DTU Nanolabs Tecnai T12 is a transmission electron microscope (TEM) used for performing both conventional imaging and diffraction, energy dispersive X-ray spectrosocopy (EDS) and cryo experiments. It is a versatile instrument, ideal for studying a wide range of general and advanced materials, soft matter, composites, etc. <br /> | |||
The Tecnai T12 is a transmission electron microscope equipped with a thermionic electron source with a Lab6 filament and acceleration voltages that can vary between 80-120 kV. It has the FEI bio-twin pole piece with a pole piece gap of 11 mm (Cs about 2.2 mm). This gives the microscope a resolution @ 120 kV of above 4 Å in TEM mode. Additionally, it is equipped with permanent cryo plates, which makes it ideal for cryo experiments.<br /> | |||
On the analytical side, the microscope is equipped with an Oxford X-Max 80T SDD X-ray detector for Energy Dispersive X-ray (EDS) spectroscopy. For imaging, the microscope is equipped with Gatan Orius SC1000 CCD (4008x2672 px).<br /> | |||

== Sample holders == | |||
The default specimen holder for the T12 is called Single-Tilt (FEI ST) and it is always present in the microscope room. | |||
[[File:ST holder.jpg|300px]]<br /> | |||
The lab has also other specimen holders used for various application e.g. heating (furnace and MEMS-based), cooling, biasing and tomography. For information on the various specimen holders see [[LabAdviser/314/Microscopy 314-307/TEM/Sample Holders|HERE]] | |||
== Who may operate the Tecnai T12 == | |||
Anybody in need of a TEM microscope is welcome to apply for access to our facility by submitting an [https://www.nanolab.dtu.dk/use-nanolab/use-of-our-facilities Access Request Form ].Shortly after your ARF has been received you will be contact by the microscopy support team in order to set up a meeting to further discuss your application.<br /> | |||
In order to be authorised to use the Tecnai T12 you must complete the Tecnai training with consists of a theoretical lecture and 3 practical sessions of 4 hours each.<br /> | |||
Due to the similarity of the basic operations on a Tecnai TEM and a Titan TEM, a Tecnai trained user can receive additional training and progress in using a Titan TEM.<br /> | |||
When you have demonstrated a high level of familiarity with the Tecnai TEM you will be authorized and allowed to book it via our booking system called LabManager.<br /> | |||
== Booking == | |||
Booking on the T12 is done by the users in accordance to the booking rules. At the moment, there are NO booking rules on the T12. | |||
