ALS beamline 12.3.2 identified the other minerals in the Roman samples.
Two projects that have definitely been guaranteed funding are
new beamlines for the Diamond synchrotron near Oxford and the new UK Centre for Medical Research and Innovation (UKCMRI), due to open in London in 2015.
The diamond synchrotron facility offers, through Instruct, the IO3 tuneable X-ray
beamline for macromolecular crystallography which uses automated sample changing and plate technology.
Small - angle neutron scattering data obtained
on beamline D11 at the ILL was crucially used to prove the internal structure of these clusters.
A monochromatic X-Ray beam was used at
beamline ID19 at the European Synchrotron Radiation Facility.
As part of their study, Jackson and her collaborators at UC Berkeley used ALS
beamline 12.3.2 to make X-ray micro-diffraction measurements of slices of the Roman mortar that were only about 0.3 millimeters thick.
The PSCM facilitates a deeper exploitation of state - of - the - art neutron instruments and
synchrotron beamlines in combination with on - site specialised sample preparation and characterisation facilities.

«It allows you to see all of this interplay in chemistry,» said Michael Martin, a senior staff scientist in charge of
infrared beamlines at the ALS.
Another upgrade that may be useful to the U.S. laser program is the addition of a
second beamline at BELLA, Leemans says.
X-probe creates close interdisciplinary collaboration between structural biologists, physical chemists,
beamline engineers, software developers, and industrial partners.
The integrated HPCAT facility has established four
operating beamlines in nine hutches An array of novel X-ray diffraction — imaging at tiny scales — and spectroscopic techniques to reveal chemistry, has been integrated with high pressure and extreme temperature instrumentation.
Accelerator Scientist Yan Wang recorded and provided insight into machine performance, and Yves Roblin was the Accelerator Physics Experimental Liaison for the Hall
A beamline.
The Australian Synchrotron's X-ray Fluorescence
Microscopy beamline clearly showed researchers how zinc migrates to the center of the grain during this optimal parboiling approach, making the milled white rice more nutritious.
Researchers used the 12 - ID - B and 32 -
ID beamlines at the Advanced Photon Source, also a DOE Office of Science User Facility, to take X-ray scattering measurements, as well as transmission X-ray microscopy nano - computed tomography of the samples, scanning electron microscopy and transmission electron microscopy.
The synchrotron has no guaranteed funding beyond June 2012, putting plans for
more beamlines on hold.
For this research, the team used the Center for Nanoscale Materials as well
as beamline 12 - ID - C of the Advanced Photon Source, both DOE Office of Science User Facilities.
Using their latest laboratory,
beamline I23, an ultra-high-resolution 3D model of the PETase enzyme was generated in exquisite detail.

biology beamlines where the experiments were carried out.
Nobumichi Tamura, an ALS staff scientist, said the X-ray
beamline where the Roman concrete samples were studied can produce beams focused to about 1 micron, or 1 thousandth of an inch, «which is useful for identifying each mineral species and mapping their distribution.»
The team around Bösenberg, which also includes researchers from the University of Giessen, from the University of Hamburg and from Australia's national science agency CSIRO, studied the negative electrodes of this LiNi0.5 Mn1.5 O4 compound at PETRA III's X-ray
microfocus beamline P06.
ORNL's Steven Dajnowicz (left) and Andrey Kovalevsky prepared a sample to begin neutron structural analysis of a vitamin B6 - dependent protein using the
IMAGINE beamline at ORNL's High Flux Isotope Reactor.
Using the MaNDi instrument,
SNS beamline 11B, they hope to better understand how bacteria containing enzymes called beta - lactamases resist the beta - lactam class of antibiotics.
The program was previously developed at the
SIBYLS beamline (12.3.1) of the Advanced Light Source, Berkeley, CA.
The Institute is now strongly involved in design of two of the instruments that will be installed at ESS and with a
test beamline in JEEP II.
On
beamline ID15, scientists can use imaging, to see how cracks grow, and diffraction, which tells them about the local stresses that the cracks grow under.
These X-ray flashes are then distributed to initially three
beamlines with six experiment stations.
In situ high pressure gas flow experiments performed at X-Ray Science
Division beamline 17 - BM at the APS using the X-ray powder diffraction technique at low temperatures managed to elucidate the structure of two different metal - organic frameworks with neon gas captured within the materials.
Integration of the results from the
various beamlines revealed the minerals» potential applications for high - performance concretes, including the encapsulation of hazardous wastes.
High - pressure x-ray diffraction experiments at ALS
beamline 12.2.2 measured its mechanical properties and, for the first time, clarified the role of aluminum in its crystal lattice.
«We were deeply concerned about the development of the science and investment case [for new
beamlines],» says Gallagher.
Brookhaven scientists are pictured at NSLS -
II beamline 8 - ID, where they used ultra-bright x-ray light to «see» the chemical complexity of a new catalytic material.
The synchrotron, he says, is «doing brilliantly» in terms of generating scientific publications and maintaining high -
quality beamlines.
Synchrotron - light for Experimental Science and Applications in the Middle East (SESAME), an $ 80 million synchrotron lab in Allan, Jordan, announced this week its first call for research that will be conducted on two
beamlines expected to switch on this autumn.
Last month in Cairo, officials from Jordan promised to fund a building for the accelerator and its
upgraded beamlines at a site at Al - Balqa» Applied University outside Amman.
«I wanted to use a submicron X-ray beam, so I asked colleague Kenneth Evans - Lutterodt to perform an experiment on the
microdiffraction beamline at Brookhaven National Laboratory,» she added.
They therefore fabricated a series of organic thin films with increasingly heavy levels of doping and investigated these samples using X-ray diffraction techniques at the KMC - 2
beamline managed by Dr. Daniel Toebbens.
This large anisotropy leads to a remarkable magnetic moment, which has been determined with synchrotron - based measurements at the
X-Treme beamline at the Swiss Light Source.
«We have shown that by interfacing a topological insulator, bismuth selenide, with a high temperature superconductor, BSCCO (bismuth strontium calcium copper oxide), it is possible to induce superconductivity in the topological surface state,» says Alexei Fedorov, a staff scientist for ALS
beamline 12.0.1, where the induced high temperature superconductivity of the topological insulator heterostructure was confirmed.
