There are right presently 7 functional windows for the Dragon Ionization Chamber.
All of them have been tested and there is a record of the pressure both on the ionization chamber and the other side of the window for each. A detailed spreadsheet of the pressure tests for each window can be found in the attachment of the following DRAGON hardware elog: https://elog.triumf.ca/Dragon/Hardware/490

The highest pressure is just an indicator, some of them could certainly hold higher values
