Arterium

By KMLabs

Vacuum beamline (e.g. KMLabs Arterium). This so-called vacuum beamline is an interconnected, evacuated, tubular conduit, which incorporates modular components that may be optionally and readily installed (by the customer) into the beamline and HHG system, as needed—without compromising the beamline vacuum. These modules are used to reject excess IR light, filter the EUV spectrum, focus the EUV light, monitor the EUV power, replace capillary waveguides, and more. Our Arterium vacuum beamline takes into consideration the following design aspects: - The fundamental 800 nm light driving the HHG process is removed so that only the EUV or soft X-ray laser light can eventually interact with the sample, without any of the residual infrared light. - High pointing stability is guaranteed by the fiber generation system. - Depending on the experimental requirements, a monochromator is incorporated to select EUV photons from a single harmonic peak. - To propagate without significant attenuation, the beam is maintained under vacuum. - Space considerations are considered, as the total system needs to be appropriately sized for a laboratory setting. - Focusing of the EUV beam is considered if the experiment requires a particular beam spot size. - For a system with multiple experimental stations, a beam selector module is available to direct the EUV photons to the experimental / diagnostics chamber of choice. This can be optionally equipped with focusing toroids, gratings, or mirrors, depending on the experiment need. - Optics and windows are carefully selected to maximize efficiency and minimize dispersion effects which would distort/prolong the ultrashort pulses. - Diagnostics are incorporated so the beam quality and stability can be easily monitored.
