New Mexico Tech's Physics 451L
               Senior Lab

             At New Mexico Tech, physics seniors are required to take PHYS 451L, senior lab, for graduation. This course familiarizes students with laboratory equipment including the grating spectroscope, the Fabry-Perot interferometer and the scanning tunneling microscope. The experiments are designed to bring together concepts learned during previous physics courses -- stengthening physical intuition and understanding. In addition to getting hands-on experience, this course introduces students to error analysis of data.
             The course is structured differently from most lab courses at Tech. Most lab classes complete one lab each week during the scheduled class period. In senior lab, the class period is used as a lecture period to get the students familiar with the lab equipment, to go over the theory behind each experiment, and to teach students how to do error analysis of their results. Students then do the experiments outside of class. This has the advantage of allowing experiments to be a bit more complete -- rather than cutting the experiment into pieces which would fit into a two hour time frame.
        Students get a choice of four of the following labs to complete over the semester:
        •  H-alpha Isotope Shift
        •  Sodium D Line Splitting
        •  Zeeman Effect
        •  Scanning Tunneling Microscope
        •  Infrared Thermography
        •  Hall Effect
        •  Franck-Hertz Experiment
        •  Alpha Particles
        •  Nuclear Magnetic Resonance

             For each lab chosen, the student must write up a clear, concise abstract.  At the end of the semester, the student must also write one complete lab write-up  from any of the labs he or she has chosen to do.
