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 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) |

Calibration of new F11 plastic
(see photo)
The new plastic is 1mm thick instead of 0.2mm used last year.
Dimensions:120mm x 100mm x 1mm
HV applied: -1800V
Anode signal connected to Ortec 474 TFA
Gain: 20 x minimum; Int: 200ns; Diff: 100ns; Invert

THIS WAS WRONG! POLARITY OF SIGNALS WAS REVERSED.

Wed Mar 29 11:02:40 2017, PV, Liu, JA, JLT, F11 plastic

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) |

Tue Nov 22 10:22:07 2016, PV, Liu, No current observed when turning on the HV for the D4 Clover
|
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. |
