Muon Detector Day 7

We started today by checking what the efficiency of the old scintillator fluid was after leaving it over night.  It ended up being almost 50% efficient which was higher than we expected but obviously still not very good.  Next, we changed the fluid from the mason jar to the new fluid.  To do this we had to go to a chem lab to dispose of the fluid correctly and work under a fume hood.  It was quite the process trying to get a small amount of fluid out of the 5 gallon tank without spilling everywhere but we were successful in doing so.  We then set up the apparatus again, this time with the new fluid and left it running for 2.5 hours.  This time it was 97.6% efficiency which is a huge improvement from what we had previously.  We finished the day off with brainstorming ideas for a structure we could build to hold an entire tank of scintillator fluid with the paddles fixed above and below it and a PMT mounted on top of it.
