GV10x UHV Downstream Asher

Competitive sources discovered by internet search may be HV but not UHV compatible. Vacuum components necessary to convert HV plasma sources UHV compatible require an expensive isolation valve and pre-pump components.

The GV10x UHV DS Asher is designed to reside on a UHV chamber after chamber plasma cleaning in millitorr range without breaking vacuum. This one of a kind in-situ plasma source eliminates the need for a costly isolation valve and pre-pump.

The GV10x Downstream Asher’s ability to remove contamination from Electron Microscopy samples and chambers is well recognized by electron microscopists worldwide. Contamination control improvements beyond traditional methods: 1st generation plasma cleaners, LN2 trapping, UV exposure offer EM researches freedom to remove carbon artifacts in minutes and mitigate chamber contamination buildup.

Ich wollte Ihnen sagen, dass der GV10x, den Sie sandten, richtig installiert wurde, nahm es mich wie gar keine Anstrengung, es arbeiten zu lassen. Ich prüfte es mit einigen Proben, und die Wirkung war wirklich erkennbar.

An extended study on an advanced method for the cleaning of carbon contaminations from large optical surfaces using a remote inductively coupled low-pressure RF plasma source (GV10x DownStream Asher) is reported. Technical and scientific features of this scaled up cleaning process are analysed, such as the cleaning efficiency for different carbon allotropes (amorphous and diamond-like….  more…

Characterization, optimization and surface physics aspects of in situ plasma mirror cleaning Although the graphitic carbon contamination of synchrotron beamline optics has been an obvious problem for several decades, the basic mechanisms underlying the contamination process as well as the cleaning/remediation strategies are not understood and the corresponding cleaning procedures are still….  more…

Downstream Plasma Technology for Cleaning TEM Samples on Carbon Films Plasma cleaning has become an essential step in modern analytical electron microscopy, which requires contamination-free samples for imaging and elemental analysis. However, the dilemma for carbon film TEM grid users is how to plasma-clean the hydrocarbon contamination while preserving the carbon support film. In order….  more…

The GV10x Downstream Asher’s ability to remove carbon contamination is a major advancement above traditional methods of mitigating contamination using cold trapping, nitrogen purging, and other plasma cleaners. The GV10x, with its extended power and pressure range (5 to 100 Watts and 2 to <0.005 Torr), represents a paradigm shift in the carbon HC control in SEMs and other analytical instruments including Mas Spec, XPS etc.

As nanoscience progresses, electron probe analysis becomes more challenging: electron beam energies decrease, precursor gas use increases and maintaining high resolution becomes more dependent on maintaining low carbon and HC contamination levels. Downstream plasma process accomplishes eliminating hydrocarbon contamination accumulation and specimen cleaning simultaneously quickly, and easily. Unlike kinetic cleaning in usual ‘plasma cleaners’, the downstream plasma process is a gentle chemical (virtually zero K.E.) process. This process has revolutionized the means to eliminate carbon and hydrocarbons in vacuum chambers.

The Gentle Asher has been specifically designed to expand the GV10x investment for sample cleaning prior to inserting into the EM chamber. The Gentle Asher Chamber, which is integrated with a GV10x connected GA/GV, is ideal for preventing black scan square deposits.

By simply shifting the GVx Source onto the Gentle Asher Chamber, this technique easily and effectively removes impurities from samples and TEM holders without causing any considerable damage and at the same time controls hydrocarbon levels in SEM, TEM, CDSEM and FIB. When samples and holders are pre-cleaned, it prevents contamination of the chamber gas phase and reduces the time involved in microscope cleanings.

MCA

A mobile plasma center that cleans, stores and processes SEM/TEM samples/holders and other sundry items in a small chamber. The Qwk-Switch™ Source facilitates shifting hydrocarbon mitigation to other SEM or FIB sites for in-situ chamber cleaning.

The MCA chamber accommodates an assortment of specimens to remove hydrocarbons, hydrophilizing surfaces, storing and cleaning three TEM holders and specimens with ibss signature GV10x Downstream plasma fitted onto a portable S/S cart.

The Chiaro similar to MCA but distinguished by turbomolecular pressure & speed. An optional optical microscope can be installed to mount and observe specimens during plasma conditioning and potential leak observation from liquid/gas specimen cells. Plasma processing at lower vacuum increases plasma processing activity. To meet requirements of viewing gas and liquid sample cells in TEM holders the Chiaro performs the functions of leak checking, gas/liquid E-Chip viewing while mounting, surface hydrophilization and plasma processing.

  • Easy TEM specimen loading through swing away chamber port
  • Swing away stereo mic with keyed re-registration
  • 5X mag w/6” working distance, LED illumination to view loading
  • Pressure monitor possible gas/liquid cell leaks at <2e-5 Torr
  • and much more..
