0:00 No beam... MCC working on optics
2:53 Beam in Hall A
3:10 Optics run 7 foil done
3:15 moved to 4 cm dummy target
3:29 moved to 15 cm dummy target
3:43 moved to Tantalu target
3:57 moved to LD2 for production with 5% radiator
Current runs seem to have very few FPP hits, called Jackie and Mark
they are looking into it.
All seem fine to me as far as FPP is concerned (HV,LV, threshold, Gas
Flow )
continuing data taking this way

Pending issues :
FPP efficiency seems to be very low might be due to gas ( maybe )
