On Proposal Submission

We invite users and collaborators to discuss their proposals with the beamline local contacts in advance before the submission deadline. This may be crucial for a careful assessment of the experiment feasibility and may result in an improvement of the proposal.  Please read carefully guidelines for proposal rating-submission.

Call for proposals

Call for proposals

The deadline for proposal submission for beamtime allocation is to be announced

Experiment feasibility

Read carefully the information on the Spectromictroscopy web pages, especially that concerning the beamline energy range, resolution, and the microscope lateral resolution. 

Sample suitability

It is very important to keep in mind that not all samples are suitable. Samples must be conductive and resistant to radiation damage. 

Arranging a feasibility test

Sometimes it is difficult to predict whether an experiment will work or not. When doubts arise about the samples or the proposed measurements are too close to the microscope resolution limit, we will try to arrange a test for you given enough beamtime available etc.

List of available stuff

Preparation chamber (zipped file with PDF designes) has LEED&AUGER, Ar+ sputter gun (0.5-5 kV), Omicron evaporator for 3 sources, gas line for 2 gases. Sample manipulator of preparation chamber can be cooled down to -100 0C and heated up to 300 0C, if you need higher temperatures we have heater up to >2000 0C. Also we have  UHV dimond scraper, cleavage posts and silver epoxy for UHV, Omicron sample holders from copper, tantalum and molibdenum. Additionally we can also make Louer measurements of your samples for orienting them on the sample holder.. If you need more or something else please contact us and we will check if we have it.

Scheduling accepted proposals

The beamline coordinator takes care of contacting all of the users whose proposals have been accepted, following the rank indicated by the Review Panel. We try to arrange the beamtime calendar keeping into account the experiment requirements and your specific needs.

Sending us your instrumentation

During the scheduling of the various proposals, we carefully check with you whether we have all the necessary equipment for  experiments. If something is missing, we make specific agreements so that you send us what is needed in time for the experiments. If you prefer to bring the instrumentation you need to install in the preparation chamber  with you, note that we need at least 36 hours for the chamber to be ready to use and plan your arrival accordingly.

Preparation of the experiments

In the case of complex experiments, e.g. experiments that require lengthy preparation, agreements can be made for you to begin to work a few days earlier than the official beginning of the beamtime. This might be useful when in-situ sample preparation is needed, or for the calibration of evaporators, or if complex instrumentation needs to be installed.  All of this is discussed with the beamline coordinator at the sutable time in advance.

Important note concerning funding

Funding agencies normally refund expenses in the time interval one day prior and after the beamtime. Thus, in the case you arrive earlier, your expenses ARE NOT COVERED. We invite you to check this with the Elettra User Office.

Before your arrival

The user office webpages offer you advice on several topics regarding your staying at Elettra, including accommodation, car rental and how to reach the Elettra site.

Fill the Access Request in advance!

Most importantly, don't forget to fill in the Access Request from. Timing for the submission of the Access Request varies according to Users Categories: General Users, Research Team Members and Collaborators must submit their Access Form at least two weeks before the experiment. Italian Users must submit their Request at least one month before the experiment.

Contact us

Don't forget to contact us, so that we can arrange an appointment to meet at the beamline!

Data storage and data type

All the data are saved, even the measurements you started and interrupted because there is something wrong with the settings will have corresponding file. Each day data are saved in appropriate folder and the filnames are SM"N""date"_"number". hdf5 where N=L for focusing line scans, I for images, P for spectra and polar or azimuthal scans.
The data format is hdf5.

Data processing software

To visualize and process HDF data collected in our microscope, we use WaveMetrics Igor Pro 5.05A or higher. However most of the new rutines works with latest version of Igor Pro 6. The scripts should work as well in the higher versions of Igor Pro, the earlier versions are not supported. In the most cases the scripts are run in Windows, so the instructions here are written basing on the Windows esperience mostly. But since Igor Pro 5.05A exists also for Mac, you can use.

Scripts installation

You will need to install some scripts to work with the data. First, you need to install Wavemetrics HDF5 library. This is some general library used to handle HDF, version 5 data in Igor, supplied with simple Igor browser for the HDF5 data. The library files are included in the Igor Pro package, all you need is to perform simple activation procedure as described below:

To install HDF5 library with HDF5 browser:

  1. Make an alias (Mac OS X ) or shortcut (Windows ) for the following file: Igor Pro Folder\More Extensions\File Loaders\HDF5.xop. Move the alias or shortcut into the "Igor Pro Folder\Igor Extensions" folder.
  2. Make an alias (Mac OS X ) or shortcut (Windows ) for the following file: Igor Pro Folder\WaveMetrics Procedures\File Input Output\HDF5 Browser.ipf. Move the alias or shortcut into the "Igor Pro Folder\Igor Procedures" folder. This activates Igor procedures that implement an HDF5 browser and add a "New HDF5 Browser" menu item in the Data->Load Waves menu.
  3. Restart Igor Pro.

When the HDF5 library is installed, you can install our scripts. For the installation, please follow the directions below.

To install scripts to process your data for Igor 5n.

  1. Download archive containg 6 files with scripts and Igor template file.
  2. Create a new folder on your hard drive, like subfolder \User Procedures\SPM of Igor Pro folder. U
  3. Unzip files from archive with "ipf" extension into this folder, and place unzipped Load_SPEM_5.pxt template to some convinient place like your desktop.
  4. Double-click on the Load_SPEM_5.pxt, Igor will start loading and will probably ask you about the location of the file. Point it to the directory where you have unzipped the "ipf" files. When Igor will load, you will have a new menu named "SPEM".
  5. Save the Igor file before start working.
For Igor 6n and 7n the instructions are below

Download and unzip the macros file  (igor6) or file (igor7)

and follow instructions below:
Assuming Igor Folder is:

C:\Program Files\Igor Pro Folder or C:\Program Files\WaveMetrics\Igor Pro Folder or whatever location you have further reffered as
\Igor Pro Folder and HDF5 browser is already installed

The example is given for Windows XP,
where Igor is located at C:\Program Files\Igor Pro Folder

1. Goto parent directory
C:\Program Files\Igor Pro Folder
where Igor is located. Copy into appropriate subfloders

\User Procedures\Menus\
\User Procedures\\SpecMicElettra\Load_SPEM_5\

2. Add the menu launch link
make a link to the file:
\Igor Pro Folder\User Procedures\Menus\SPM_LoadMenus.ipf
and place/overwrite existing one in:
\Igor Pro Folder\Igor Procedures\SPM_LoadMenus.ipf.lnk

3. Launch Igor
In the main menu click on:
Data->Load Waves->Load SPM_Data
See SPEM submenu in main menu line

For Igor 8 n and 9n the instructions are below
             Check if HDF utilities are abilitated already as should be for Igor 9, otherwise abilitate them as described above (install HDF5 library)

            1. Download and unzip the macros files
            2. Copy them to User Documents folder WaveMetrics\Igor Pro 9 User Files\User Procedures
             as for PC
             C:\Users\Root\Documents\WaveMetrics\Igor Pro 9 User Files\User Procedures

             3. Create an alyas to SPEM_LoadMenus (in Menus folder)
            and place it in C:\Users\Root\Documents\WaveMetrics\Igor Pro 9 User Files\Igor Procedures
