Three DARPA-funded research teams have completed a foundational study of chip-scale vacuum pumps by inventing three very different approaches to removing air from a sample chamber with a volume of one ...

Figure 1. Vacuum chamber (left) and hot bond controller (right) along with a vacuum source for the inner bag and chamber are all connected and ready to run a double vacuum debulk (DVD) process. Inset ...

IN an effort to explain the breakdown of proportionality between ionization current and gas pressure in cavity ionization chambers, Greening 1 postulated the transfer of slow electrons between the ...

Engineers still seem to prefer stainless steel vacuum chambers over aluminum ones. But aluminum provides benefits for vacuum chambers, especially for ultra-high (UHV) and extreme vacuum applications. ...
