Run Info

• With Raster Off, the Maximum Beam Current on Multi-Foils, I_max = 10uA
• With Raster ON, the Maximum Beam Current on Multi-Foils, I_max = 40uA

LHRS optics runs

Step L1: Procedure with Sieve-slit

Run number	Target	Sieve	Raster	Ebeam [GeV]	P0 [GeV/c]	θe [deg]	Comment
	Multi-foil carbon	In	Off	4.3	3.8	17
	Multi-foil carbon	In	On	4.3	3.8	17
	Multi-foil carbon	Out	On	4.3	3.8	17	Taken during the Production-Run
	Multi-foil carbon	In	Off	4.3	3.0	17
	Multi-foil carbon	In	On	4.3	3.0	17
	Multi-foil carbon	Out	On	4.3	3.0	17	May not take this

Step L2: Delta Scan with Proton Elastic

• Note: Depending on the beam-time and quality, this run may be pushed to the Jan./2018 Runs.
