Other Features
The analyser package includes:
▪ EA15-HP1 150 mm hemispherical energy analyser
▪ RUDI-EA2 high stable and low noise electronics
▪ SPECTRIUM acquisition and analyser control software for Windows OS computer system.
Additional information
EA15 hemispherical energy analyser can be controlled directly by LabVIEW programming environment.
Note:
The use of a mu-metal analysis vacuum chamber or an inner mu-metal shielded chamber in combination with EA15 analyser is recommended in order to minimise influence of external magnetic fields and to maximize performance of the analyser.

Software
Research Unit Digital Instrument RUDI-EA2 Software
The SPECTRIUM 2.0 is based on the novel developments in techniques and signal processing. The user can define the range of voltage (low and high pass) without any manual changes from the level software. The PES and ISS mode can be set from the SPECTRIUM software. The SPECTRIUM consists of a spectrometer control panel for lens mode, energy settings, step time etc. Moreover data acquisition in the 1D, 2D and 3D is included. The SPECTRIUM file format for sequence and region scans can be exported to many formats and the most of the processing software as CASA XPS, IGOR, ORIGIN opens SPECTRIUM files.
Interactive scan control
The SPECTRIUM software design has been optimised for more efficient workflow, resulting in a streamlined and simpler design. The control module is interactive and dynamic allowing adaptation of parameters to customer’s needs.
All scan parameters can be adjusted on-the-fly without delay during scanning, and it is possible to zoom, navigate and paste scanned spectra to the background for reference. Any of the parameters can be displayed in multiple windows. The user has online access to the CCD detector to configurate channels.
Experimental Automation Modules
In most complex measurement Spectrium with RAPID SE offers a fully automatisation of the measurement processes. User can define any configuration for the entire analysis system. The stored data includes all experimental parameters and devices with all logs and notes.
Advanced 2D and 3D spectroscopy
Advanced spectroscopy module allows for experiments at a point, along a one of direction, or a maps mode.
High quality spectra
User can use the SPECTRIUM software for many experimental techniques for any research. It can measure high quality spectra.
Integration with TANGO and other control systems
