at 13:00
scrapers in the ESR are moved to block the most outside orbits
E02DS3HG out -> -60 mm
Entry  Thu May 16 16:43:29 2024, Yuri, Accelerator, HHT 
HHT sees radiation from us. We stop for 10 min for them to see the speed with which the radiation level decreases.

Entry  Mon May 20 09:01:14 2024, Yuri, Accelerator, Modify SP magnets 
In attempt to remove double-peak structure, we will modify the SP magnets
START: 9:02
SP unchanged. Other values lead to a worse peak shapes.
Entry  Tue May 21 08:50:06 2024, Yuri, Accelerator, EoB 
End of beamtime!
Request is out.
Scrapers are removed, slits in the TE line removed, ESR is ramped down.

Entry  Sat May 18 01:57:44 2024, Weick, Accelerator, 96Sr isoc setting TEline-ESR-100Mo_96Sr.lpp
We fist verified the ESR after a crash with the 98Zr setting, was fine good resolution, 
then we scaled to 96Sr directly at gamma_t not with shift as before.
E_SIS        = 449.21 MeV/u for 100Mo 38+
