Mon Oct 17 05:21:46 2016, Phong, Liu J J, dE detector position and output signal from preamplifier  
|
dE detector is mounted onto the back side of the shielding (attached photo: dE_position.JPG)
The detector consists of 26 strips. In this setup, the detector is devided into 2 parts corresponding to 2 readout channels. Each part consists of 13 strips |

The specification and picture of the dE silicon detector is shown in the attached photos.
The detector has an effective area of 134 x 123 mm and 320 micrometer thick
There are 26 vertical strips. They are combined into 2 readout channels (top and bottom which respect to the orientation of the detector in BRIKEN) |
