The thermodynamical potential is an important characteristic of the system. We shall obtain the thermodynamical potential in a general case when an external magnetic field H, = const. outside the cylinder is present, and a solenoid with a flux @ ,o,r is introduced into a cavity (here QSO, = nr:H,,,,
## dewar dewar Fig. Plumbing schematic for the automatic transfer system. Valves V2 and V3 are solenoid valves operated at room temperature transfer has been exceeded. After a normal transfer (upper level reached) T2 and T3 are reset and V3 is opened and V2 closed returning the system to the norm
IN some previous papers ~ 3 by this author certain properties of a Nb3Sn hollow cylinder are reported. Additionally, the temperature dependence of the trapped field was investigated as this gives several relations to the Anderson-Kim theory. For conversion of the values to be measured into electrica
THE author has recorded the decrease of a field trapped in a Nb3Sn hollow cylinder with increasing temperature, and found the trapped field to be approximately proportional to (1 -T/Te). In the range of field strength examined, the relation ~z = J~(H + Bo) was followed approximately; the resulting q
