[Sbs_gems] [EXTERNAL] Fwd: Cosmic data for UV Layer and J1

[Gnanvo, Kondo (kg6cq)]

Hi Zeke,
I don’t think it is a big deal. Sean or John will probably fix it quickly
Thanks
Kondo

Hi Kondo,

I am not as familiar with the UV layer mapping. So I'll talk to Sean about this. I'll also do some comparison with the BB UV layer mappings.

Hi Zeke,
That is great. Thanks for these first results.
It looks to me that there is a mapping problem with the UV layer.
Please have a look at the pattern of the 2D hit map. Just a minor issue

Best regards
Kondo

Hi GEM folks,

Attached you will find cosmic data and plots for the UV layer and J1. Taking cosmic data on the UV layer was priority, but we managed to get INFN J1 running as well. We took this data earlier this week. There were about 500,000 events.

Other than a few strips that look not great, it looks like the UV layer is performing fairly well. Maybe Sean, Anu, or John has more to say about that.

In regards to J1, each module on this layer has 2 shorted sectors. Which we see fairly clearly. However, there is a missing APV on the middle module. This was disabled because of connection problems that have since been better  understood. The top module has a partial or almost missing APV, this connection has since been remedied but needs to be checked. So this APV on the middle module is the last major thing that needs to be resolved for J1. There are some strips on the top and middle module that are partial and it needs to be understood if those are bad strips or partially disconnected APVs.

So again the main result for this is the UV layer. But this is also a good starting place for J1. Also take note that the empty plots are simply because this plotting macro was not adjusted for 2 layers instead of 5.

Best,
Zeke
