Meteorite Analysis

App note from IXRF Systems

The Murchison meteorite fell in Australia in 1969 near Murchison, Victoria...

A meteorite is the term given to a piece of a comet or asteroid that falls into the Earth's atmosphere and survives to hit the surface Modern classification schemes divide meteorites into groups according to their structure, chemical and isotopic composition and mineralogy.

The Murchison Meteorite belongs to the CM group of carbonaceous chondrites Carbonaceous chondrites are primitive and undifferentiated meteorites that formed in oxygen-rich regions of the early solar system so that most of the metal is not found in its free form but as silicates, oxides, or sulphides

CM chondrites are well known to contain a wealth of complex organic compounds. Like most CM chondrites, it experienced extensive alteration by water-rich fluids on its parent body before falling to Earth.

Cosmochemists reported in January 2020 that the silicon carbide particles in the Murchison meteorite have been determined to be 7 billion years old.

Instrumentation:

Model: Atlas M microXRF

Map (pixels): 1600 x 902

Software: Iridium Ultra Size (mm): 11.40 x 6.42

Voltage: 50 kV

Current: 1000 µA

Point dwell: 130 ms

Atmosphere: vacuum

Filter: open Spot size: 5 µm

Data:

Micro-spot energy dispersive X-ray fluorescence spectroscopy was employed to produce hyperspectral XRF images of the distribution of the primary elements identified in the Murchison meteorite sample. Under the analysis conditions employed, the observable elements were: Mg, Al, Si, S, K, Ca, Ti, V, Cr, Mn, Fe and Ni.

Meteorites are known to contain a significant amount of iron. The elemental map of iron (Figure 2) was set to a thermal scale in the image … to not only show the presence of iron but also the dramatic concentration distribution

The Si-map (Figure 3) shows the silicon from silicon carbide inclusions.

This meteorite is similar to other CM chondrites in that it contains abundant calcium and aluminium rich inclusions. These inclusions can be seen in the elemental map overlay (Figure 4), where calcium is yellow and aluminium is blue.

Figure 1 XRF maps by element
Figure 2 Thermal map of Fe concentration (red is highest)
Figure 3. Silicon carbide map
Figure 4 Inclusions: Ca is yellow and Al is blue

Other elements of research interest were also identified in the meteorite; just a few are shown (Figures 5-7) and are set to a thermal scale to highlight details of areas of higher concentration. The use of a 5 µm spot size allows for incredible detail in the elemental maps

Discussion:

Application of a non-destructive analytical procedure, such as microXRF, to characterise the mineral phases in meteorites solves a key issue in the preservation of these scarce materials Elemental composition analysis was performed using the ATLAS M hyperspectral microXRF imaging spectrometer, affording elemental distribution maps – with 5 µm special resolution – for the meteorite sample Microspot EDXRF expands the abilities of researchers

This analytical technology is ideally suited for the analysis of inorganic species, and offers excellent sensitivity to trace elements (for example, concentrations less than 100 ppm can be detected, depending on the element and sample matrix) Point analysis allows fast identification of mineral species, even when analysing individual grains in a section Hyperspectral imaging provides detailed elemental images, highlighting the distribution of mineral phases and graphically illustrating general structure.

CASE STUDY: MEASURING UP TO NASA’S JAMES WEBB

SPACE TELESCOPE

Measuring optics for space-based optical systems, like the James Webb Space Telescope, comes with a high risk-profile. After all, it’s difficult to get systems into space, and once deployed, it can be very hard to make a repairvisit NASAisunderstandablycarefulnot toleavetheirnextbigopticsprojecttochance, and they have reformulated their testing criteria over the years. NASA senior optical physicist H Philip Stahl has written extensively ontheapproachtheyhavechosen

"Probably the most difficult metrology project in a generation of astronomical optics"

The 18 mirror segments, the secondary mirror, and the tertiary mirror were measured individually and in sets, for surface figure and surface roughness. They were re-measured in cryogenic vacuum conditions. It required a giant helium refrigeration chamber to bring the optics to -240 °C (30K) With pump vibrations surrounding the mirrors, the vibration would be high.

4D Technology was designated primary metrology supplier, providing instruments for several measurements of the optics and the support structure. The selection was in part because of our dynamic metrology technology, and in part because of our willingness to engineer and design to the extremely stringent requirements

The reason TwymanGreen was best

A Twyman-Green configuration of interferometer is capable of retaining light, and expanding to large spherical surfaces.

Measuring concave segmented mirrors

One challenge of measuring a segmented mirror, using interferometry, is that the interferometer has a small tolerance for measuring step discontinuities that is, the difference in Z of one mirror segment to its neighbours in the array The system is prone to vibration, because the focal lengths and the size of the array could not permit the interferometer and the optical array to be coupled together

To ensure NASA could make a measurement that 1) would be vibration immune, 2) could tolerate the step discontinuities, and 3) could capture enough light in a light-absorbing computergenerated hologram measurement, we offered our dynamic interferometry technique in a Twyman-Green interferometer, using twowavelength measurements.

The ability of an interferometer to differentiate step discontinuities is just ¼ of the wavelength used to measure. By using two-wavelength interferometry, the dynamic range increases dramatically by creating a longer functional wavelength The downside is that the time taken to acquire two measurements makes the results more likely to be obscured by vibration. In one proof of concept test, we demonstrated two wavelength acquisitions in less than 100 millionths of a second – effectively making ‘stopaction’ out of any vibration

Learn more about the 4D Technology PhaseCam Models

The 4D PhaseCam line of Twyman-Green dynamic interferometers we first released for this project served in both the ambient and cryochamber tests, and the end-to-end test.

PhaseCam Models

Three models of PhaseCam, a Twyman-Green interferometer with dynamic measurement capabilities

Shorter frequency measurements

The simultaneous phase-shift architecture of the PhaseCam permits rapid measurement of the surface shape for specular reflecting objects

A Tywman-Green interferometer, measuring surface figure, is unable to resolve the microscopic variances and roughness of polish that affect scatter. In space telescopes attempting to image exoplanets, and in X-ray telescopes, ultralow surface roughness and the complex shapes of the optics themselves require tools capable of rapidly measuring surface quality across a very large aperture.

About 4D Technology

4D Technology is the leader in high-resolution surface and wavefront measurements for challenginglocationsandapplications

4D pioneered “dynamic” measurement technology, paving the way for entirely new classes of instruments that change how manufacturers and scientists think about measurement From the world’s premiere astronomical observatories, to optical manufacturing shops, to aircraft flight lines, 4D gages and instruments provide 3D measures accurately, despite vibration and noise that stop other instruments in their tracks

Interferometric measurement of the vibrational characteristics of light-weight mirrors

"We present a technique to characterise and quantitatively measure the vibrational mode shapes and amplitudes of mirrors concurrently with surface figure testing. The technique utilises a fast interferometer that does not introduce any mass loading to the test structure. We present the fundamentals of the technique, discuss several modes of operation, such as resonant and transient response, and analyse the operational limits. The performance of the measurement system is characterised using a small ambient test mirror "

IMAGING VENUS WITH A SCIENTIFIC SWIR CAMERA

More astronomers are looking into the SWIR bands these days. A German researcher, Dr. Sebastian Voltmer, has been looking at the inner planet Venus as a Ring next to the sun and how the crescent is getting bigger. He investigated slight irregularities in the atmospheric layers, as shown in Figure 1.

Figure1:AshortexposuredresultofthecrescentVenusfrom July1,2020

The challenge was to reveal the ground structures of Venus in NIR For surface observations (night side) through the clouds of Venus require a spectral window around 1000 nm

Ninox640IIintelescopeset-up

Tbservations at wavelengths beyond 10 micron are very interesting to observe the lower clouds of Venus through the infrared radiation that escapes from the planet through holes of lower cloud content at an altitude of about 50 km abovethesurface TheNinox640IISWIRcamera was able to reveal the surface and the lower cloudsinoneimage

In late June and early July 2020, the crescent morningstarVenuswasnarrowenoughandthe planet was positioned far enough from the sun. This meant that the sky was dark enough to capture the night side in SWIR The seeing conditions (less turbulence in the atmosphere) beforesunrirsearemuchbetterthanthoseafter sunset On July 1st 2020, Dr Voltmer was able to captureanuniqueimageof CrescentVenusand theinfraredradiation ofthehotplanet

"In my previous images of Venus from May 2020 I only used planetary CCD cameras with NIR sensitivity. It was hard to get any signal of Venus’s surface. But with the cooled Ninox 640 II SWIR camera I got a much better signal-to-noise ratio. With the Ninox 640 II SWIR camera I was able to reveal the surface and the lower clouds in one image"

MATISSE UPDATE

(MATURATION OF INSTRUMENTS FOR SOLAR SYSTEM EXPLORATION)

An international team of astronomers led by Violeta Gámez Rosas (Leiden University) has observed a supermassive black hole hidden in a ring of dust. This discovery fits the idea that the so-called active centres of galaxies are much more similar than observations show, because the viewing angle from Earth causes distortions The research was done with the MATISSE instrument, co-developed in the Netherlands, which combines infrared light from four European Very Large Telescopes (VLT) in Chile

MATISSE is the acronym for Multi AperTure mid-Infrared SpectroScopic Experiment. MATISSE not only couples the ls between light from the VLT, but also

Netherlands Research School for Astronomy (NOVA) built all the lenses and mirrors in the cooled part of MATISSE together with the Dutch space industry. The Netherlands had gained experience while developing its forerunner MIDI, which could link two telescopes instead of four.

The heart where the beams of the four VLT telescopes converge, consists of two aluminium boxes that are almost a meter in size These boxes are filled to the brim with hundreds of optical components, dozens of sensors and dozens of tiny motors. Most of the components work with nanometer precision or even higher.

Credit: ESO/M Kornmesser and L Calçada analyses it. MATISSE was created specifically for infrared light with wavelength 3 micrometers and 13 micrometers Infrared light is also created when something gives off heat. Therefore, MATISSE is cooled to minus 241 degrees Celsius so the instrument itself does not interfere with the measurements. Nanometer precision.

This illustration shows what the core of Messier 77 might look like. As other active galactic nuclei, the central region of Messier 77 is powered by a black hole that is surrounded by a thin accretion disc, which itself is surrounded by a thick ring or torus of gas and dust In the case of Messier 77, this thick ring completely obscures our view of the supermassive black hole This active galactic nucleus is also believed to have jets, as well as dusty winds, that flow out of the region around the black hole perpendicularly to the accretion disc around it.
