Advanced Laboratory
Summative Assessment
 Final report and laboratory performance (100%)
Advanced Laboratory
24 threehour lab sessionsProf M. P. A. Jones and others
<>COVID19 information:The module PHYS3601 Advanced Laboratory will take place entirely onsite (subject to government rules), with students working individually on experiments, and having greater flexibility over their hours to mitigate against further lockdowns. It will be necessary to place a cap on student numbers taking this module. Even after expansion into all the available rooms (including Level 2 laboratories), the lab leaders have calculated that the maximum number of students that can be accommodated whilst meeting social distancing requirements is 58. If more than 58 students choose this module then the selection of students will occur on the same basis as the longstanding cap for PHYS3581 Team Project, i.e., based on marks in the Level 2 lab module, PHYS2641.
We have had a lot of discussion about this and have had to make some difficult decisions in order to reduce the likelihood that the cap is exceeded, without being unfair on students. In 2020/21:
 The Advanced Lab module will be unavailable to visiting exchange students.
 MPhys students will not be able to take both Advanced Lab and Team Project. This is a change to the information previously published. After much discussion it was decided not to apply this change to BSc students, who will of course be in their final year; MPhys students have the Level 4 project to look forward to.
 For MPhys Physics and MPhys Physics & Astronomy students, we have removed the requirement to take either PHYS3601 Advanced Laboratory or PHYS3591 Maths Workshop. These modules have been added to the list of optional modules. This is a change to the information previously published.
During the module, students will plan and execute an extended laboratory project at an advanced level in either astrophysics, modern optics, high energy physics or condensed matter physics.
Team Project
Summative Assessment
 Oral presentation, Self assessment form, Minute book and Formal report on the project (100%)
Project
25 threehour practicalsProf P. M. Chadwick and others
Team projects involve a group of up to six students working on a Physicsrelated problem in either Michaelmas or Epiphany Term. The problems on which the teams will work will be ‘real' in the sense that there is no ‘correct' solution and no script  they might involve building a piece of equipment, testing a product, designing control systems, etc. Experimental work will be based in the Department, and the problem to be tackled will be set either by members of staff from the Department or by local industry. In the latter case, an occasional visit to the organisation concerned will be required. Whilst students will be under the supervision of a member of staff, they will be expected to evolve their own approach to the problem, organise themselves and work effectively as a team. A short written report and an oral presentation will be required from the team as part of their final assessment. Students must attend a talk at the start of the term in which they are undertaking their project.
Computing Project
Summative Assessment
 Report  including tutorial contribution (70%)
 Presentation  students present a 10minute talk outlining their interpretation of the project, a classic research paper and how they will extend their project. (15%)
 Poster  students will prepare a poster summarising their work on the computer project. Students will then receive feedback on their poster, prior to writing their report. (15%)
Computing Project
1 lecture, 7 tutorials, 7 twohour workshops (optional)Dr C. Zambon
Employing their programming skills gained from the Level 2 module Laboratory Skills and Electronics, students will undertake a computational project in Physics selected from a wide range of problems reflecting the various research interests of the Department. Students will use the program they develop to produce a writen research report at the end of the course. Students will submit their preferences for computing project topic at the point of module selection in June.
