…questionable materials. 4. Does the machine have adequate ventilation? Yes. A dual exhaust machine provides efficient removal of cutting fumes. The vacuum cutting bed provides material hold-down and removes smoke from through-cutting. An additional top exhaust port removes residual smoke from engraving…

…. Single photon ionization (SPI) with vacuum ultraviolet (VUV) light is a particularly soft ionization technique, well-suited for detection of both aromatic and aliphatic species. Problematic, however, is the generation of the VUV light. In general, the vacuum ultraviolet (VUV) light sources for SPI…

…required energies (as high as 250 MeV) can cost more than $50 million. Furthermore, proton beams are difficult to handle, requiring large magnets and a vacuum delivery path. As a result, the gantry that directs the proton beam into the patient is massive. For example, at Loma Linda University Medical Center…

…systems of interest are often comprised of multiple components with different vapor pressures. Another advantage is that PLD can be performed in high vacuum, or in low pressure of reactive gases. A single film can be made in a relatively short period of time with a quick turnaround. By monitoring the number…

…they do not absorb in their spectral window of use. Hence, they usually withstand powerful laser radiation in that spectral range. However, in the vacuum ultraviolet (VUV) almost all materials absorb strongly, especially 157nm light. Thus, 157nm radiation from F2 lasers may extend the well-known advantages…
