The National Biomedical EPR Center provides a variety of services to the EPR community. The most important categories of Service are:
USER GROUPS
To provide hosting for EPR related User Groups
The domain eprbiomed.org has been created to host user groups with specific EPR subjects. These user groups will be hosted on subdomains and allow the managers of the group to have a full range of interactive abilities to provide training and dissemination on their subject (Contact: Jason Sidabras at http://eprbiomed.org/contact )
To provide discussion and dissemination on Finite-Element Modeling.
A website has been created, fem.eprbiomed.org , to allow for in-depth discussions and commmunity training on electromagnetic modeling techniques. Using wiki and bulletin board technology, this user group aims to lessen the learning curve associated with commercial finite-element programs while allowing for technical discussions and exchange of ideas on resonator development. (Contact: Jason Sidabras at http://eprbiomed.org/contact )
To provide discussion and dissemination on EPR Spectra Simulation
A website has been created, spectra.eprbiomed.org , to allow for in-depth discussions and commmunity training on EPR Spectra Simulation techniques. Using wiki and bulletin board technology, this user group provides support for anyone with questions about EPR spectra and how to simulate them. (Contact: Jason Sidabras at http://eprbiomed.org/contact )
To provide spectral simulations using the computer program XSophe.
XSophe is a matrix diagonalization EPR simulation package developed by the Centre for Magnetic Resonance, University of Queensland, Australia, and by Bruker. It is particularly useful for S>1/2 systems, including integer spin systems and spin-coupled systems. Direct values for the inter-metal distances are returned. The program can simulate in both RF perpendicular to H0 and RF parallel modes and at any temperature. A wide variety of line shape models is available, including strains in the Zeeman or zero-field splitting terms. (Contact Dr. Brian Bennett.)
To provide Training in EPR Spectroscopy
Training is available for young scientists for up to two weeks visit. A new type of training for advanced visitors is now offered for one to three months. EPR Training Program
To host a biennial workshop in EPR Spectroscopy
Training workshops on "Principles of EPR" were held in 2004 and 2006. They were developed to offer practical, specific training for students and postdocs new to EPR technology. The next one is being planned.
To make EPR spectrometers available for use.
EPR spectrometers are available to experienced spectroscopists for studies that do not require professional staff assistance.
To obtain 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.
To provide advice concerning synthesis of spin labels and spin traps.
Advice concerning synthesis of spin labels and spin traps can be obtained from Dr. Joy Joseph. Limited quantities of spin labels and spin traps that have been synthesized by Dr. Joseph are available free of charge from the Center on a case-by-case basis, depending on quantities required and quantities available. (Contact Dr. Joy Joseph)
To provide general advice concerning EPR spectroscopy.
Contact any faculty or staff member.
ENGINEERING ASSISTANCE
To assist in making 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. (Contact Dr. Chris Felix.)
To provide 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.
To provide advice concerning EPR engineering
The very well equipped microwave laboratory of the EPR Center is open to qualified users. (Contact Chief Engineer Joseph J. Ratke). Dr. Richard R. Mett has extensive experience in finite element modeling of electromagnetic field in resonators.
