundances in a bulk specimen. The X-ray detector utilizes a set of diffracting crystals specially positioned to detect one characteristic X-ray at-a-time. This sequential measurement of X-rays is termed Wavelength Dispersive Spectroscopy (WDS).

Measurement method using diffraction of X-radiation to obtain the spatial arrangement of atoms in a crystalline sample. Note 1: Bragg reflection follows nl = 2 d sin q, where l is the X-Ray wavelength, d is the spacing between atomic planes, and q is the angle of diffraction. Note 2: Copper K-a radiation (l = 0.15406 nm, E = 8.04 keV) is typically used for routine XRD.
