-a.  Switch the POWER SUPPLIES to ON, the yellow light should come on. Switch CHAIN MOTORS to ON, lights 1, 2, and 3 should all come on.  Begin to increase the CHARGING VOLTAGE  while observing the TERMINAL VOLTAGE and the GRID VOLTAGE.  DO NOT allow the GRID VOLTAGE to become more negative than   **-5** VDC.  **NOTE: If you will be raising the terminal voltage to 3.5MV or higher double click the TANDEMWATCH icon on the alphatross terminal monitor.  After approximately 1 minute, the tandemwatch graph should appear on that monitor.  Aleo, check LE tube conditioning by; 1. In the light yellow terminal window, type the command "plot magnet".  This will open a graph that will plot in high sensitivity the LE tube vacuum to watch for tube conditioning.  2. Now, also in the light yellow terminal window, type the command "plotlevacuum".  The plot window should begin plotting a high resolution view of the LE vacuum.  If spikes in vacuum are observed when raising the terminal voltage, stop increasing the terminal voltage and wait until the vacuum returns to the baseline value.  Continue increasing slowly to the desired terminal voltage while continuously monitoring the LE tube vacuum and pausing when increases are seen.  After the desired terminal voltage is reached, the program watching the vacuum can be stopped by entering c/r in the terminal window and the plot can be closed.

 b.	Continue to increase the CHARGING VOLTAGE until you reach the approximate TERMINAL VOLTAGE **__OR__** until you begin seeing any corona current.  If you begin seeing corona current, move the corona points out until no corona current is seen.

+**5.	Dipole Magnet Setup Instructions**
+ **FOR OPERATION IN THE LARGE AND SMALL TARGET AREAS
+**
+ a.  Make sure both "analyzer" and "switcher_hz422" GUI's are turned down to zero amps using the GUI slider.
+ b.  Confirm that the breaker on the beamline near the analyzer magnet is in the down "switch" position.
+ c.  Switch the console "300 Amp ANAL/SWINGER" power supply to the "ANAL" mode using the deflection pushbutton switch.  If in the "SWING" mode press the "deflection" push button switch and wait for it to switch to the "ANAL" (right) mode, then press the "ON" pushbutton switch.
+ d. Confirm that the "SWINGER" Heinzinger power supply is on with the following LED's illuminated:  Red "ON", and Green "Remote".  If Off, Press the "Local/Remote" button to "Local"; then "Stby" then "On"; then "Local/Remote" to "Remote".
+ e. In "Switcher_hz422" GUI window, magnet deflection (left/right) is indicated on the "Switcher Magnet Current" line indicated as beam "left or right".
+ f. The polarity can be toggled using the "Polarity" button located to the right of the "Lock" button.  When the "Polarity" button is pressed, the magnet current will automatically be set to zero and the polarity will reverse.
+ g. Run the slider to the desired current.
+**  FOR OPERATION ON THE SWINGER MAGNET
+**
+ a.  Make sure both "analyzer" and "switcher_hz422" GUI's are turned down to zero amps using the GUI slider.
+ b.  Confirm that the breaker on the beamline near the analyzer magnet is in the up "null" position.
+ c. Switch the "300 Amp ANAL/SWINGER" power supply to the "SWING" mode using the deflection pushbutton switch.  If in the "ANAL" mode press the "deflection" push button switch and wait for it to switch to the "SWING" (left) mode, then press the "ON" pushbutton switch.
+ d. Confirm that the "SWINGER" Heinzinger power supply is on with the following LED's illuminated:  Red "ON", and Green "Remote".  If Off, Press the "Local/Remote" button to "Local"; then "Stby" then "On"; then "Local/Remote" to "Remote".
+ e. Do not go over 20 Amps of Switcher/Anal current in the null mode.  If you do, the breaker near the analyzer magnet may trip and need to be reset to the "Null" position after running the magnet to zero current.
+ f. The polarity can be toggled using the "Polarity" button located to the right of the "Lock" button.  When the "Polarity" button is pressed, the magnet current will automaticaly be set to zero and the polarity will reverse.
+ g. Run the slider to the desired current.
