Cold Neutron Triple-Axis Spectrometer
CTAX | CG-4C | HFIR
- Shipping address for samples: Please visit the ORNL User Facilities Sample Handling and Shipping page for the correct address. Do not ship samples directly to the CG-4C instrument team members.
- Access to CG-4C data: Data files are accessible at the instrument using the Spectrometer Instrument Control Environment (SPICE) data acquisition system. Data may be accessed remotely from a secure server using the HFIR Graffiti software.
- Sample Environments: CG-4C can accommodate a wide variety of sample environments. For more information, please visit the following page: https://neutrons.ornl.gov/sample. Once you are notified of an approved proposal, please update your impossible dates in IPTS as soon as possible to ensure that they are accommodated in our instrument schedule. Note that there will be limited scheduling flexibility for experiments requiring sample environments other than closed cycle refrigerators.
- Neutron alignment station (CG-1B): If you need to align a single crystal with neutrons before your CG-4C experiment begins, please email the CG-4C instrument team well in advance so alignment time can be reserved for you on CG-1B. Note that we have a first come, first served scheduling system for this instrument. Also, let the instrument team know if you are experienced with sample alignments or if you will require significant assistance.

a. As a condition for performing nonproprietary research, the US Department of Energy requires users to publish results from their research. Authorship of publications based on research from these facilities should reflect the normal considerations of recognizing collaborations. It is also important to take into account the considerable efforts of the instrument scientists in their role of designing, constructing, and/or operating the instrument and related facilities. Results are typically published in peer-reviewed journals, proceedings, or presentations at technical conferences. Proprietary users are not required to publish.
b. Credit line: The CG-4C Cold Neutron Triple Axis Spectrometer should be acknowledged with this required statement:
This research [or, A portion of this research] used resources at the High Flux Isotope Reactor, a DOE Office of Science User Facility operated by the Oak Ridge National Laboratory
c. Publication Record: Please submit publications, thesis, patents, etc., to PuSH (Publications of SNS and HFIR) to assist us in recording your contribution. Both the credit statement and links to PuSH are on the Neutron Sciences Publications website.
