The work is only of value if it has been carried

out properly such that the results are:- • accurate/reliable - i.e. correct techniques• reproducible - i.e. no unknown variables• convincing - i.e. procedures accurately documented, data correctly analysed, and results published appropriately.

This can only be achieved by good

laboratory practice - by being professional.

Objectives

[a] You will acquire specific skills, e.g. learning about electronics, setting up optics, computing techniques.

[b] You will acquire general skills, e.g. keeping records, assessing uncertainties, analysing data, writing reports.

[c] Deeper issues, e.g. working together, organising your time, becoming a professional.

[d] You will learn some new physics!

Introductory sessions• You will be allocated to a lab group

– a,b,c (Mon/Tue) or x,y,z (Thu/Fri)– May appear on timetable as e.g. Lac, this means

Lab for groups a, b and c.

• Monday is Mb Oz Ea. Each group will do: – 1×3 hour session in computing suite

(measurements and errors)– 1×3 hour session in optics lab– 1×3 hour session in electronics lab

• Learn basic lab skills. No assessment!

Level 4

Demonstrators

Demonstrators are there to help you. This is their main job.

If you have a problem with the script or the apparatus or computer, or your results, ASK FOR HELP - any demonstrator will do.

You will have one demonstrator specifically assigned to you. He/she will check your lab book to make sure you are keeping the right sort of notes, and will also assess your work and mark your report.

In the laboratory you will need:-

1. The laboratory timetable 2. Your handouts, “Introduction to First Year Laboratory”, “Measurement & Errors Summary”, “Notebook Guidelines”, “Plagiarism Guidelines” 3. Calculator 4. A sturdy laboratory notebook. A ‘pad’ of paper is not acceptable! 5. The experiment script 6. A partner for the optics - allocated at the start

The PC cluster on level 3 is used for the Computing ‘experiment’.

In addition there are some stand-alone PCs in the laboratory for graph plotting and data analysis.

You will all have been introduced to the PC cluster by the time the laboratory starts. Martin Morris manages the cluster and would welcome any feedback on the system.

There are very strict rules on the misuse of computers which you should not take lightly.

Assessment[a] General Assessment• Relates to how well you are working in the laboratory. • Your demonstrators award the mark in consultation with the Head of Experiment. Mark is multiplied by your fractional attendance. • If you have to be away for any reason, see either Dr. Ray Murray or myself. • Illness requires either a Doctor’s note (>2 consecutive sessions) or a ‘self certification’ form given to the lab office, or Dr. Murray or myself.

Try to give a meaningful description of the reason for your absence.

[b] Report AssessmentI will cover this you later – presentation in LT1

Assessment Grades

You will receive a percentage grade. These correspond to the following degree categories:-

>70% First class

60-70% Upper second

50-60% Lower second

40-50% Third class

<40% Failure of laboratory

All marks count towards your degree and, as such, the normal (tough) rules on cheating apply.
