ETMY Welding Pics
J. Kissel, for A. Bell, T. Sadecki, and D. Sellers While on my way to and from B&K hammering the EY PCAL periscope, I snapped a few publicity photos of Angus, Travis, and Danny who were fine-tuning the alignment and measuring violin modes of the brand new fibers of newly suspended H1 SUS ETMY. Thanks and keep up the good work, gents!

The violin modes were remeasured (with 0.25 Hz accuracy) position (Hz) fibre S/N +X/+Y 504.5 S1400157 -X/+Y 503.0 S1400159 +X/-Y 513.25 S1800486 -X/-Y 510.5 S1800491 as these will shift after in-chamber alignment, we didn't go for higher accuracy. The laser we used was quite noisy and should be replaced before using the kit again.
