Estonian Scientific Computing Infrastructure (ETAIS)

RI description

The Estonian Scientific Computing Infrastructure (ETAIS) was established in 2011 to increase the competitiveness of Estonian R&D in computing and data-intensive fields through the provision of a modern computing infrastructure. The common infrastructure for compute clusters, storage, and support allows researchers to collaborate together in projects on a local level as well as on an international level. ETAIS is the distributed infrastructure which is managed by a consortia of four national organisations: the University of Tartu, Tallinn University of Technology, the National Institute of Chemical Biology and Physics, the Information Technology Foundation for Education (formerly the Estonian Education and Research Network (EENet)).

Nanomaterials - Research and Applications (NAMUR)

RI description

NAMUR is a multidisciplinary decentralised material research infrastructure in Estonia with the primary goal of:
1) providing worldwide top level IR for material characterisation at the nano and sub-nanometre scale;
2) making Estonia visible as a potential source of high level knowledge in the field of nano-scale material science;
3) increasing the knowledge involved in, and providing an educational platform for, nanoscale material science in Estonia.

The RI is composed of three separate facilities: a High Resolution Transmission Electron microscope (HR-TEM); the Time of Flight secondary Ion Mass Spectrometer (ToF-SIMS); and the High Resolution Scanning Electron Microscope equipped material characterisation complex (MAT-SEM). The RI is jointly owned by two Estonian universities: Tartu University and Tallinn Technical University.

RI research services

The HR-TEM facility provides the ability to characterise and visualise both material composition and structural defects at a sub-nanometre scale.
The ToF-SIMS facility provides a service for characterising the chemical composition of materials both at high lateral levels of accuracy and with mass selectivity.
The MAT-SEM facility provides a complex service for growing thin film materials with a laser ablation device, the NANO-PLD-1000, and measuring mass and structural properties with a crystal resonance mass detector and a high resolution  scanning electron microscope (down to 0.6nm). The facility is supported with full-time operator support.

Equipment at the RI

ToF-SIMS: the Time of Flight Secondary Ion Spectrometer is used for measuring the chemical element composition of material with high spatial accuracy.
HR-TEM: the High Resolution Transmission Electron Microscope. Apparatus for nanoscale imaging and the element analysis of specially-prepared material samples with sub-nanometre resolution for investigating the atom-level properties of materials.
MAT-SEM: a high resolution Scanning Electron Microscope-equipped materials growth and characterisation setup.
