Dear colleagues,
As a long time (former academic) member of this news group it is my pleasure to bring to your attention the website
www.amsterdampiezovalve.com
This website provides information on a piezo valve that produces short (<20 microsec) and intense pulsed atomic and molecular beams. It can operate both in continuous and in pulsed mode (DC - 5 kHz). The short pulse duration makes the valve very suited for applications in combination with pulsed lasers. Because of the short pulse duration the valve consumes typically a factor of ten less sample relative to a conventional pulsed plunger valve, saving a lot of sample that is otherwise wasted. The low gas load makes the design of the vacuum apparatus much simpler, requiring smaller pumps and saving financial resources.
The website also contains a selection of references/links and pdf-publications of the vast original scientific literature on the production and characterization of (seeded) atomic and molecular beams. If you feel an important reference is missing do not hesitate to contact me.
