Live Time and Data Collection q 10/27 – There was a communication error with a chain (crate 1- croce 1- chain 1) • A software reset fixed the issue. Nuruzzaman 4 Proton PMG - 1 Nov 2018
Outstanding Issues from Last Update o Chain 0-4-0 was giving errors and stopping the DAQ ü Replaced all the components of the chain systematically and after replacing the cables seems to fix the problem o Online Monitoring system broke after a power outage with multiple issues ü Replaced the old computer with failed motherboard with a spare computer and replaced the failed disk on spare computer. The system is working again. o Water dripping issue ü Drip seems to slowed down and dried out from bridge area. Still slowly dripping in a different region, but detector is protected by the roof structure. Experts are working on a permanent solution. Nuruzzaman 5 Proton PMG - 1 Nov 2018
