Important milestones
- 2022 May 2: high-power laser beam dump test
History
- August 19, 2022: potentially measured non-linear signal (http://physics-elog.slac.stanford.edu/facetelog/show.jsp?dir=/2022/33/19.08&pos=2022-08-19T23:59:00, http://physics-elog.slac.stanford.edu/facetelog/show.jsp?dir=/2022/33/20.08&pos=2022-08-20T06:45:00)
- August 13, 2022: first collisions! (spatial overlap with knife-edge scan, verified anticipated t0 with EOS, found timing signal on YAG which confirmed temporal & spatial overlap with RP attenuator in, went to full-power mode, compensated timing, saw gamma1 signal in timing scan, saw low-energy scattered electrons on LFOV and EDC) http://physics-elog.slac.stanford.edu/facetelog/show.jsp?dir=/2022/32/13.08&pos=2022-08-13T23:50:00, http://physics-elog.slac.stanford.edu/facetelog/show.jsp?dir=/2022/32/14.08&pos=2022-08-14T03:45:46
- August 6, 2022: practiced knife-edge scans for spatial overlap verification, attempted to see linear Compton scattering (not enough laser intensity with RP attenuator in): http://physics-elog.slac.stanford.edu/facetelog/show.jsp?dir=/2022/31/06.08&pos=2022-08-06T23:59:00 http://physics-elog.slac.stanford.edu/facetelog/show.jsp?dir=/2022/31/07.08&pos=2022-08-07T11:00:00
- August 2, 2022: recovered laser spot, aligned YAG target, practiced spatial overlap, couldn't find relative timing signal (http://physics-elog.slac.stanford.edu/facetelog/show.jsp?dir=/2022/31/02.08&pos=2022-08-02T23:50:00)
- July 26, 2022: recovered laser spot, couldn't align YAG (http://physics-elog.slac.stanford.edu/facetelog/show.jsp?dir=/2022/30/26.07&pos=2022-07-26T22:30:08, http://physics-elog.slac.stanford.edu/facetelog/show.jsp?dir=/2022/30/26.07&pos=2022-07-26T22:00:00)
- July 10, 2022: attempt to recover laser alignment remotely (http://physics-elog.slac.stanford.edu/facetelog/show.jsp?dir=/2022/27/10.07&pos=2022-07-10T23:59:44)
