Nuclear fragments from a gold-gold collision in a Time Projection Chamber

Each colored dot represents an identified nuclear fragment from a gold-gold collision in a Time Projection Chamber; these results are from a project to improve separation of heavier species, by then-undergraduate Kerry Forsythe.

 

 

 

A simulated nucleus-nucleus collision

This hand-cranked movie of a simulated nucleus-nucleus collision was generated by Dr. David Kahana while he was a postdoctoral fellow at the CNR.

 

 

 

A polarimeter

This device for measuring the spin of neutrons (a polarimeter) has 360 degrees of coverage in scattering azimuth, and was developed by Prof. John Watson.

 

 

 

A Time Projection ChamberIn this Time Projection Chamber, trajectories of charged nuclear fragments in a magnetic field are reconstructed from a three-dimensional array of more than two million pixels, using software developed by Dr. Marvin Justice.

 

 

 

Apparatus at the Stanford Linear Accelerator Center

Prof. Makis Petratos played a major role in the design of this apparatus at the Stanford Linear Accelerator Center; it reveals how the spin of the quarks inside a nucleon contribute to the nucleon's spin.

 

 

 

To see an example related to a more recent CNR project (the STAR experiment at Brookhaven National Lab), you may view a rotating 3-D event display of a gold-gold collision at ultra-relativistic energies.
