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)

*************************************************************

Stopping power calculation (SRIM):
50 MeV/A 40Mg: S=102*1.184=120.8 MeV/mm 
100 MeV/A 40Mg: S=102*0.7129= 72.7 MeV/mm 
(Later: according LISE simulations energy loss of 40Mg  is 88MeV)

What is the energy loss of the "light" particles?

New calibration of F11 plastic

We decided to have both a low gain and a high gain 
for F11 plastic dividing the signal from the TFA 
with a "T" and using in one branch a 20db attenuator (reduction by 10)
and sending to two different DACQ channels.
The gain of the TFA was also reduced to x2

V1A7C3: F11_PL_R (Low gain: ~60MeV)
V1A7C4: F11_PL_L
V1A7C5: F11_PL_R_HG (High gain: ~600MeV)
V1A7C5: F11_PL_L_HG

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)

19:00
We've turned on the High Voltage for the D4 Clover up to ~ 1.5 kV. 
There is no current (0.0 uA) observed in all the channels (crystals) of this clover while the High Voltage is
turning up.
We have turned down the HV after that.
We've checked that the NIM crate power supply for the preamp is On and the HV and peamplifier connections for
this Clover are Ok.
