How to Rotate the Holding Field

• Figure out what the field angle is and what you want it to be.
• Alert your shift leader that you are rotating the holding field.
• If the beam is on, Call MCC and tell them to turn the beam off. Wait for them to tell you it is off.
• Turn off all lasers according to the 'How to Turn On and Off Lasers' section.
• The Target Operator Control Panel should be running on the target control computer. If not, double click on the 'TO Screen.vi' shortcut in the middle of the Windowns background.
• Click on the 'Rotate Holding Field' button on the left. A new panel should appear on top.
• At the top there is a pull-down list of angle changes. Click on the arrow on the right of the list and select the angle change you want to make by clicking on it.
• Make sure this is the change you want to make.
• Click on the 'Go' button
• The program will ask you to check to see if the standby light on the Latch FG is lit. This function generator is located directly above the target computer and is labeled. The light is on the 'OUTPUT' panel and is labeled 'STANDBY'. Make sure it is off. If its on, you need to turn it off. Put it in local mode by pushing the 'LCL/P.SET' button on the 'STATE' panel then simply use the right arrow on the 'OUTPUT' panel to move the light to one of the wave function (the fourth from the left is a good one, its automatically reset by the computer so as long as the FG is not in 'STANDBY' it will work fine).
• The program will then bother you about the lasers again. Make sure they are off.
• The program will then set up the function generators for rotation. Then it will rotate the field. This takes about 5-10 minutes.
• The VI will tell you when it is done. Click 'Exit'.
• Make an entry in the Target Logbook that the field was rotated and what angles it was rotated from and to. Also make an entry into the halog.
• Turn the lasers on according to the 'How to Turn Lasers On and Off' section.
• Alert the shift leader that the field has been rotated.
• If applicable, ask for the target to be unmasked and to turn the beam back on.
