<> ---------- = VIS Meeting = Date: 2025/7/18 10:00-10:35 [[https://zoom.us/j/203743987|Zoom]] Participants: Aso, Ushiba, Sato, Yokozawa, Washimi, Takahashi == Topics == === Type-A === * ACCs for the IP controls. * Evaluating the FLDACC with DGS in ATC ([[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=16646|report]]). Since the DC drift of the feedback signal is very small (<100 count), it is reasonable to add a DC offset in the Coil driver. === Type-B/Bp === * IRM damper for Type-B. * Hirata-san is going to the manufacturing of the parts. * Enclosure for the SG card in an independent box. * Tanaka-san made a prototype box. * IP for Type-Bp. * Started a design ([[attachment:IP for Type-Bp.pdf|draft]]). === Type-C === * Active isolation table for OMC. * The space around the bottom of the chamber is very tight. We consulted with the chamber maker ([[attachment:IMG_0704.JPG|photo1]], [[attachment:IMG_0708.JPG|photo2]]). * Sato-san is designing the new geophone pod. * Investigating the effects of cabling for the geophones ([[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=16645|report]]). * Small Type-C suspensions with mini-GAS. === R&D === == Discussion == * Kakenhi. == Next meeting == * 2025/8/1 10:00-
