Proposal Writing for BMM | ||
======================== | ||
|
||
XAS Experiments | ||
--------------- | ||
|
||
`Bruce Ravel <mailto:[email protected]>`__ supports XAS experiments at | ||
BMM. If you have any questions about the capabilities of the beamline | ||
for XAS experiments or questions about an XAS proposal, contact him. | ||
|
||
When writing a proposal for beamtime, it is important to remember that | ||
you are justifying your *need for beamtime*. This, then, is of a | ||
different sort than a funding proposal. While justifying the | ||
importance of your science is certainly a part of the beamtime | ||
proposal, the main purpose is to tell the review panel and the | ||
beamline staff how you intend to use your beamtime effectively. | ||
|
||
+ Explicitly state how many samples you intend to bring. | ||
+ Explicitly state what the differences are between the samples. | ||
+ If you will be measuring under *in situ* conditions |nd| | ||
temperature, electrochemical potential, gas flow, or anything else | ||
|nd| state what those conditions are. | ||
+ If you are measuring a dopant, state the concentration of the dopant. | ||
+ If you are measuring a low concentration sample |nd| for example the | ||
amount of arsenic in a natural sample |nd| provide an estimate of | ||
the concentration. Even better, do elemental analysis of an aloquat | ||
in the electron microscope or with ICP. | ||
+ If you are measuring a thin film sample, state the thickness of the | ||
sample and the areal dimensions of the sample. | ||
+ If you have a matrix of sample conditions |nd| for example a range | ||
of dopants, a range of absorption edges, and a range of annealing | ||
conditions |nd| do the math. Tell the reader how many XAS | ||
emasurements are required. | ||
+ Make sensible estimates about your time requirements. Be prepared | ||
to prioritize your samples if you are unable to get the full time | ||
your request. | ||
|
||
.. admonition:: Ask questions early! | ||
:class: note | ||
|
||
If you have any questions about beamline capabilities, measurement | ||
times, experimental feasibility, or any other issue pertinent to | ||
your beamtime proposal, contact the beamline staff well before the | ||
proposal deadline. | ||
|
||
XRD Experiments | ||
--------------- | ||
|
||
`Vesna Stanic <mailto:[email protected]>`__ and `Jean Jordan-Sweet | ||
<[email protected]>`__ support scattering experiments at BMM. If you have | ||
any questions about the capabilities of the beamline for scattering | ||
experiments or questions about a scattering proposal, contact them. | ||
|
||
BMM is equipped with a 6-circle psi goniometer, a strip detector, a | ||
small area detector, and point detectors. This installation supports | ||
diffraction in the Bragg geometry and is optimized for reflectivity, | ||
pole figures, truncation rods, and other surface scattering | ||
measurements. | ||
|
||
If you are looking for any | ||
scattering experiment in the Laue geometry, consider applying for time | ||
at `QAS <https://www.bnl.gov/nsls2/beamlines/beamline.php?r=7-BM>`__, | ||
`PDF <https://www.bnl.gov/nsls2/beamlines/beamline.php?r=28-ID-1>`__, | ||
or `XPD | ||
<https://www.bnl.gov/nsls2/beamlines/beamline.php?r=28-ID-2>`__. | ||
|
||
To be very clear, `pair distribution function analysis | ||
<https://doi.org/10.1098/rsta.2018.0413>`__ is not available at BMM. | ||
Any proposal requesting PDF analysis will be denied at feasibility | ||
review. | ||

Multi-modal Experiments | ||
----------------------- | ||
|
||
From time to time, users want to do both spectroscopy and scattering | ||
at BMM. NSLS-II allows a user to request multiple measurement types | ||
in a single proposal. This is called a "multi-modal" experiment. | ||
|
||
However, asking for XAS and XRD in a single proposal at BMM is an | ||
edge-case for the NSLS-II multi-modal program. | ||
|
||
It turns out that there is no way to request a multi-modal proposal | ||
where *different* measurement techniques are performed at the *same* | ||
beamline. Thus, there is no way to send both parts of the multi-modal | ||
proposal to the relevant proposal review panels. | ||
|
||
As a result, if you wish to request both spectroscopy and scattering | ||
at BMM, you need to write **two proposals**. That is the only way to | ||
route your work through the review system correctly. | ||
|
||
.. caution:: | ||
|
||
A proposal requesting both XAS and XRD at BMM will be denied at | ||
feasibility and a link to this web page with be given as the | ||
reason. |
