News, Events, & Announcements

July 12th, 2024

We have just confirmed that Gatan will be installing a new side mount, "Rio" camera in the OSU Titan the week of August 5th. This is a CMOS camera with fast frame rates: 20 FPS at full resolution and 200 FPS at 1k by 1K resolution. It also has 4D STEM capability, look for the 4D STEM pack at a later date. Our strategy is to update our Titan TEM with the newest of technology as it becomes available.

We hope that you all have a wonderful winter break! Happy Holidays!!

RELMS , our scheduling system is in full swing and it has really helped streamline our billing. As of April 1st, RELMS was the platform that will be used for booking Quanta 600, Quanta 3D, Titan and Helios.

At this time masks are not required

And as always, we strive to treat all nationalities and ethnic backgrounds with respect and equity.


In addition to an FEI Titan with ChemiSTEM technology, we have staff that are experts in sample preparation. Rebecca excels at ultra-microtome, using glass knives to home in on your area using blue stained microscope slides and then coming into your final AOI with a diamond knife. Pete has created over 1000 FIB lift out samples in 15 years and has 25 plus years experience with mechanical cross section and polishing.

The facility is supported from the Office of Vice-President for Research and the facility's client colleges. The facility is located in Suite 145 in Linus Pauling Science Center.
