 Fri Mar 20 01:11:58 2020, Laszlo, General, Target - beam jntersection, 
|
We have managed to find the target position with the beam by looking at the xray spectra. The trick was that at 10mev we
only have a low increase in the xray rates, so.we went for 400Mev/u where the rate change was dramatic (see in the
picture) |

|
We didmt see any effect on the lifetime if the target is switched on. It is because we use only hydrogen target (but why
is.it so?) |

Fri Mar 20 16:48:00 2020, Laszlo, General, flipped Si shaper output in x and y,
|
Yesterday evening we have found out that the energy signals from the silicon are negative --> wrong polarity of the shapers was chosen while using the jumpers.
Cables coming from the preamp are switched now. --> in the recorded data the X and Y coordinates of the Si strip detector is the other way around!
Hopefully, the left and right side we can judge well... |

Fri Mar 20 16:54:53 2020, Jan, DAQ, BaF OFF downscaled red=32,
|
I introduced a downscaling by a factor of 2^5=32 for the BaF2 during target OFF.
The reason is, that we get a lot reasonable x-ray counts (K-alpha, K-REC) outside target ON phase.
So i want to minimize our deadtime during target OFF, to be able to use the data efficiently if needed.
