Hi Chao, Maxime and Li,<br>
<br>
As we discussed yesterday, let us try to test/demonstrate the HyCal gain<br>
equalizing<br>
code from the Hall B counting room this afternoon (you suggest the time).<br>
<br>
We will try to mimic the LMS for this purpose, for what we need to do these:<br>
<br>
1) turn on the additional power supplies for HyCal;<br>
2) turn on HV for only a group (48 channels of a lead glass group);<br>
3) identify one channel to be equalized;<br>
4) read dynode signal through the "total sum" ADC and watch it through<br>
the internet<br>
connected scope at counting room.<br>
5) change the gain of this channel by +/- 20 %<br>
<br>
This pedestal readout and subtraction needs to be implemented in this code.<br>
<br>
Let me know what time.<br>
<br>
Ashot<br>
<br>
