= Week of September 14-18 =

16th of September
I was unable to go into the lab today due to my own schedule and I couldn't schedule to do these hours with Thursday because I am also busy Thursday. I set up with Becky to come in another hour for the next two Fridays so this will account for the two hours that I missed today.

18th of September
I went into the lab today for about 3 hours and 15 minutes. While the scope was really drifty, I am hoping this is going to stop soon, I saved 12 scans and while the laser was not producing a large amount of expansion for the gold it was actually hitting the sample. I tighthened all of the screws for the laser box to see if this would amount to any increase in voltage being sent to the laser and it did, but it was not a large amount. I also tested all of the batteries in the lab to see which cobination of two batteries emmitted the most volts and used these two batteries. This also did not yield a significant change. Next time I am in the lab I am going to take a field trip to the physics stock room to buy some batteries. The amounts that the laser was expanding the gold were similar to those we had been experiencing before we changed the batteries in the summer. Dr, K wasn't in the lab or in his office again today.
