Tested the life unit for World View. We were out of LN so I had to run to Madco to get a small 35L Liquid Nitrogen tank. The results of the test were a little different than the previous test done in August. At higher frequencies, the loss factor dropped lower. Scott P. talked to Connor and Paul about this and they suggested realigning and making sure the setup was exactly the same as last time. They also suggested testing an undamped specimen and comparing to before.
I checked the pictures of the setup from last time and discovered that there was a washer that I was using that wasn't there before. I redid the setup and retested the isolator. The results came out exactly the same.

I also tested about 5 more WISE isolators. I am now lubing the bolts with Braycote and changing them every other isolator.
