I just had a chance to add the wonderful, Titan training manual to our webpage. If you have not seen it, please check it out. It has full ray tracings of the optics systems and gives many helpful hints such as Gun Lens 8, spot 6 for fine, nanobeam diffraction. I just saved a register using those Gun Lens 6, and spot 6, CA 50 nano diffraction settings. Its never too late to learn something new.

Registration for our continuing ed. class, "Hands on Electron Microscopy" is now open. https://workspace.oregonstate.edu/course/hands-on-electron-microscopy-course

Welcome to the new fiscal year. We purchased a new automated compressor for the Quanta 600 and it works: no more having un expected vents during your Q600 sessions. The Q3D electron column is being rebuilt, new source, new power supply and new aperture controller. The sum of these repairs is over $60k . Come second week of August we expect it to be fully online again for your needs.

We have also implemented a survey. Tell us how we are doing.

Rebecca and Pete still continue to make very good to world class samples and consult and teach students. Pete has now passed the 1000 FIB samples and continues to receive a steady stream of sample making requests , some from out of state. Rebecca, although only here for two years makes wonderful samples that have visible mitochondria, membranes and other ultra structures. The Titan TEM just received a preventative maintenance. And the Gatan, Rio side mount camera continues to be very easy to use and provide 2x to 3x the contrast of the lower Ultra Scan camera. The Ultra Scan camera with its 3 times longer camera length is still most suitable for high magnifications. Note, the Titan is not image or probe corrected.

The continuing education course is back by popular demand and look for it in the Fall.

Our continuing education course, "Hands on Electron Microscopy," is now open for registration. It is a 10 week course one lecture per week. And features 30 minutes of hands on demos every session.

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.

Happy New Year from the EM Facility! We hope that you’ve all had a great first month of the new year!

For today’s announcement, we highly recommend watching a wonderful live demonstration of our FIB FIG system from our facility director, Dr. Peter Eschbach. Check out this neat technique via the link below!

Closed January 15th (Martin Luther King Jr. Day)

The EM Facility will be closed on January 15th for Martin Luther King Jr. Day.

December 22

Announcement's:

  • The EM facility be closed between 25-29th.
  • We've acquired a lovely new table, housing our Ultra Microtome as shown below.

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.

Capabilities

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 roughly approach your area using blue stained microscope slides on the optical microscope. And then coming into your final area of interest with ultimate precision of 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. OHSU is still the lab to go to for Cryo TEM as they have many Cryo TEMs with automated sample holders for looking at your proteins and or small molecules at cryo temperature. At OSU we can however do protein screening with negative staining of your sample on room temperature grids using our very new, high signal to noise ratio side-mount, Rio camera from Gatan. The workflow is first negative staining to make sure the protein is viable then off to OHSU for final pictures onn only the best samples you select with negative stain results here at OSU.

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.
