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.</div><div><br></div><div>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. <br></div><div><br></div><div>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 betterĀ 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.</div><div><br></div><div>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.<br></div><div><br></div><div>Best,</div><div>Zeke<br></div></div>
