LEED and
LEED-AES |
Low Energy Electron Diffraction (LEED)
is one of the most powerful methods for the determination of
surface structure. Analysis of LEED patterns and intensities
provides the size and shape of the surface unit cell, the degree
of order, and detailed atomic structure with a precision of
the order of picometres. |
| EELS |
A new electrostatic dispersive device with controlled
angular aberrations is a key element of this instrument. An
energy loss spectrometer("Delta 0.5" UREELS) built with such
dispersive elements has a theoretical resolution limit of 0.3
meV, and an experimentally achieved resolution of 0.5meV. |
Energy Analysers,
X-Ray Sources |
SPECS has a long history of production of high
performance "add-on" electron energy analyzers for special purpose
UHV analytical systems, of which the EA 10 and EA 200
series provide established benchmarks in their class.
Now with the PHOIBOS analyzer, SPECS presents a new generation
of hemispherical analyzers aiming to set the standard for these
devices. New approaches and technical solutions led to a system
that combines excellent performance with highest reliability
for the largest possible variety of experimental conditions. |
UV Sources and
High Density UV Source |
A long established speciality of SPECS, the UPS
sources and accessories again set the standard for performance
and ease of use. |
SNMS and
SIMS Systems. |
Both modules (for add-on to existing instruments)
and complete systems are available, for SIMS, SIMS/RGA and Thermal
Desorption Analysis. Secondary Neutral Mass Spectrometry (SNMS)
is available from the SSM 200 package |
Flood Guns and
other Components |
SPECS offers a wide range of high and low energy,
focussed and broad beam electron and ion sources for general
and specific surface analytical applications. |
UHV Surface Analysis
Systems |
SPECS offers a full range of complete instruments
for quality control, product engineering, environmental studies
and routine tasks in surface analysis, as well as high performance
research configurations. All systems feature compact, modular
design and flexibility, and are easy to operate with fully computerized
control of the vacuum system, sample handling, data aquisition
and data processing (via predefined routines, where appropriate) |
