We offer upgrade from FeSuMa 1.0 to 2.0 version. The 1.0 in-vacuum part can still be used. Power Supply Unit (PSU) itself, direct communication between PSU and camera assembly, PC and software need to be upgraded. In order to upgrade your system, you would need to send to Fermiologics a couple of plug-in modules of PSU as well as perform upgrade of the software and PC following our instructions.
