h1. October 28th 2021 * Updates ** VMM ***issue with connector tolerance - solution using fixed and floating connectors ***send power board end of week ***gave VMM Eval board to Xinzhan ***Got 2nd VMM, working on software to ***Radioactive source area ***ArCO2 gas ***can look at signal from VMM ***Friday to Monday in UVA - to setup X-ray ***VERSO : could use ** APV ***working in Hall A 5.2 KHz 6 samples ** FADC *** driver for ethernet adapater not loaded correctly - and should work - might need new kernel ** VTP *** New firmware is ready for multicrate ECAL trigger testing (fixed a bug with it early this week) *** Trying to get solidvtp1 and 2 root mounts to be same as Hall A VTPs. solidvtp1 seems to mount it now, solidvtp2 doesn't *** These VTPs we're (kernel) crashing often before, so this is why I want to run the same mounts as the Hall A VTPs (where we don't see this). Not sure if the issue will be gone after this mount change - if not I'll check if Bryan can figure it out and probably we can run as-is if we can at least get the VME crates online so we can remotely power cycle to recover *new funding request **will test radiation hardness next week **new bPOL supply, GBT ordered **might need to switch to lpGBT and VTRx+ **TMR commercial software - evaluate cost **filtering of VMM : ferrite saturates - air core inductors are big - might be better if far from supply - could use linear regulator - **TDIS : flex circuit board to get signal out
