Dear all,
Despite all the efforts we could not finish work in the hall. Work will be continued tomorrow morning.
Shift for owl tomorrow is canceled. The day shift tomorrow will start at noon.
Regards, Stepan

But unfortunately, we still have issues with the vacuum, and some work remains on the SVT. We plan to close and start beam commissioning tomorrow during the swing shift (one day delay).

The remaining work includes finishing with SVT cooling connections, installing the target, and closing the vacuum chambers. After that, we can connect the vacuum pipe through the first Frascati and pump down the system. So far the main issue is to get a good vacuum upstream of the chicane. Other minor things are installing the hodoscope PMTs (ongoing), finishing the downstream beamline (ongoing), and finishing positioning the ECal (within the next hour).
