Phys4051: Methods of Experimental Physics I 5 credits This course is the first of a two-semester sequence on the techniques used in a modern experimental physics laboratory. Because of the importance of electronic instrumentation in today's physics experiments, the first semester of the laboratory will deal with the use of analog and digital techniques for processing electronic signals and with the use of computer instrumentation. The second semester laboratory will consist primarily of a single experimental project taken by the student through the stages of design, proposal, construction, data acquisition, analysis, oral presentation, and written report. Class and Laboratory Schedule: All lectures are held in Tate Hall 110. Mandatory Labs and Optional Recitation Sessions take place intate Hall B30.

Information, announcements, and materials will be posted on the class Moodle. The Moodle for the course should appear in your courses at http://www.myu.umn.edu or can be accessed directly by logging into https://moodle.umn.edu Important information and announcements made in class may not be posted on the web site. Lectures: Three lectures will be given per week: M, W, F, 2:30-3:20, in Tate Hall 110. You will be responsible for all announcements made in class. Recitation (optional): An optional recitation section will be held in the MXP Lab (Tate Hall B30) Fridays, at 3:35 PM. Course-related topics will be discussed in an informal manner. This session is optional and will be held as long as there is sufficient demand. Textbooks, Scripts and Lab Manual: The required textbooks are P. Horowitz and W. Hill, The Art of Electronics, 3 rd edition J. Essick, Hands-On Introduction to LabView for Scientists and Engineers, 3 rd edition Script (available on the class Moodle site) J. Mans, Electronics for Experimenters The course lab manual will be provided during the first lab session. Reading: Regular reading assignments are specified in the lab manual. You will be responsible for reading, either in the course text or in other references, material sufficient to gain a full understanding of what you are doing in the laboratory. Labs: Laboratory sections meet twice a week for two hours each in Tate Hall, room B30.(phone: 626-3329). Students will work in pairs, must attend their assigned laboratory periods, and must actively participate in the lab. Labs begin Tuesday, September 6. To keep up, some students may find that a number of hours must be spent in the laboratory each week in addition to their scheduled hours. Access to the laboratory may be obtained during weekdays from 8:30 AM to 5:30 PM. Laboratory Reports: Three different types of lab reports exist, depending on the chapter in the lab manual covered. Chapters 1, 2, 4, 5, 7, 8 and 9 are to be handed in as short reports and count a maximum of 15 points each. In these reports all questions in the lab manual must be answered. In approximately 3 pages, you should describe your work in a way that is comprehensible to the TA, using complete English sentences where appropriate, demonstrating an understanding of the material. The reports of chapters 11, 12 and 13 will be submitted in the form of a video lab report. These presentations should be about 10 minutes long and will count for a maximum of 23 points. More detailed information about the expectations for these reports and instructions on how to prepare them will be provided in class and on the course Moodle page. The reports of chapters 3, 6, 10 and 14 are to be longer, typed and in a more complete format. They each count a maximum of 30 points. They should contain a complete description of the exercises and results, including analysis, diagrams and plots, as well as answering all questions in the lab manual. In addition, you should record all your laboratory results in a lab notebook. 2
Lab reports cannot be re-written. All the figures in the lab manual are posted on Moodle and on the mxp physics website, you can use them instead of reproducing them. More detailed information and a sample short, video, andlong lab report can be found on the moodle site. Long reports must be typed, use a 12 point font, must be double spaced and may not exceed a maximum of 10 pages. All reports will be submitted electronically through Moodle. Short reports can be a scanned image of a handwritten report. Reports need to be submitted as pdf documents. It is the student s responsibility to verify that the uploaded file is not corrupted or incomplete. Please check the integrity of the uploaded file by opening it with Adobe Reader. Scanners are available in Tate Hall B30. For the exact due dates, location and rules consult the class Moodle. Late submissions will not be accepted, unless there is a valid, documented medical or university approved reason. To pass the class you must have submitted all of the reports but for two of the short ones. Grade Policy: Grading for this course will be based on an absolute scale of 444 points, distributed according to the following table: Exam/Assignment Number of Exams /Assignments Possible Points Each Total Possible Points % Total Grade Final Exam 1 50 50 11.26% Exam 1 1 25 25 5.63% Exam 2 1 25 25 5.63% Long Reports 4 30 120 27.03% Short Reports 7 15 105 23.65% Video Reports 3 23 69 15.54% Homework 10 5 50 11.26% Total Points 444 100.00% Note that your lab work makes up approximately two thirds of the total grade! Generally speaking, A's will be awarded for outstanding work that shows mastery of the material as demonstrated in both the lab reports and examinations. B's will be awarded for good work that exceeds the basic course requirements. C's will be awarded for work that meets the course requirements. Work that falls short of the basic course requirements will earn a D. F's will be given in cases of seriously deficient work. It will be very difficult to get an A or B in this course without doing well on the exams. For this reason, make every effort to really understand what is going on in lab! Exams: 3
Two 50 minute exams will be held. The first will cover analog electronics and the second will cover digital electronics. The final exam will be 10:30 a.m.to 12:30 p.m. on Monday, December 18. The final may contain a practical lab component, which would take place during the last week of classes. Homework: 10 homework assignments will be posted on Moodle. They will be submitted at their corresponding due dates through Moodle. Spring Projects (Physics 4052W): In order to prepare for the second semester of the course, we will ask you to begin thinking about potential projects for the spring semester. The lecture on October 23 will provide information to help you prepare for this. We ask that after that lecture you prepare a letter of intent which describes the project that you would like to perform. This letter will be due on November 6. The letter of intent will not be graded and will not be required from students who will not take PHYS 4052W. It is however necessary to begin planning this semester to make sure that your proposed project is feasible and to resolve conflicts if multiple students decided to perform identical projects. Academic Honesty: All work on exams and the final examination must be your own, and you must follow any rules stated for a given examination. No collaboration is permitted on any of the exams in this course. Your lab journal and your written lab reports should also be your own work, although you are expected to collaborate on collecting and discussing the data. Any other work submitted for a grade must be completed according to the guidelines established by the instructor or TA's. Note that it is understood that in handing in your lab report you have actually completed all of the bench work and that the data presented in the reports are your own. Failure to adhere to these standards will result in penalties ranging from zero on a particular exam or assignment to expulsion from the University.
