The LEO SEM has suffered a leak in the V3 valve mechanism, which is used to isolate the important electron source region during sample loading. Before the V3 leak can be fixed, we have taken the LEO off-line and will only use it for special-need projects (such as those that require electroluminescence). All the users certified for using the LEO will be moved to the ULTRA. Please discuss this with Nina or Lei and they can create an user account on the ULTRA. The LEO and ULTRA have the same SnartSEM user interface and certified LEO users will only need a quick training for using the sample transfer mechanism. We thank you for your patience and co-operation.
