Examination protocols
All examinations were passed in Cologne, so the protocols are primarily useful for students of Cologne university. They are supposed to help them prepare for an examination. Since they also contain remarks about the examinations' atmosphere, they can also aid in chosing an examiner.
- Experimental physics diploma
Examiner: Prof. Eckart - Theoretical physics diploma
Examiner: Prof. Zirnbauer - Mathematics diploma
Examiner: Prof. Kawohl
About ordinary differential equations and elementary differential geometry - Experimental physics pre-diploma
Examiner: Prof. Micklitz - Theoretical physics pre-diploma
Examiner: Prof. Zirnbauer - Linear algebra pre-diploma
Examiner: Prof. Thorbergsson
Lab reports
This section contains some reports of the experiments we conducted as part of the Fortgeschrittenenpraktikum at Cologne University in 2002. Our group consisted of Tanja Kotthaus, Fatma Kul, Christian Stromenger, and myself.
These reports are a resource for preparing oneself for the experiments and the preceding oral examination. They are presented here for this purpose.
While these reports have all passed the examiner's scrutiny in the present form, they are not necessarily all fully correct. Bear this in mind when preparing for the labs.
- Optically pumping rubidium
- Mößbauer effect (This is a postscript file)
- Microwave radiometer
- X-ray spectroscopy
Attention! This experiment differs significantly from the official lab manual. You had best ask the person responsible what precise experiment you will have to conduct. - Nuclear spin resonance
- Hydrogen isotopes.
Linux
Some things are hard even when using linux. Here I have noted what I had to do to build a diskless workstation and to get a DEC2000-t DVB-t-receiver (Hauppauge) running in Cologne.
Here you can find out how to set up a HP (TM) OfficeJet (TM) 6500 All-in-One Wireless.
