Part 3: The Vibrating String

By Chelsea Sidrane

Mentor: Dr. Richard Jones

Nuclear Physics:

Put a Quark In itSlide2

GlueX

The goal of GlueX is to study the concept of confinement in those particles that display some degree of gluonic

freedom; hybrid mesons.

Our Part

Of the many components that went into constructing the

G

lueX

setup, we worked on the photon source, specifically, the

mount

for the crystal

radiator

The Principles Behind Our Experiment: Ensuring Radiator Stability

Vibrating WireCrystal radiator must be stable Must be finely tunable to create Coherent Bremsstrahlung

Resonance-

a system’s tendency to vibrate with a larger amplitude at certain frequencies
