Fortgeschri+enes Experimen2eren
Advanced Physics Lab
Goal of the lab class
• hands-‐on experience with complex experiments
• data analysis
• data interpreta2on
• scien2fic report wri2ng
Every student is supposed to complete 4 experiments within one semester
What kind of experiments do we offer? I. Regular experiments: Ø General Physics (see Physics I-‐III) Ø Nuclear-‐ and Par2cle Physics Ø Op2cs (Quantum Electronics) Ø Solid State Physics Ø Astrophysics
II. Advanced Student Labs (ASLs): Ø Experiments close to research in a research group Ø Sign-‐up and work as a team of 1–4 students Ø Some ASLs count as two regular experiments
Advanced Student Labs (ASLs) Solid-‐State Physics • Prepare a semiconductor structure in a
clean-‐room using photolithography techiques
• Op2on: measure the quantum Hall effect on your structure
ParBcle Physics • develop a novel tracking detector using
scin2lla2ng fibres • study cosmic rays, detect muons, ...
Advanced Student Labs (ASLs) Astronomy • Observe and take pictures of planets,
galaxies, ... • Measure proper2es of back-‐sca+ered
light
Quantum OpBcs
• Quantum dots as single photon sources
• Hanbury-‐Brown-‐Twiss experiment
• Atom-‐Photon interac2on
• Entangled Photons • Mach-‐Zehnder Interferometer

Regular experiments in HPP
Opening hours (only during semester): Mon – Fri, 8am – 6pm, except Thu Ø Labs are closed during semester breaks Obligatory lab class day: Mondays Ø Assistants are available on Mondays
(personal appointments possible on other days)
Procedures Step I: Sign up for an exeriment Ø Mon 9.30 – 10.30, HPP H12 Ø Wed 9.30 – 10.30, HPP H12 (new) Step II: Perform experiment Ø typically within 3 weeks Step III: Return experiment (HPP H12) Ø (electronic) signature "measurement
finished" from assistant required
Step IV: Write report Ø hand in report to assistant Ø make correc2ons required by assistant Ø (electronic) signature "report handed
in" from assistant
Step V: Hand in report to Profs
Working as a team
You can work on selected experiments as a team, but:
Ø Each student performs an independent data analysis
Ø Each student writes his/her own independent report
Star2ng an experiment
Ø Carefully read the instruc2on manual before you
meet the assistant
Ø Familiarize yourself with safety ma)ers of the
experiment
Ø Consult addi2onal literature, if you do not understand everything in the instruc2on manual
Ø Meet the teaching assistant before you start to work
on the experiment
Lab-‐book
Ø Each experiment starts with a lab-‐book entry of its
2tle
Ø Use the lab-‐book to write down notes about the experiment, experimental procedures, es2mates, ...
Ø collect the assistant's signatures "measurement
finished" and "report handed in" in the lab-‐book
Rules:
Ø Measurements should be finished within 3 weeks
Ø Reports should be handed in not later than 3 weeks ager finishing the experiment
Ø ALL reports have to be handed in (to the assistant) before
the end of the semester.
Ø Incomplete Experiments expire at the end of the semester
If problems arise
Ø Try to solve experimental problems first on your own
Ø If something is broken and you cannot repair it yourself:
contact the assistant
Ø In excep2onal cases, the lab technicians will help
Ø Any accidents (even the smallest) have to be reported to
the Professors
Scien2fic conduct –plagiarism ETH Zurich–Guidelines for Research Integrity At the ETH Zurich research is founded on intellectual honesty. Researchers at the ETH Zurich are commi+ed to scien2fic integrity and truthfulness in research and peer review. ETH Zurich–ZiBer Knigge Ein Plagiat ist [...] ein Disziplinarverstoss und mündet in einem Disziplinarverfahren.
