Inspcetion of viewports - HAM7 & HAM8
The first round of the viewport inspection was done on 02/21/2023. The HAM7 and HAM8 chambers were inspected - at the same time, all the ports were labelled.
The motivation behind these activities is that a faulty viewport design was found lately, therefore at least all the recently added viewports should be inspected. Moreover, to minimize the risk of catastrophic failure, all the viewports will be inspected in the near future.
In this round, there were no major issues found, see the detailed summary below. By the end of this inspection run, this will be uploaded to the DCC as well, with pictures and more detail.
