Academic work

During my four years at Imperial, I have been involved in many experimental and research projects. I have selected a few reports and documents which represent well well my fields of interest and abilities.

Note
All of the work presented was done under supervision of Imperial College staff and remains Imperial's full property. Additionnally, this website is a pale copy of Daniel Winterbottom's own github.io page and all formating credit go to him.

Undergratuate Physics work

MSci Litterature review

I am currently working on my Master's thesis as part of Imperial's CMS search team for the CP state of the Higgs Boson This work is undertaken under Prof. David Colling's supervision and is due to be completed around April 2020. I have produced a preliminary litterature review, sumarising the current state of the field and defining the aims and ojective of my final year project. This review is available for download here and below for viewing.

BSc Project: Laser Eavesdropping

I undertook my Bachelor Thesis under Dr. Mark Scott's supervision. With my partner we wanted to re-visit an old spying technique called laser eavedropping. Used during the cold war this listening method replies on the measurement, via the displacement of a laser beamspot, of windows vibrations. Indeed, voices inside a room carry enough power to make thin glass panels vibrate. We used interference of two beams, one directed towards the vibrating window and a reference laser beam to further increase the accuracy of this technique. After having build a testing setup and develloped the analysis program which converts the displacement measurement back into sound, we have showed that pure frequency sounds can be very accurately reconstructed with this technique. Details of the experiemental method and analyis process are presented in my BSc Thesis below.

Undergratuate Research Oportunity programs (UROPs)

Laser Diffuser for Neutrino detector calibration

This UROP lasted 11 weeks between June and Septemeber 2020. This work, performed remotely was supervised by Dr. Mark Scott and performed in collaboration with Dr. Lauren Anthony (RA) and Dan Martin, then a Ph.D. student in Imperial's HEP. During this time I develloped the analysis program which would Water Cherenkov detectors’ photomultiplier tubes, based on their recording of a very uniform light pulse emitted by a laser diffuser located within the tank. I am very proud of the work I did there: I have shown that the PMTs can indeed be calibrated within 96ps, and probably even more, provided a larger dataset is available. My code can be used with data collected by any Water Cherenkov detector geometry. I have presented this work at the international Water Cherenkov Test Experiment meeting in September 2020, the slides for this talk are available below as well as a written report sumarising the method and results. Both items can be downloaded as .pdf format.

Update to the interferometry experiment

Over the summer of 2019, I worked under Prof. David Colling's supervision on coding a program that would allow for a correction of faulty Linear Stages present in the interferometry undergraduate laboratory. This work has reduced the error on the emission line measurements from 16nm down to 0.1nm and I have demonstrated a stricking example of this resuls with the mercury emission line. My report on the topic as well as the slides for the presentation I gave at the end of my UROP are presented below and again, can be dowloaded.

Teaching and Outreach

As well as being very involved in the Physics side of research, I also value Teaching and Outreach as key activites for a memeber of academia. For the last 5 years, I have uninterruptedly provided tutoring sessions to students aged between 10 and 17 with great feedback, both from the students and their families. Recently, I have develloped a set of Python activities aimed for a student in year 12-13 who would want to learn Python from scratch. These lessons are available here (however they are still in French) and have been passed on to Secondary School Maths Teachers to help them with their own teaching of Python.
