SPEAR Beam Integrals (Signals and Reset Procedure)

The following signals are inputs into the BEAMINT program (BEAMINT.C running in the SPEAR control system):

· SPEAR:State

· SPEAR:BeamCurrAvg1S

· OrbInt:RingStopState

· BL01:OpenState

· BL02:OpenState

· BL03:OpenState

· BL04:OpenState

· BL05:OpenState

· BL06:OpenState

· BL07:OpenState

· BL08:OpenState

· BL09:OpenState

· BL10:OpenState

· BL11:OpenState

· BL12:OpenState

· BL13:OpenState

The following integrated beam currents are generated and updated by the BEAMINT program in the spr:BI1/XX1 structure:

· BI1/XX1(1) integrated total current (SPEAR total)

· BI1/XX1(2) integrated run current

· BI1/XX1(3) integrated day current

· BI1/XX1(4) integrated fill current

·

· BI1/XX1(6) integrated total current (BEAMS mode)

· BI1/XX1(7) integrated run current (BEAMS mode)

· BI1/XX1(8) integrated day current (BEAMS mode)

· BI1/XX1(9) integrated fill current (BEAMS mode)

·

· BI1/XX1(11-30) integrated beamline total current (BL01-BL20)

· BI1/XX1(31-50) integrated beamline run current (BL01-BL20)

Resetting the beam integrals

1. STOP the BEAMINT program, process “BEAMINT” running in the SPEAR control system

2. Using interactive CA tools, set the following parameters to ZERO.
   
   

· spr:BI1/XX1(2)

· spr:BI1/XX1(3)

· spr:BI1/XX1(4)

·

· spr:BI1/XX1(7)

· spr:BI1/XX1(8)

· spr:BI1/XX1(9)

·

· spr:BI1/XX1(31-50)

3. Start the BEAMINT program.
   
   
4. Check to numbers going up from ZERO.
