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.

.. 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.


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.
