EBSD Detector Down

The ESEM and EDS system are fully functional. However, the EBSD detector is down until further notice. 

I’ve tried solving the problem with Oxford remotely. Unfortunately, we will need to bring a technician on site and will likely need to replace the HKL box. I am looking into the details and will let you know when I have more information.

STEM Titan Themis unavailable from July 18-22

I would like to let you know I’ll be on vacation from July 18th to 22nd and will not be available to run TEM sessions or training sessions during that period of time at the FEI 200kV Titan Themis STEM.

Also, a new rooftop chiller will be installed soon at the STEM lab and the instrument will be unavailable. I’ll let you know when that is going to happen.
