We just started data taking. But a few minutes later the main experiment needed to do some adjustements to the beam. This interrupts us for a couple of
minutes... |

Fri May 7 01:49:03 2021, Rui-Jiu Chen, DAQ, Comparison of I_Raw/Q_Raw between different reference level
|
This is a comparison of I_Raw/Q_Raw between different reference level. The range of NTCAP ADC is only 2^15 bit. So signals (I_Raw and Q_Raw) should
not be outside ADC range. It is clear that there is not point outside the ADC range when using reference level -30dBm. |

Sun May 9 20:34:47 2021, Rui-Jiu Chen, Analysis, Comparison of frequency spectrum between 72Ge and other isotope 6x
|
This some preliminary analysis results by using NTCAP data. The IQ rate of NTCAP is 20 MSamples/seconds. I analyzed data files recorded from May 7
17:39 to May 8 2:20. The frequency of 72Ge is bended by 4kHz at the beginning of some injections. In order to check whether this frequency bending is

|
Following Xiangcheng Chen's analysis, I analysed 11 ms time slices separated by 25 ms to see the evolution of the potential isomer across the injection.

Same as before for 5-6 am.
Peak still there, maybe a bit less than before.

Same as before, but for 410 MHz detectors.
Peaks visible in the 3rd-5th slice.

|
After looking through >800 shots from Jul 2nd 21h to Jul 3rd 05h, we couldn't find a single example of a "smoking gun" isomer decay. I.e. I'm talking about
the examples Liliana posted earlier. We did find many examples (roughly 10%) where the ion track spontaneously
disappeared, but this shouldn't be the isomer as there was no frequency shift.

Here's a list of the spectra to look at for the potential isomer, taken btw 21:00 on July 2nd and 6:30 on July 3rd. Two examples attached.
