1. A multitube X-ray emitter housing, comprising:
a housing with at least one side surface;
a high-voltage supply;
a cooling device with an electrically insulating cooling medium, wherein
inside the housing, the high-voltage supply has a single high-voltage supply lead to conduct a high voltage, and a plurality of high-voltage contacts connected in parallel on the single high-voltage supply lead,
the plurality of high-voltage contacts, in each case, are configured to be coupled to a high-voltage electrode to provide the high voltage and are at a same high-voltage potential,
a first of the at least one side surface has a first electrically conductive housing portion with a temperature-dependent electrical conductivity, and
the electrically insulating cooling medium is located between the first electrically conductive housing portion and one of the plurality of high-voltage contacts;
a control unit having an interface configured to receive a measured value representing an electrical conductivity of the first electrically conductive housing portion, and to compare the measured value with a threshold value; and
a switching device configured to switch off the high voltage based on the comparison.
