Service activities at the National Biomedical EPR Center are diverse in nature and include:
Provision of engineering drawings, advice, and, in some cases, hardware;
Assistance with construction of EPR and sample-handling equipment;
Carrying out of HFSS simulations to assist in resonator design;
Provision of novel spin traps and synthetic methodology;
Recording and analysis of EPR spectra at 1-35 GHz;
Providing advice regarding commissioning, testing, and maintaining of cryogenic equipment;
Matrix diagonalization computer simulations;
Performance of rapid-freeze quench spectrokinetic experiments.
These activities involve the entire complement of faculty and staff at the Center and often graduate students.
To apply for Center Services contact Candice Klug directly at firstname.lastname@example.org or contact the appropriate staff member for the service categories described below.
General Advice Concerning EPR Spectroscopy
Contact any faculty or staff member.
Training in EPR spectroscopy and related techniques.
Training is available for young scientist for up to a two-week visit, with some financial support. A new type of training for advance visitors is now offered for one to three months. (See the Training Section)
Training workshops in EPR spectroscopy.
Principles of EPR Training Workshops were held in 2004, 2006, 2009 and 2012. They are developed to offer practical, specific training for students and postdocs new to EPR technology. Future training workshops will be held. Contact Candice Klug at email@example.com.
- EPR Spectrometer Availability
EPR spectrometers are available to experienced spectroscopists for studies that do not require professional staff assistance. Available EPR spectrometers. Contact Candice Klug at firstname.lastname@example.org or the faculty member with whom you have previously worked.
- EPR Spectra from Samples
EPR spectra from samples submitted by mail will be obtained if the study is routine. Otherwise, a visit to the Center is more appropriate. Contact Candice Klug at email@example.com or the faculty member with whom you have previously worked.
- Engineering Assistance
Specialized Pieces of EPR Equipment
Assistance is available in making various pieces of specialized EPR equipment, including not only advice but also in many cases mechanical drawings. Examples include the following:
- Numerous loop gap resonators or cavity resonators as described in our papers (Contact Dr. James S. Hyde)
- Holder for TPX capillaries in an Eppendorf centrifuge tube
Technical Information for Maintenance of Varian EPR Spectrometers
Center engineers, as well as Dr. Hyde, have extensive knowledge of Varian EPR spectrometers. They may be able to help individuals locate parts. If there is a technical question, contact Chief Engineer Joseph J. Ratke.
The very well-equipped microwave laboratory of the EPR Center is open to qualified users (contact Joseph J. Ratke). Dr. Richard R. Mett has extensive experience in finite-element modeling of electromagnetic field in resonators.
