Minutes

We had a short meeting. Jack reported that the SBS magnet tripped at 90% and likely required replacement SRCs. This might take a while since he doesn't have any onsite. Alex says the DAQ is working. Holly says the alarm handler is working but folks should let her know if more things need to be added. Simona is continuing to perfect the run plan for bringing beam safely and establishing the raster. The laser system has not received its final inspection and approval. Likely Monday. Jack will continue testing the magnets. When he is done, Todd and co. will continue preparing the target ladder. Tuesday we are expecting to have survey of the target.
