Who am I(and what do I do at
MIT?)• Prof. Gunther Roland• Office: 24-504• Phone: x3-9735• AIM: PhobosRolandG• E-mail: [email protected]• When I’m not teaching:

What do we do at LHC ?• Make the Hottest Matter in the Universe– 100.000.000 times hotter than the surface of the sun

Getting started
• Find a good partner– 18 units: 6 in lab, 12 outside lab
•this is not an overestimate– make sure you + your partner can coordinate schedule and work together efficiently
– need to form partnership by next Monday•1st experiment starts next Wednesday
Sep 3 2008
Section organization• Max 16 students/section• Some sections are more crowded than others– amount of help you can get is ~ 1/enrollment
– Contact lead instructor (i.e. me) if you want to switch
– Sections need to be fixed before 1st experiment

Introduction
• See first pages of 8.13 reader – Get pdf file from website: “Policies and Procedures”
Sep 3 2008
Experiments
• Major advances in science (e.g. Nobel prizes)
• Learn the art + science of experimental physics– How to obtain good data– How to document your work– How to estimate errors– How to present your results
• As close to real life as possible
Sep 3 2008
Experiments• 26 sessions total (19 for experiments)
– attendance is required– you will need the time
• You will do – 3 intro exp’s
• prep questions• oral presentation + paper for 1 out of 3 (within 10 days after exp)
• graded, but grade not recorded– 4 out of 10 long exp’s (4 sessions each)
• prep questions• oral presentation + paper for each• 2x30min per partnership for oral• 1 public oral in last week of semester
Sep 3 2008
Experiments
• If needed (emergencies etc)– extra time on Fri– signup sheet – never work alone
Sep 3 2008
Papers and Presentations
• Presentation within 10 days of last session for the experiment
• Paper due midnight after the presentation– 10 point penalty per 24h delay
• Any exception must be negotiated with section leader in advance
Sep 3 2008
Grading Scheme• 10% attendance/lab performance
– change ‘lead’ from exp to exp• 10% Notebooks
– graded 3x in semester– info in reader + next session
• 10% prep problems– come prepared, you will need the time– Exp can’t be started w/o prep question
• 40% orals– Use help (Atissa)– 15’ are short– split topic between partners (but not along theory/experiment)
• 30% papers– < 4 pages, due midnight after oral– both partners have to write their own paper

Reading Material
• 8.13 reader – Intro + exp section from web
• Bevington: Data reduction and error analysis ($58) - Required!
• Melissinos: Experiments in Modern Physics - library
• Original papers: See 8.13 e-library on 8.13 webpage
Sep 3 2008
Ethics in Science• Fabrication/Falsification of data
– document everything as you go (Notebook)– complete record of everything you have done, including mistakes
• Plagiarism– never use other work without acknowledgement– mark quotes as quotes– do not import text (from web resources)– Comparison to known values is ok, but not substitution/modification of your data, unless clearly marked
• No tolerance in JLab
Sep 3 2008
Safety
• Electrical safety– be careful– never work alone
• Cryo Safety• Radiation Safety

Homework• Find partner !• Look at web.mit.edu/8.13• Read introduction in reader• Read Bevington chapters 1-3• Start learning LaTex• Decide on intro experiments and experimental line
• Make use of your time now!
