Revision as of 16:16, 7 April 2020
Put here all relevant material for students
To do
- Email to students with Zoom details
- Be more specific about the way of grading (Niels)
Guidelines
Lecture format:
- Divide each lecture in 2 (or 4) topics,
- Ask the students to write lecture notes of 4-6 pages of a topic in groups of 3 students,
- Derivation of equations in an appendix
- A template of the lecture notes for each topic will be provided.
Exam:
- Your written lecture notes
- Each group takes lecture notes on 1 (or 2) topic(s) they were not involved in, and will present this in 15 minutes to the rest of the group.
- Each group will get a total number of points which can be subdivided over the different students.
Groups
Groups of 3 students each to work on the assignments.
- Group 1: Tjip, Leon, Alessia
- Group 2: Marjolein, Barbara, Nigel, Niels
- Group 3: Anastasis, João, Maricke
Lectures
Lecture 1: Intro and Power Spectral Density
The Intro should contain (group 1):
- What do we measure with an interferometer?
- First watch Kip Thorne's lecture: https://surfdrive.surf.nl/files/index.php/s/hmCWcFxSrilUeZy
- Write notes according to slides 6 - 12: slides
- The effect of Gravitational Waves on test masses (mirrors)
- See this Saulson lecture, this topic is covered from about minute 45 onwards: https://www.youtube.com/watch?v=m4IKvv0AqAI&list=PL04QVxpjcnjgs5aJ-BN3CRiMhJNyB1Ekr&index=4
- You can also use Saulson Chapter 2: https://surfdrive.surf.nl/files/index.php/s/xATgIBO2OOEIM5o
- Write notes according to slide 18: slides
The PSD chapter should contain (group 2 & 3)
- Sensitivity curves - Power Spectral Densities
- Lecture Kip Thorne: https://surfdrive.surf.nl/files/index.php/s/5qrbQhf3foFNh5C
- Saulson Ch4: https://surfdrive.surf.nl/files/index.php/s/rGu64pFLNai2Ze1
- Blandford and Thorne section 6.4 (at the end of this page)
- Write notes according to slides 22 - 27: slides
Date to hand in assignment: Wednesday April 6
Lecture 2: Gaussian beam, Fabry-Perot cavities
The chapter ‘Gaussian beam’ should contain:

The chapter ‘Optical cavities: fields amplitudes’ should contain:
- definition of optical cavity (slide 17)
- mathematical computations of the involved fields (slides 18-20, 22)
