PHYS2320 Computing 2 2019-20 Assessed Coursework
Coursework
1 Introduction
This document will give you all the details for the main project part of your Computing 2 Assessed
Coursework. This project carries a total of 85% of the credit for the overall module (unless
otherwise advised by Dr Burnell). Please remember that marks are awarded for the structure,
style, and robustness of your code as well as for its functionality. Please see the mark
sheet and grading criteria on Minerva for details.
You are strongly advised to read the whole of this task sheet thoroughly as you may
find information in the later sections that is helpful to completing the assignment.
1.1 Deadlines
You should submit your work via Minerva by 2pm on Thursday 26th March 2020. Late
submissions will incur the standard University penalty of 5% for each day and part of day that it
is late.
Please contact the Physics and Astronomy Taught Student Office if you require an extension
due to mitigating circumstances.
We hope to return a feedback sheet to you around the end of teaching in Week 11 of the semester.
1.2 Weekly Reports
There are no set times when you must work on the coursework, unlike in semester 1, attendance
at the timetabled sessions us not compulsory.
You are, however, required to complete a short weekly online progress report from
the start of semester 2 until the deadline to hand in the work. Completing the weekly
progress reports carries 10% of the marks for the assignment.
To complete your weekly report, you must go to the module website: https://phys2320.
leeds.ac.uk/ and click on the Progress Report link and complete and save a report. You
must do this at least once each week between 6am Monday and 10pm Friday.

1.3 Time Allocation
Although you are not required to attend the lab sessions, there will be demonstrators available
in the Computer lab clusters between 11am and 12am each Tuesday and Thursday and Dr Burnell
and/or Dr Barker will be available either in room 8.310 on the Physics Research Deck, or
their offices (8.303, 8.307) 1pm-2pm on Tuesdays and Thursdays for first-come, first-served
surgeries. You can also ask questions on the forums on Minerva and Dr Burnell will aim to answer
questions posted there within two working days.
To avoid answering the same question repeatedly, only questions which are confidential in nature,
such as mitigating cirucmstances – ill health, family bereavement and the like will be dealt
with by email. Emailed questions that are not about confidential matters will not be answered
via and should be posted on the forums so that other students can beenfit from the answer too.
Questions can be posted anomyously on the forums.
It is expected that this assignment will take up to 60 hours of programming time over the semester.
1.4 Overview
In this assessed project you will analyse some simulated data using Python code and prepare a
simple report that gives your key results and describes how your code works. You will submit
your code, report and a data file via Minerva.
Your code will be assessed first of all by an automatic checking script that will test whether
your code works with both the data file you submit with your code and with a second data file
of standard data. The testing program checks whether your code produces results in the format
specified here and whether the results match both the known correct answers and also match
results from a reference solution.
Your code and report will then be assessed by one of the module demonstrators who will grade
it for structure, style and documentation and whether your report describes the code you have
written accurately.
2 Background
The tasks in this coursework are based around the analysis of X-ray diffraction spectra. You
will be provided with simulated data sets representing diffraction from a sample of AuxCu1−x
metal alloys measured using a synchrotron radiation source such as the Diamond Light Source
at Harwell.
You will know from Physics 2 that a series of lattice planes with a spacing d will diffract coherently,
giving a maximum in intensity, if the Bragg equation is satisfied.
λ = 2d sin θ (2.1)
where λ is the wavelength of the radiation, and θ is half the angle between the incident and
diffracted beams of radiation.

For a crystal with a cubic lattice, the inter-plane spacing d can be related to the Miller Indices
(hkl) and the lattice parameter a with:
