Abstract: A plasma panel based ionizing-photon radiation detector includes an input and output substrate with gamma-ray to free-electron conversion occurring primarily on the input plate and a sealed discharge gas between the substrates. X-electrodes and Y-electrodes are formed on the two substrates and configured to form a plurality of pixels. Impedances are coupled to the X and Y electrodes and a power supply is coupled to the X-electrodes. Discharge event detectors coupled to impedances detect discharge events on the Y electrodes and at the pixel locations, which leads to the detection of ionizing-photon radiation.

Abstract: An array gas electron multiplier (GEM) digital imaging radiation detector and a control method thereof are disclosed. The array gas electron multiplier (GEM) digital imaging radiation detector includes an array GEM detector. The array GEM detector includes: an ionized electron generation unit for generating ionized electrons in internal filling gas by incident X-rays or gamma rays or by incident charged particles; a gas electron multiplication unit for multiplying the ionized electrons of the ionized electron generation unit in filling gas inside hole of a gas electron multiplier (GEM), through electron avalanche effect, using the GEM, to form electron clouds; a readout for detecting and outputting coordinates of the electron clouds as the readout receives positions through electrical signals, in which the positions of the electron clouds, being multiplied and formed in the gas electron multiplication unit, reach output electrodes. Therefore, the present invention can multiply ionized electrons of internal filling gas as a gas electron multiplier (GEM) generates an electron avalanche effect in the hole thereof, in which the ionized electrons are generated as a photo-electron effect or a Compton effect is induced by high energy incident light, such as X-rays or gamma rays, or which are directly generated by incident charged particles, and can convert image information of the inside or outside of an target object into images of two-dimensions, in real time, such that the detector can be properly used as a security search apparatus in a harbor or an airport, or can be adapted as a core part of industrial nondestructive testing apparatus.

Abstract: Methods, apparatus and systems for detecting charged particles and obtaining tomography of a volume by measuring charged particles including measuring the momentum of a charged particle passing through a charged particle detector. Sets of position sensitive detectors measure scattering of the charged particle. The position sensitive detectors having sufficient mass to cause the charged particle passing through the position sensitive detectors to scatter in the position sensitive detectors. A controller can be adapted and arranged to receive scattering measurements of the charged particle from the charged particle detector, determine at least one trajectory of the charged particle from the measured scattering; and determine at least one momentum measurement of the charged particle from the at least one trajectory. The charged particle can be a cosmic ray-produced charged particle, such as a cosmic ray-produced muon. The position sensitive detectors can be drift cells, such as gas-filled drift tubes.

Abstract: A high voltage diamond based switching device capable of sustaining high currents in the on state with a relatively low impedance and a relatively low optical switching flux, and capable of being switched off in the presence of the high voltage being switched. The device includes a diamond body having a Schottky barrier contact, held in reverse bias by the applied voltage to be switched, to an essentially intrinsic diamond layer or portion in the diamond body, a second metal contact, and an optical source or other illuminating or irradiating device such that when the depletion region formed by the Schottky contact to the intrinsic diamond layer is exposed to its radiation charge carriers are generated. Cain in the total number of charge carriers then occurs as a result of these charge carriers accelerating under the field within the intrinsic diamond layer and generating further carriers by assisted avalanche breakdown.

Abstract: An energy filter with reduced aberration. The energy filter has a first stage of filter for receiving an electron beam entering along the optical axis and for focusing the beam in one direction vertical to the optical axis and a second stage of filter positioned along the optical axis behind the first stage of filter. The beam once focused by the first stage of filter is made to enter the second stage of filter. In the second stage of filter, the orbit of the electron beam is inverted with respect to the focal point. The two stages of filters are identical in length taken along the optical axis. The first and second stages of filters have electric and magnetic quadrupole fields, respectively, along the optical axis. These quadrupole fields make an angle of 45 degrees to the optical axis to achieve astigmatic focusing.
