==== Report for week of 4/9 ==== * We packed away the SRM SF and BF. * After several failed attempts with one secondary prism, Mark finished the SR3 prism/magnet gluing. * Tanioka-kun built two IRMs (less OSEMs). * Enzo built an RM. * Kozu-kun and Enzo calibrated one set of 6 IM OSEMs for SR3. (6 OSEMs for SRM remain to be done.) * Hirata-san aligned the assembly frame, installed the interface bars and IM ring, and installed the IM. |
==== Report for week of 6/11 ==== * Enzo redid the SR3 BIO connections to match the now-working BS setup. He also fixed PR2, which had a similar problem. * Enzo replaced LPCDs with HPCDs in the SR3. * Hirata-san installed the cable clamps and Cu segments on the SF cap. * Hirata-san and Kozu-kun continued tuning the filter in PI #3. Unfortunately it seems to be rather weaker than expected, and we have not found a compression setting that gives a good frequency. We may have to use tricks like reducing the number of Cu segments on the SF (or using Al ones) to save weight. * Mark, Enzo and Terrence suspended the BF/... section from the SF, and got it aligned for TFs. |

Report for week of 6/11
- Enzo redid the SR3 BIO connections to match the now-working BS setup. He also fixed PR2, which had a similar problem.
- Enzo replaced LPCDs with HPCDs in the SR3.
- Hirata-san installed the cable clamps and Cu segments on the SF cap.
- Hirata-san and Kozu-kun continued tuning the filter in PI #3. Unfortunately it seems to be rather weaker than expected, and we have not found a compression setting that gives a good frequency. We may have to use tricks like reducing the number of Cu segments on the SF (or using Al ones) to save weight.
- Mark, Enzo and Terrence suspended the BF/... section from the SF, and got it aligned for TFs.
