Transcranial magnetic stimulation (TMS) has potential to treat various neurological disorders noninvasively and safely. There has been significant work on coil designs for use on the human brain; however, there are fewer reports on the coil design for small animal brains, such as mice. Such work is essential to validate TMS treatment procedures on animals prior to clinical trials. We report thermal and mechanical analysis of a new small-animal coil system designed to produce focused electric fields resulting in more selective deep-brain stimulation. Thermal and magnetic force analyses conducted at experimental TMS operating conditions are used to determine the mechanical stability of the new coil system. Low magnetic linear attraction and rotational forces suggest mechanical stability of the coil. Small temperature increase over a simulated 60 s TMS therapy session indicates that the coil system operates within safe temperature limits. This coil configuration can be used on mice to stimulate selective regions of the brain to study various neurological disorders, such as Parkinson’s disease. [ABSTRACT FROM AUTHOR]

In the period between August 2010 and August 2011 the SULTAN test facility has been continuously operated, with over one dozen test campaigns. Among the ITER conductors, five Toroidal Field (TF) samples, two Central Solenoid (CS) samples and four NbTi samples for Poloidal Field (PF), Correction Coil and Main Busbar coming from Japan, Russia, Korea and China have been tested with duration of test campaign ranging from two to nine weeks each. Two non-ITER conductor samples are also tested in the same period, a high current NbTi cable-in-conduit (CICC) for the secondary winding of the EDIPO flux pump and a prototype high field conductor for the hybrid magnet of the Radboud University (NL).
