Abstract
Apparatus for the controllable downhole production of ionizing radiation (), the apparatus including at least a thermionic emitter () which is arranged in a first end portion (a) of an electrically insulated vacuum container (), and a lepton target () which is arranged in a second end portion () of the electrically insulated vacuum container (); the thermionic emitter () being connected to a series of serially connected negative electrical-potential-increasing elements (), each of said electrical-potential-increasing elements () being arranged to increase an applied direct-current potential (δV, δV, δV, . . . , δV) by transforming an applied, driving voltage (V), and to transmit the increased, negative direct-current potential (δV, δV, . . . , δV) and also the driving voltage (V) to the next unit in the series of serially connected elements (), and the ionizing radiation () exceeding 200 keV with a predominant portion of the spectral distribution within the Compton range.
