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

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

– Get pdf file from website: “Policies and
Procedures”

Experiments
• Major advances in science (e.g. Nobel prizes)
• Learn the art + science of experimental
physics

obtain good data
document your work

• As close to real life as possible

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
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

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

Safety
• Electrical safety
– be careful
– never work alone
• Cryo Safety
• Radiation Safety
