COST WG3

WG3 meeting “Polarization transfer to long-lived spin order and to low-γ nuclei

   The goal of the meeting is discussing methods of fighting relaxation losses in hyperpolarization experiments. One of the common problems in hyperpolarization is storing it for as long as possible to make new applications possible, for instance, in MRI. The common strategies of preserving hyperpolarization are (i) using the so-called long-lived states (LLS) or (ii) shifting polarization to low-γ nuclei (e.g., 13C or 15N), which have much longer T1-relaxation times as compared to typical proton T1 times. Problems of polarization transfer to long-lived spin orders are common for different hyperpolarization experiments, in particular, for DNP, PHIP and CIDNP. Therefore we anticipate that the meeting will be useful for scientists working with different techniques. The gain of having long-lived spin order is two-fold: it allows one to achieve higher levels of polarization and also to preserve it for longer times than it is allowed by standard proton T1-relaxation. Discussions on using LLS and optimizing polarization transfer efficiency are of importance because there are many problems, which are common for various experiments and different hyperpolarization techniques. The scope of the meeting clearly fits to the goals of the COST Action: it will stimulate collaborations and joint research efforts between European groups in hyperpolarization for sensitivity enhancement in NMR and MRI. The scope of the meeting is also related to the 13th Spin Chemistry Meeting, which will be held at the same venue right before the WG3 Meeting. The planned activities are also related to the other 4 WGs of the Action; therefore we expect participants, who are mainly involved in these WGs.

   We are planning to have several lectures, which will introduce the participants in the field and discuss the currently existing problems. It is also planned to have ample time for informal discussion and for planning future cooperations. Early-stage researchers will also have opportunity to present their results and will have preferences in receiving reimbursement for COST.

   The Meeting does not have its own web-page yet; the information will, however, be distributed via the official web-pages of the COST Action (http://www.eurohyperpol.eu) and of the SCM-2013 (http://www.cecp.at/index.php/scm2013).

   Program of the WG3 (Relaxation) Meeting, Bad Hofgastein, Austria, 26-27 April 2013. The meeting will be held right after Spin Chemistry Meeting at the same venue. We are planning to have three Sessions, each containing oral talks and a discussion. Sessions will be dedicated to methodologies of Long-Lived Spin states (LLS) and Polarization Transfer (PT) in hyperpolarization experiments.
