Students will be required to maintain a laboratory notebook (consistent with any proprietary requirements) and will present a colloquium talk on their internship work. A letter of evaluation from the student’s supervisor will also be required. Typically, full unit internships require approximately 140 hours for the semester. Specific requirements will be presented by way of a contract signed by the students. If this internship is used to fulfill a major requirement in the applied physics track, it must be letter-graded and for a full unit of credit. Prerequisites: permission of department head and instructor and PHYS 312. Enrollment in an internship course requires students to attend an orientation prior to beginning work at their internship site.
