Quad scan

1.) deliver 165 mA peak current to FC with all Quads off Ouput corrector off (H2=0,V2=0) 2.) Use Q1-Q3 to make smallest spot on the OTR

3.) Use Output corrector to center beam spot onto OTR. Record transmission.

Quad scan using Q4

Do quick quad scan with analog camera


Install digital and shielding
