What I spent most of my mornings doing and how it relates to the experiment

Takeaways What I got out of the internship

What is a Muon Muon is like electron but about 200

times heavier

Decay rapidly into an electron and two neutrinos

Can be seen naturally in cosmic rays

The Basics of Muon G-2 All particles have a property called

spin

Spin vector rotates around magnetic field lines

Ex: Gyroscope will do the same thing but with gravitational field lines

This is called precession

The Basics of Muon G-2

Quantum Fluctuations

Particles popping in and out of existence could affect the precession of the muons

Theoretical Physicists can predict the effects of the fluctuations based on our current standard model

Goals of the Experiment

Get a more precise measurement of the g value (magnetic moment) which can be found using the precession of the particle

If the measured value returned from the experiment is different from the theoretical value, it could mean that there are more particles than we currently know about

Takeaways What I got out of the internship

My Part

Lots of cleaning

My Part Cage Alignment in the bellow

chambers

0.5mm tolerance for all eight dimensions

Actual experiment will measure values to 0.14 ppm

Takeaways What I got out of the internship

Takeaways

More knowledge about particle physics

The importance of precision

Collaboration

You aren’t given a set of steps to follow. You have an end goal and discuss with others on how to reach it

Everyone has a small part to play in the experiment

Python Cosmic Ray Project

Worked on the project with several TARGET interns

Getting started with programming and python

Able to make a contribution to the project
