Feedback from preliminary detailed design
MSD team: P16371: Controlled oscillating meniscus test fixture
Presentation date: December 10, 2015
Harold: Next week’s meeting is not a presentation. The purpose is to go over what was done, what was
planned to be done, what hasn’t been, and what you are going to do about the unfinished items. I
expect it to be an hour or less. I want to see drawings and documents. I also want to see risks and what
hasn’t been done with regards to the design.
Harold: EDGE site should be complete by the gate review. Make sure that is up to date. We may utilize
during our gate review meeting.
Pruthvik: Oxidation on the copper surface is fine. We are only concerned about the roughness of the
surface.
Pruthvik: You can get another camera from the lab.
Pruthvik: Try running your oscillations test for a longer time period to see if you reach a steady state
where the water level is not changing. Also, use a smaller tube. You should be able to find something in
the chemistry department. A smaller tube will allow you to quantify the oscillation amplitude more
easily.
Harold: Make sure the inside of your test tube is squeaky clean.
Harold: Take notes of what you are doing. It is really important.
Pruthvik: You will need enough amplitude so that the meniscus become unpinned from the copper chip,
expands, then becomes unpinned from the copper chip again, and shrinks back to its original size.
Pruthvik: Before you leave for break, conduct some testing with the polished copper chip. Otherwise,
you will need to polish the chip again after you get back from break and start MSD II. Create a stable
meniscus on the copper chip with a heated plate. I want to know if you can maintain a stable heated
meniscus.
Harold: You can probably put a solvent or oil of some sort on the copper chip in order to prevent it from
oxidizing.
