 Sat Mar 28 12:19:21 2020, Ragan, RuiJiu, DAQ, Change of the polarity of Amplifiers 
|
Since last night, the signals from the p-side of all the Si pads were seen as negative on picoscope.
The signals from DSSSD, all n-sides of Si pads and CsI were positive which all are in MSCF-5.
Thus, I and RuiJiu, changed the polarity jumpers of MSCF 1,2,3 and 4(all the four jumpers inside the mentioned MSCF) and now hope to see positive signals from the p-side of all the Si pads. |
|
Sun Mar 29 12:56:02 2020, Ragan, RuiJiu, General, Good positive signals from MSCF
|
As we (RuiJiu and me) changed the jumpers of MSCF 1, 2,3 and 4 yesterday, now we see nice positive signals on picoscope.
Yuri and Sergey are still working on optimising the Tl fragments ! |
|
Sun Mar 29 13:04:32 2020, Ragan, RuiJiu, Runs, run file: 1298
|
The Tl fragments are being stacked (almost ~20 staacks) and tried to store nicely in ESR.
The plan is to see the number of contaminants on the inner detector (CsISiPHOS) after the gas jet is on (Ar gas jet) and minimise this number for different FRS settings !!
P.S. Prayers have magical powers :) :) |
