STAR QA Board

["Tang, Aihong" <aihong@bnl.gov>]

Hi, Han-Sheng :

Thanks. I just randomly checked a few from your list, and I don't see this from online plots. For example, see page 29-32 of this file :

https://online.star.bnl.gov/runPlots/24149032.shift.pdf

To me it looks like a digital rounding issue.  For those bins with double entry, could you check if the adjacent bins got zero entry ?  

You have bin width corresponding to one adc count,  what if you double the bin width ?

Thanks,

Aihong

Hi Aihong,

The attachment is the runnumber list I used.

Hi, Han-sheng :

That is interesting. I have not noticed this in shift QA histograms. Could you give me an example runnumber so I can double check it in the JeffPlots ?

Thanks,

Aihong

Dear ShinIchi,

Yes, our histograms have the number of bin per one adc count and this issue should come from the data itself.

Does Aihong know how to deal with this issue?

Best regards,

Han-Sheng

Dear Han-Sheng

I would first like to make sure all your histograms have the number of bin per one adc count, right? 

If you count which bin number have double event entry counts, you might be able to tell which bit 

has problem in the ADC digitization depending on the SMD slat channel. Please talk to the read-out 

electronics experts, maybe Aihong as Prithwish says (or maybe talk to Akio?) for ZDC/SMD. They 

might just need to power recycle the electronics or plug in/out the ADC board etc…

Best regards, ShinIchi
