| * Reduce the size of the breadboard to 800 mm dia, and add RF PD layout for REFL [Ryan] * Slightly update the layout to have more space between AS RF beam and OMC REFL RF QPD [Huali] * Check IFI chamber layout if POM2 the beam is hitting the center of POM2 [Michimura] |
* Avoid 0.5 inch optics and make them 1 inch, and upload current layout to JGWdoc [Ryan] * DONE [[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=16644|JGW-G2516644]] * Design in-air REFL layout by following current design [Ryan] |

Zoom meeting
Minutes
- AS (Huali)
Updated layout in JGW-G2516616
- We will need to add a fast beam shutter between OFI and OSTM at some point
- REFL (Ryan)
- In-vac layout complete. Fits in 800 mm dia.
- Set tilt of all RF PDs and RF QPDs to 15 deg, following LIGO layout.
- To make CAD drawings based on these layout...
- We will need to design a beam diverter and RF QPDs based on LIGO design
- We will need to design pedestals, periscopes, optical bench etc.
For 210 mm heigh optics, follow JGW-D1503916.
For 4 inch heigh optics, Thorlabs BA1/M for the base and 20mm dia. posts.
A/I
