Born in 1988 on December 17th, in Las Vegas, Nevada, to the parents of Douglas and Annette LeBaron, I am currently 18 years old and have graduated from Orofino High School in Orofino, Idaho as a Co-valeodictorian. I am a very active person being the member of various clubs and groups throughout high school. I have taken 6 AP classes and several college health credits as well. I am ready to begin college this fall semester at ISU and I believe this intership will start to condition me to college life. I owe this opportunity to participate in this internship to my science teacher Mrs. Riley. She is the one that learned about it and then passed the information on to me as well as encouraging me to apply. She is also the one who taught me nearly everything I know about Physics and Chemistry. I would like to thank Mrs. Riley and all my teachers for the knowledge they have given me as well as my family and friends that have supported me through any endeavors I have taken on.

The adventures of Steve Lowery and Nathan LeBaron
Cosmic Ray experiments
Orientation of Compass to Obtain Direction
!
As of 7/20 we've discovered a myriad of problems with our cosmic ray telescope and system, including:
~One of our scintillators wasn't fully covered - so a good deal of our readings we're the result of the fluorescent lights overhead. This may partly explain why our singles counts we're greater in proportion to coincidence counts during the day (the lights are turned off at night in the Laboratory for Detector Science).
~Neither of the high voltage connections read accurately or consistently.
~Both PMT to NIM Bin connectors have shorted out. The first "victim" was Dr. Forest, who, mildly amused by the surprise, immediately poked the connector threateningly at Dr. Kole, who responded, "Get that the hell away from me!". Later Dr. Kole was shocked while working on the set-up anyway.

Solar FLux
(Introduction Here)
x = Distance Most Light Travels Through the Atmosphere to Reach the Solar Cell
d = Shortest Distance from Solar Cell to Space
= Angle Between the Ground and the Line of Variable x
I. = Intensity of Light Above the Atmosphere
I = Intensity of Light that the Solar Cell receives
µ = The absorption of the atmosphere - varies depending on certain conditions, including barometric pressure
___________________________________________________________
I = I. e^(-d/sin())
I/I. = e^(-µd/sin())
ln(I)/ln(I.) = -µd/sin()
ln(I) – ln(I.) = -µd/sin()
ln(I) = -µd/sin() + ln(I.)

Nathan LeBaron
Born in 1988 on December 17th, in Las Vegas, Nevada, to the parents of Douglas and Annette LeBaron, I am currently 18 years old and have graduated from Orofino High School in Orofino, Idaho as a Co-valeodictorian. I am a very active person being the member of various clubs and groups throughout high school. I have taken 6 AP classes and several college health credits as well. I am ready to begin college this fall semester at ISU and I believe this intership will start to condition me to college life. I owe this opportunity to participate in this internship to my science teacher Mrs. Riley. She is the one that learned about it and then passed the information on to me as well as encouraging me to apply. She is also the one who taught me nearly everything I know about Physics and Chemistry. I would like to thank Mrs. Riley and all my teachers for the knowledge they have given me as well as my family and friends that have supported me through any endeavors I have taken on. Thank You.
