The past two weeks have been "ughhh...", at best. JJ went to India (that's where he's from) for a couple of weeks, so I've been on my own since he left. He left me three things to do: calculate the pressure drop from the argon flowmeter to the ion source chamber, read up on how to operate the turbopump, and leak test the helium recirculation cart. I've got a new value for the pressure drop, but I'm not that confident in the result. I was able to read up on the turbopump, but there's only so much I can do without turning it on. Finally, I was able to leak test a little bit of the cart, but not all of it. I found a really big leak! However, I can't fix it. Because of that, I can't get the background noise of the detector low enough to reliably check the rest of the cart.
What sucks is that I hit all of these roadblocks at the end of his first week away. Last week was really dull since I really couldn't do much. Thankfully, there were a couple of meetings with the nuclear physics group and a student symposium I had to present for, so that took up a bit of my time. I'm glad JJ is getting back so that we can get back to work!
I feel kind of bad that I wasn't able to completely finish everything... however, I've done what I can and I'll just hope that he's pleased. -shrug-
