Initialize
	Introduction This program covers everything the old INITIA program on the HP could do and then some. The basic operating conditions of the instrument can be set here, as can the user name which will be saved along with every data and setup file that gets created. Some of the parameters selected here are for information only (e.g. the entrance slit setting), while other are very important and functional (e.g. the mass range, which determines what mass calibration setup file to use). Right now there is now visual distinction between informational and functional parameters. Maybe we could change that in the future. The advantage of entering informational parameters correctly in this window is that this information gets saved along with data files. The analysis programs do not ask for this information again each time (as it was the case on the HP).
	Background picture The background picture shows the basic outline of the 3f instrument. Most of the parameter selection boxes are positioned on the background picture where they are located on the actual instrument.
	Source & Polarity Type: Functional pull-down menu. Select the source, primary ion species and primary ion polarity used.
	Primary HV Type: Interestingly only informational. Enter the high voltage (in kV) of the primary ion beam.
	Secondary Polarity Type: Functional pull-down menu. One could argue, that we don't really need this parameter since we only use Cs+ primary with negative secondaries and O- primary with positive secondaries. But in theory, other combinations are certainly possible.
	Mass Range Type: Functional pull-down menu. Select the mass range the instrument is set to. If you are like me (FJS) and always forget how to determine the mass range settings, this pull-down menu also has a help function which displays the following window when selected: This should clarify everything.
	Secondary beam parameters Type: Informational pull-down menus.
	Slit settings Type: Informational enter boxes.
	Detector parameters Type: Functional enter boxes. The values entered here are used by several programs.
	User Name Type: Informational pull-down menu. Select your name from the list of users. Something tells me that it will be difficult to get people to always remember to identify themselves. It would be helpful, though, because the user name gets saved along with every data file. And remember: When the Nobel Prize committee comes to verify the validity of that break-through measurement, you want your name to be there!

	Exit I really don't know how to explain this in any easier words.
