Method, system and apparatus for monitoring target tissue temperatures wherein temperature sensors are configured as passive resonant circuits each with a unique resonating signature at monitoring temperatures extending below a select temperature setpoint. The resonant circuits are configured with an inductor component formed of windings about a ferrite core having a Curie temperature characteristic corresponding with a desired temperature setpoint. By selecting inductor winding turns and capacitance values, unique resonant center frequencies are detectable. Temperature monitoring can be carried out with implants at lower threshold and upper limit temperature responses. Additionally, the lower threshold sensors may be combined with auto-regulated heater implants having Curie transitions at upper temperature limits.

An apparatus for synthesizing nanostructures. In one embodiment, the apparatus includes a heating device that defines a reaction zone therein and a susceptor made of a ferromagnetic material with a Curie temperature and placed in the reaction zone, where the Curie temperature substantially corresponds to a temperature at which the growth of desired nanostructures occurs and the heating device is capable of heating the susceptor substantially at the Curie temperature.

A high power high yield target for the positron emission tomography applications is introduced. For production of Curie level of Fluorine-18 isotope from a beam of proton it uses about one tenth of Oxygen-18 water compared to a conventional water target. The target is also configured to be used for production of all other radioisotopes that are used for positron emission tomography. When the target functions as a water target the material sample being oxygen-18 or oxygen-16 water is heated to steam prior to irradiation using heating elements that are housed in the target body. The material sample is kept in steam phase during the irradiation and cooled to liquid phase after irradiation. To keep the material sample in steam phase a microprocessor monitoring the target temperature manipulates the flow of coolant in the cooling section that is attached to the target and the status of the heaters and air blowers mounted adjacent to the target. When the target functions as a gas target the generated heat from the beam is removed from the target by air blowers and the cooling section. The rupture point of the target window is increased by a factor of two or higher by one thin wire or two parallel thin wires welded at the end of a small hollow tube which is held against the target window. One or two coils are used to produce a magnetic filed along the beam path for preventing the density depression along the beam path and suppression of other instabilities that can develop in a high power target.

In the continuous annealing of a steel strip with Curie point (Tc) at an annealing temperature exceeding Tc with the use of a continuous annealing equipment composed of a heating area, a soaking areaand a cooling area, the heating treatment in the heating area is divided into three regions. In the first heating area, the steel strip is heated to below Tc-50 DEG C by radiant heating means by gas heating and / or radiant heating means by an electric heater. In the subsequent second heating area, the heated steel strip is heated to the region of Tc-30 DEG C to Tc-5 DEG C by solenoid coil high-frequency induction heating means. In the final third heating area, the heated steel strip is heated to a treatment target temperature exceeding Tc by radiant heating means by gas heating and / or radiant heating means by an electric heater. Accordingly, there can be attained uniform annealing in the longitudinal direction of the steel strip with Curie point.
