all The future of DC work

GEO DC workshop June Restructuring of DC and Detector Work for many reasons the DC work was not very efficient in the past site team does 70% of the time DC work only high priority task could be addressed by site team proposal of new structure: re-organize work done at the site → detector team perform the DC work in the search groups and in the detector group ensure the connection between the search groups and the detector group by having a detector group member in each search group increase manpower in detector group

GEO DC workshop June DC work in search groups find artifacts in data that cause problems in the analysis info transferred to detector group, they discuss the problem and improve the detector to avoid artifacts or suggest veto back to search group follow up analysis on triggers request information from detector group on instrumental and PEM channels for trigger time monthly review of the sensitivity and state goals for improvements (frequency domain and time domain) input to prioritization of detector optimization work

GEO DC workshop June S4 – Dates and Goals S4 will start Jan 7th and will last for 4 weeks LIGO goals: Sensitivity goals, inspiral range: H1: 7.5 Mpc L1: 4 Mpc H2: 2 Mpc Duty cycle: 70% individual ifos, 40% triple GEO goal: be factor of 3 for significant frequency range within worth LIGO detector, duty cycle: 90%

GEO DC workshop June S4 – preparation and shifts hardware freeze: Dec 12th control room preparation until Dec 22th LabView control computer operator monitors operator manual search group monitors DC work environment for operator SMS alarms operator shifts 6h – 14:30h, 14h – 22h, no overnight shifts
