Introduction to Junior Lab Junior lab web page: web.mit.edu/8.13 Sep 3 2008 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: – Basic research in High-Energy Nuclear and Particle Physics • Find these slides at http://web.mit.edu/8.13/www/handouts.shtml Sep 3 2008 When I’m not in my office, I’m usually here Sep 3 2008 What do we do at LHC ? • Make the Hottest Matter in the Universe – 100.000.000 times hotter than the surface of the sun x 108 Sep 3 2008 CMS experiment Sep 3 2008 The Junior lab team • Dr. Emily Edwards [email protected] – Junior Lab expert • Regina Yopak [email protected] – Junior Lab expert • Scott Sanders [email protected] – Teaching Assistant • Jackie Villadsen – Teaching Assistant • • Cherie Abbanat – help for oral presentations Prof. Gunther Roland Rm 24-504 – Section leader [email protected] x3-9735 [email protected] • Sep 3 2008 For more info, see web.mit/edu/8.13 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 Sep 3 2008 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 How How How to to to to obtain good data document your work estimate errors 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) • • • • Sep 3 2008 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 Sep 3 2008 Schedule QuickTime™ and a decompressor are needed to see this picture. From Sep 3 2008 http://web.mit.edu/8.13/www/calendar.shtml 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 Sep 3 2008 Homework • • • • • • Find partner !
