Definition of the longitudinal variables used in the numerical model that simulates the contraction of the rod. zscan and zHP are defined in the laboratory system and represent the longitudinal coordinate measured by the encoder of the linear motion system and the real position of the Hall probe, respectively. The z-axis is defined in the reference system of the rod before that the rod contraction is calculated. The z variable will be used to express the temperature profile along the rod. On the left side of the plot the corresponding regions of the cryostat as defined in Fig. 1 are marked. The double waves indicate a cut in sketch. |
