Ever dreamed about building an x-ray tube? Or coating your own telescope mirror? Maybe even constructing an electron microscope? Perhaps you are a high school science teacher who would like to introduce simple yet interesting electron, ion and plasma physics experiments and demonstrations into your classroom. People the world over are involved in projects like these and the common thread is the use of vacuum technology. the Bell Jar is the resource that you need to join this network of hobbyists, students and educators.Please check out the VPAL (Vacuum Principles and Applications Laboratory), a new educational product from The Science Source/Daedalon.Updates as of 4/02/09News about this SiteThe Second Five Years compilation is actually moving along. I've set aside several days to just plug away at it and it should be done by sometime next week. This has been a trial as most of the articles were written on a different OS and application. I think it's almost worse than rewriting the articles from scratch because the problems are varied and niggling. I have added a very low cost single stage mechanical pump to the Chambers & Supplies page. I have purchased and tested two of these and the performance is excellent and the price is incredible. For Technology and Physics Educators: I have expanded the coverage of vacuum training systems to include, in addition to the forum topics, information on accessories and support services. A new button has been added to the menu on the home page. The updates page has been revised. I have added a collection of notes and letters from Frank Lee concerning his thoughts on small homemade diffusion pumps. This may be found on the Articles page in the Frank Lee section. A new article A Primer on Using Ace Threds has been added to the Articles & Publications page. See the listings under Volume 11. An Updates page has been created as an aid to finding out about what's new on the site. |

| Freedom is never more than one generation away from extinction. We didn't pass it to our children in the bloodstream. It must be fought for, protected, and handed on for them to do the same, or one day we will spend our sunset years telling our children and our children's children what it was once like in the United States where men were free.
