9. 30-Aug-00 W.A. Zajc Where We Work Almost all activity at Brookhaven National Laboratory u Previously: “Fixed-target” experiments at BNL: o E859 (W.A. Zajc, co-spokesperson o E866, E858 o E910 (B.A. Cole, spokesperson) u Currently: PHENIX Experiment at RHIC (W.A. Zajc, spokesperson) R H I C STAR PHENIX AGS Tandem Route 25 William Floyd Pkwy. BNL Campus PHOBOS BRAHMS Booster

10. 30-Aug-00 W.A. Zajc Intersection points Close-up of intersection point What is RHIC? l RHIC = Relativistic Heavy Ion Collider l Made of two intersecting rings u 2.4 miles around u Two counter-rotating beams u Intersect at six locations

11. 30-Aug-00 W.A. Zajc l We have a theory of the strong interaction: It works well except when the interaction is strong! Why is RHIC? l To understand fundamental aspects of the strong interaction: u Where does the proton get its spin? u How does nuclear matter “melt”?

12. 30-Aug-00 W.A. Zajc Is RHIC Working?

13. 30-Aug-00 W.A. Zajc What is PHENIX? PHENIX u Pioneering High Energy Nuclear Ion eXperiment u The largest, most sophisticated heavy ion experiment ever built u A major piece of civil engineering u A showcase for Nevis Labs’ special talents in developing sophisticated electronics u A precision microscope, thermometer, etc. with which to probe the new states of matter that will be formed at RHIC.
