Software and data format

Acquisition software at GILDA

The beamline is run using VMEs in the experimental hutches linked to Macintoshes and PCs in the control box via ethernet. Programs are developped following a server-client philosophy. Servers run on the VMEs in the experimental hutches managing very general, low-level operations and can be accessed from clients running from any machine. In most cases experiment clients are developped in LabView ambient on a Macintosh computer and can be easily adapted to user needs for non-standard data collections. Instructions for the standard acquisition programs and data structure are given in the Beamline Manual .

Data analysis

Preliminary data analysis can be performed on the beamline. A Macintosh, a PC (with Windows 98) and a LINUX machine are available for users. Software licenced to GILDA includes programs for XAS analysis ( FEFF, UWXAFS, GNXAS, EXAFS pour le Mac, XAFS, EDA ) for image processing Fit2D , powder diffraction analysis (GSAS).

Data handling

Data can be collected by the user with 3.5" diskettes (DOS and MacOS formats are supported), 250 Mb ZIP disks (only Mac ) or directly sent home via FTP. For huge data volumes (it is the case of diffraction data with an Image PLate detector) a CD-ROM writer is available on the beamline.

Connecting your laptop

Some spare IP numbers are available on the beamline subnet for connecting your laptop computer to the network. The details of the configuration depend on the machine you use (Mac, PC, LINUX, ...) here we recall some general points:

IP Number	160.103.128.50 to 53
Subnet mask	255.255.255.0
Gateway	160.103.128.99
DNS	160.103.6.12
Domain name	esrf.fr
