3D models of the STAR detector, the RHIC accelerator complex, a prototype of an event display for the STAR experiment in SketchUp

I drew the STAR detector and the RHIC accelerator complex in SketchUp. Also, I built a prototype of an event display for the STAR experiment by using SketchUp Ruby API. This page shows image files generated in this project.

The same 3D model as in the previous figure but in perspective. This figure has been often used in presentations at scientific meetings.

Jets at three levels

The following three figures illustrate jets defined at the three different levels. These figures have been used several times in scientific meetings, e.g., the slide 4 of a presentation at APS 2010 .

A high-pT back-to-back dijet event at the detector level. The solid trajectories indicate TPC track measurements while the lego blocks indicate energy deposited in the BEMC towers.

Jet Patch Trigger

icon

The locations of the twelve jet patches of the BJP1 trigger in Run 6. The size of a jet patch is 1.0x1.0 in the η-φ coordinate system. Each jet patch contains 400 BEMC towers. This figure was used in Phys. Rev. D 86, 032006 (2012) (DOI: 10.1103/PhysRevD.86.032006 )

 

Event Display

I developed a prototype of an event display for the STAR experiment using the SketchUp Ruby API. This prototype was used in jet analyses, in particular, in establishing a jet definition and determining background events.
