Course description and aims

In this course students will work on three basic physics experiments. They will be performed once per two to three weeks, and students will be given a preparation period for each experiment in order to gain an understanding of the experiment details. Teams of two will be created for each experiment, which will be performed in cooperation. After each experiment, each student will create a report to submit.
In experiment A, students will use a spectrometer that functions due to diffractive grating, and a digital camera to measure lights from hydrogen and helium atoms, and the light from surrounding light sources. In experiment B, students will use a NaI scintillator to measure gamma rays. Students will also attempt the simultaneous measurement of 2 gamma rays in a measurement that uses cobalt ray sources. (Exp. C is not carried out in this term: In experiment C students will capture cosmic ray muons which are charged particles, measuring their life. Students will learn calculation methods for the kinematics of three-body decay and the basic coupling constants of weak interaction.) In experiment D, students will carry out the measurement of the temperature dependence of Refractive index of the crystal using Michelson interferometer.
The lecture is partially given in English.

Student learning outcomes

We will run three basic and important physics experiments, and consider the physical laws at play, getting a grasp on physics principles. In experiment A students will observe a light from the Balmer series hydrogen and helium, and compare them with calculations from quantum mechanics.
In experiment B students will use basic gamma ray measurements to understand the interaction between gamma rays and matter.
(In experiment C students will measure the life of cosmic ray muons, finding the fundamental constant of weak interaction. )
In experiment C students will learn the basic of the laser interference and gain the knowledge of the feed-back system.
Students will refine through practice their handling of experimental equipment and data processing technology they learned to use as an undergraduate, and learn central technology that will have applications for master's thesis research.
