Rolling proposal with reviewing every two months for groups requiring beamtime for a single project.
At present, available only for: POLARIS
Request for beamtime for the use of the POLARIS Cryo-Electron Microscope for Cryo-Electron Microscopy (Single Particle Analysis or Cryo-Electron Tomography).
Rolling proposals are not for samples that have not been characterized yet.
The objective is to improve the resolution of a precise sample.
The rules for the submission of a rolling proposal are:
- the biological sample must be pre-characterised using biochemical experiments,
- grids with this sample must be ready and pre-screened on a 200 kV TEM,
- an atlas of the grids must be available prior to data collection on the 300 kV TEM.
These informations should be provided to the Peer Review Committee for the evaluation of the proposal.
There is currently, no BAG access available for POLARIS.

Submission guide
Submission form is available online on the SUN set, it's divided on 6 tabs for each part of the proposal.
Proposals must be fully written in English and every steps of the proposal has to be saved before continuation.
1/ "General "Tab
This tab contains: the proposal title and keywords which are freely written by the proposal Main Proposer (MP).
The corresponding research area of the proposal has to be selected among a predefinied list of areas.
And the proposal team has to be descibed. Every team member has to be registered on the SUN set. The proposal team can be different of the team performing the experiment at SOLEIL.
2/ "Beamline(s)" Tab
This type of proposal "Rolling proposals" only applies to the CryoEM POLARIS.
No other beamlines can be selected.
It is hightly recommended to get in touch with scientists of POLARIS to check the adequacy between your proposal and POLARIS. This local contact has to be indicated in the proposal form.
The type of techniques has to be selected. The machine operation mode has to be choosen and the needed energy range has to be indicated.
And the number of shifts needed to perform the experiment has to be defined.
3/ "Experiment Requirements/Context/Framework" Tab
You can notify preferred or unacceptable dates to perform your experiment.
Proposals on CryoEM POLARIS are reviewed by Reer-Review Committee 5.
Support laboratories are not available for proposals on CryoEM POLARIS. Sample preparation cannot be done on site at SOLEIL, but in your laboratory.
The proposal context has to be detailled:
- is it a continuation of aprevious proposal? a resubmission of a proposal which has not receive beamtime during a previous call?
And the proposal framework has to be filled:
- is the proposal supported by a contract (industrial, academic, ...)? in collaboration with industrials? a part of a PhD thesis?
4/ "Abstract/Description" Tab
An abstract of the proposal has to be written.
Then, Supporting micro-graphs / Images (Atlas, 2D class, ...) up to 5 have to be uploaded.
Finally, the proposal description has to be described. This description is the biggest part of the committees evaluation: it has to be as precise and concise as possible.
The description has to be written on a Word file donwladable on the SUN set. This file is restricted to 2 pages (figures included).
Under no circumstances the file structure can be modified (titles, spaces, police, ...). Otherwise the file will not be uploadable in the SUN set once completed and converted in PDF.

5/ "Samples" Tab
Samples, substances and ancillary equipments that might be brought at SOLEIL for the experiment have to be declared.
But first you have to read SOLEIL safety requirements for each kind of sample: biologic sample, chemical, radiological, ...
6/ "Results from previous proposals" Tab
If you have already carried out an experiment, please attach here all proposals performed for which you have written an experimental report, submitted in the SUN set and which are related directly or not to the subject of the proposal you are currently editing.
The absence of this report is an eliminatory criteria during committees evaluation if not clearly justified.
