Dear Colleagues,

More updates in EM Facility below:

Nova NanoSEM 230 high-resolution SEM has been installed and signed-off, and will be ready for use from the beginning of next week. Functions are summarized below:

1. 1 nm Resolution at 15 kV, less than 1.6 nm at 1 kV; 2. High vacuum mode (conductive sample) and low vacuum mode (non-conductive samples); 3. X-Ray EDS chemical analysis (EDAX, Inc); 4. Electron decelerating to several hundred volts, reduce the landing velocity of electrons on samples – to reduce beam damage, and charge effect for non-conductive samples; 5. Everhart-Thornley detector (ETD) for SE and BSE signal detection from outside of column, suitable for working distance > 5mm; 6. Through-Lens Detector (TLD) inside the column (immersion mode), for detection of SE and BSE signals, suitable for working distance < 5mm and high resolution imaging; 7. Low vacuum high contrast detector (vCD) for low kV image, especially when electron decelerating function is used;

In order to make training smoothly, we will start training to users who have already authorized to use either Quanta 3D, or Quant 600F.

The installation of Titan 80-200 high resolution TEM will be started next week or the following week. Philips CM12 STEM will be decommissioned by the end of February, no later than end of March, depending the progress of the installation of new TEM.

More are coming!
