The cyclotron Laboratory has been in service since 1985, and it is still the highest-energy particle accelerator in Hungary. The MGC-20E cyclotron produces accelerated particle beams for both fundamental and applied research, as well as for medical and industrial applications. Owing to its sophisticated beam transport system equipped with an advanced beam diagnostics, the beam parameters can be flexibly adjusted to the diverse requirements of research and application projects, making it a multidisciplinary facility.

The SNMS/SIMS-XPS assembly contains a secondary neutral mass spectrometer, a secondary ion mass spectrometer and an X-ray photoelectron spectrometer (XPS) with a common vacuum system. This arrangement enables the analysis of samples in ultra-high vacuum to be carried out without opening the vacuum chamber during the sample transfer. While mass spectrometry measurements can be performed in the SNMS/SIMS part of the system, the chemical state of elements can be determined in the XPS part. A complete quantitative surface analysis can be performed with high depth resolution (~1 nm) or high lateral distribution. n

The Spect photoelectron spectrometer is a recently commissioned equipment at Atomki, which is equiped to the SNMS/SIMS mass spectrometer in a common vacuum system. This arrangement enables the analysis of solid-state samples in ultra-high vacuum carrying without opening the vacuum chamber. While mass spectrometry measurements can be performed in the SNMS/SIMS part of the system, the chemical state of elements can be determined in the XPS part. A complete quantitative surface analysis can be performed with high depth resolution (~1 nm) or high lateral distribution.

The only Hungarian electron cyclotron resonance (ECR) ion source (ECRIS) operates in the ECR laboratory of Atomki. Being a part of the Atomki Accelerator Center, it is a stand-alone device to be used for basic research (atomic and plasma physics) and for applications.

MTA Atomki has installed the new Tandetron accelerator in May 2014 made by High Voltage Engineering Europa BV. In January 2015 a Duoplasmatron ionsource with the injector magnet, then a simple temporary switching magnet was installed. The Tandetron accelerator needs negative ion input and then produces high energy positive ion beam (in this case protons). In the meantime we also installed a 9-port switching magnet directly at the exit of the Tandetron, i.e. to a temporaty position. We can accelerate 200 keV - 4 Mev energy protons with 25 μA beam current.

Ha egy kémiai, biológiai, vagy fizikai folyamatban részt vevő elem izotópjainak aránya a folyamat során az egyes komponensekben vagy fázisokban megváltozik, izotópfrakcionálódásról beszélünk. Az izotóparányok változása fontos információkat szolgáltat a lejátszódó folyamatokról. A természetben előforduló izotópfrakcionálódási folyamatok során az izotóparány általában csak igen kis mértékben változik meg, ezért ezek nyomon követéséhez nagyérzékenységű berendezésekre van szükség. A Környezetanalitikai Laboratóriumban elsősorban a földtani és hidrológiai kutatások igényeinek kielégítése érdekében egy Thermo Finnigan gyártmányú Delta plus XP típusú stabilizotóp-arány mérő tömegspektrométert üzemeltetünk, amellyel a geokémiában legnagyobb jelentőségű öt elem (S, C, H, O, N) izotópjainak arányát a pontossági igényeknek megfelelően automatizáltan, számítógép vezérelten tudjuk mérni.

The MAP-215 type noble gas mass spectrometer is a Nier-type, high sensitivity, low volume system developed for the analysis of all noble gases (He, Ne. Ar, Kr and Xe). The mass spectrometer is equipped with a Faraday-cup and an electron multiplier for detecting low amounts of gas. Degassing of the samples can be carried out in different temeparture steps from 20 to 2000°C. Cleaning of the noble gases from the dirty gases (e.g. H2O, CO, CO2, hydrocarbons) is made by non- evaporable getters.
