WELCOME!

Thank you for visting the Utah State University Luminescence Laboratory homepage! We have been up and running since January 2007. We currently have two RISO TL/OSL Readers and one with a single-grain attachment.

We specialize in the analysis of the optically stimulated luminescence (OSL) signals from quartz sand grains in geomorphological and geoarchaeological applications. We are also equipped to measure Infrared Stimulated Luminescence (IRSL) on potassium feldpsar. Please explore the 'Projects' and 'Publications' pages for examples of internal and external projects that the Lab has been involved with.



LEARN HOW TO COLLECT A LUMINESCENCE SAMPLE

Please visit our How To Collect page for our guidelines and requirements on sample collection.




ANNOUNCEMENTS


Short course: Dr. Tammy Rittenour runs a two-week OSL training course for students and professionals, starting around Memorial Day. Click on 'Summer short course' in the menu to the left for more information.



Tammy Rittenour and Kerry Riley organized a successful 2016 Rocky Mountain Friends of the Pleistocene field trip to southern Utah in mid-October. Please visit our 2016 RM FOP Field Trip page for details from the trip.
