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 joint together.
Output signal from a high gain channel of preamplifier with 137Cs source is shown in attachment 137CsTest_ac.JPG.;
The white noise is about 2 mV for high gain mode.
We will switch to low gain mode during the experiment.
* note:there is a 200 mV offset due to the characteristic of the preamplifier (see attachment dc.JPG) |
