Cosmic Ray Test at Vanderbilt University
(2002 August-September)
During the summer of 2002, Vanderbilt team has been testing the prototype
planks using cosmic ray muons. Will Johns took photos of the testing
system including details of the readout system. Below are the thumbnails of
his photo shots.
The cosmic muon ray test system:
Vandy tests 4 prototype planks made of stainless tubes. Over and
under the planks is the trigger system consisting of
scintillators and absorption material, which captures
hard muon particles.
The next four photos shows the system from various angles and altitudes.

Details of readout circuits used for the prototype planks. The larger
chips on the boards are recycled ASD8b amplifiers. We found that
individual threshold control is the key for using the ASD8b. For production
planks, we are using ASDq chips.

In the left photo, a board is shown within a Faraday cage.
The new plank design lets us use a much simpler RF shield than
the one we used in the 1999 beam test.
In the right photo is the board without the cage. |

When the readout system is inserted into a gas manifold of a
plank. Also shown in the photo are readout/HV cables and gas tubes.
