Production
- Casey and Tina will come this Saturday to string wire frame #30. Dave will then work on it. This is the last frame we need for package #4, but will make two more spare wire frames. Answering Eugene's question: we will have to make four more cathodes to finish with the package production, but eight more cathodes will be done as spares.
- The gas (40/60) will be delivered to Blue Crab next Wednesday. In the mean time we found a 40/60 gas bottle delivered by mistake to JLab. We already started using it for the package #3 tests, since we didn't have Ar. Nevertheless, we decided to take it from JLab and use it at Blue Crab to start testing package #1. We expect to have Ar bottle soon, to be used at JLab.
Cathode corrosion test
- No news, the lower limit now for the time before corrosion is 1-3 years, depending on the activation energy. We will continue with the tests till Monday, then will open the chamber and prepare another set of samples to be tested at lower (65degC) temperature. This will give us an estimate of the activation energy within a month.
Engineering
- Bill has ordered some part of the cooling system and is working on the documentation for the rest.
- Bill is in contact with Ron Bartek and Paul Powers about possible solutions for the cooling of 126. After the meeting Walt Akers came with a solution to install three ceiling fans to blow the hot air to the high bay (target) area using flexible ducts. Cooler air from the high bay will be drawn through a louver that will be mounted at ground level.
Electronics
- Chris: Daughter cards shipped for population last week, company confirmed that all is ok, will have them ready next week.
