The Sub-atmospheric Technology Group posted a guideline defining TT Active Vacuum Candidates. It includes indications, contra-indications and special considerations. Please have a look, we look forward to your comments and hope this generates some dialog on the webpage. If you are not an Academy member you can receive a 2 week trial period to have a look.
