-Open questions / TODO:
-  * Manual describes filament volts, but GUI shows %.  What is the mapping?
-  * Why can't I get an image in suggested filament range?  Needs replacement?
-    * Note: replacements on order
-  * Do I need to replace column liner?  Can I get them?
-  * BSE detectors works?
-  * EDS works?
-  * What does bias actually do?  Bias on Whenelt to extract electrons?
-  * Why didn't newer software work?  Retry it
-  * Source imaging mode?
-  * Gun assembly is slightly crooked (seal?).  Replace seal?  What caused this?
-Notes primarily from McMaster unit.  Might add some info from mne
-  * "FL DEPT OF LAW ENFORCEMENT"

-  * "I just called RJLee, and discovered he has sold the business and there are no more new PSEM's being sold."
-    * Maybe during a short while?  Aspex continued sales
-  * "R J Lee's SEM group was spun off as Aspex in 1995"
-"By default, we use 10.133.67.1 for the engine and 10.133.67.2 for the console...The IP address of the engine is configured in the file C:\PSEM\WATTCP.CFG"
-  * "These addresses conform to the communications protocol standard RFC-1918 for non-routed IP addresses"
-  * No they don't...
-Calibration: "Geller multi-resolution mag standard"
-  * geller magnification standard
-  * http://www.gellermicro.com/mag_standards/mrs.html
-"On discrete high voltage power supplies, the bias is adjusted via a physical knob on the back of the power supply. On continuous high voltage power supplies, the bias is adjusted by a software knob accessed via the Advanced button on this panel."

-"You will note that there is a n indicator light labeled "PUMP" on the front drawer of the computer drawer which will initially flash.  This flashing indicates that the turbo pump is being accelerated to its maximum speed.  The turbo should normally reach its maximum speed in 2-3 minutes and this light will then illuminate steadily.  Once the pump light is a solid green, no longer flashing, the system is ready to use."
-"Increase the filament knob until you see the value for EMISSION  begin to rise.  This will typically occur around  DRIVE setting of 5-8 volts.  At this time you will also see some indicates of an image on the image screen."
-"Increase FILAMENT until somewhat past the point at which the image brightness no longer appears to increase."
-"Under normal circumstances, the amount of stigmation correction should be rather modest (typically less than 0 mA correction current).  If large correction values are required, it may be an indication that the column liner tube is contaminated and needs to be replaced"
-"The electron source on the PERSONAL SEM users a unique emitter cartridge construction (US Patent 5,376,792) that incorporates a filament and control grid in a single low-cost, pre-cleaned and pre-aligned assembly."
