Cabling is done. * Height somehow changed from the last week to this week. We are fixing it, but it seems to change daily. * Alignment will be roughly adjusted today, and first contact will be removed today. * Circuits and connection to digital system are done. We started matrix tuning. * Viewport of Oplev is missing. It will be placed the next, but we need indium. == 2. ETMX pump-down == * See the check list. |
