Abstract

I do not usually write about my own scientific work, but I’m going to make an exception for this column and tell you about a physics puzzle and how we solved it. Back in 1991, almost a decade before the facility actually went into operation, I wrote a column ("RHIC: Big Bangs in the Lab", Analog, June 1991) about the Relativistic Heavy Ion Collider (RHIC), a large accelerator project that was then in the early stages of construction. The column was written a few months after I joined what is now called the STAR Collaboration, a group of physicists (now numbering 577) who ultimately built a large "time-projection chamber" detector for tracking and making measurements on the charged particles produced in RHIC collisions.
