The Laboratory SBT (“Systemes à Basse Température”) has studied Fundamental Turbulence at High Reynolds Numbers for many years. Different experiments were performed, which allowed to study high Reynolds Number flows, and also to compare these (normal helium) turbulent flows with superfluid flows driven under the same conditions. First section describes the interest of hot wire anemometry to characterize the turbulent flows. Hot wires were used already in Hejet, and more recently in SHREK. However, the hot wires should be calibrated, which is not always possible  in situ.  Therefore, we built a facility dedicated to the test and calibration of hot wires. This original facility is described in second section; instead of having a fixed hot wire in an incoming flow, which is the usual situation for hot wire calibration devices, the hot wire to calibrate is installed on a support part, which can be rotated in a fluid at rest. In order to calibrate the hot wires in the same velocity domain as in the SHREK and Hejet experiments, the support of the hot wire can reach velocities of a few meters per second. The first results obtained with Hecal are presented in third section. Fourth section describes the future work to be performed in the CEA facilities.
