| 1. A magnetic resonance probe head, comprising:
a detecting device having at least one antenna system which is cryogenically cooled by a cooling device;
a preamplifier housing which is spatially separated from the detecting device;
a cooled preamplifier disposed in said preamplifier housing; and
a thermally insulating connecting means disposed between and connecting said detecting device to said preamplifier housing,
the connecting means comprising at least one cooling line for supplying and returning a cooling fluid, and at least one RF
line for transmitting electric signals, said connecting means having a mechanically flexible connecting line, mechanically
flexible RF lines, and mechanically flexible cooling lines.
