Final results write up in postscript
First we start off with a view of two images of the detector:
A plane radiator image
A sawtooth radiator image
The green, blue and red points are detector pads which have positive signals. The crosses are reconstructed photons and the yellow patterns are Monte Carlo generated expectations of where Cherenkov photons would appear.
You can view pictures of the test beam area here:
|Setting up the equipment||Cleaning up the area|
|Sawtooth radiators separated by a plane radiator||Close up view of the radiators|
|Two cabled RICH modules||View of beam line|
The RICH detector consists of 30 modules each with 8 windows. The detector is displayed unfolded in a flat plane even though it is to first order a cylinder. The active area of the windows is shown in yellow (or orange). The blue rectangles are hits and in the "3-D" view the height of the green line (one for each blue rectangle) is proportional to the pulse height.
