UCSB Hybrid and ARCS Testing Status Update (Week of April 25-29)

This week's testing report from UCSB highlights significant failures in hybrid modules. There were multiple instances of over-counting failing hybrids, with issues such as shorts and damaged components. Notably, three hybrids are repairable, while two failed inspection due to critical defects. The ARCS testing reported no new failures but mentioned ongoing issues with channel performance and the need for confirming cuts on TEC modules. Additionally, there is a focus on software validation and automating data uploads to enhance the testing process.
