A particle beam detector array with a cathode plane offset from an anode plane and a sensitive region between the cathode plane and the anode plane. The cathode plane and the anode plane are configured to create an electric field within the sensitive region. The anode plane has sensor pads configured to conduct electric current based on the fluence and position of an incident particle beam. A first plurality of conductive pins extends away from the sensor pads into the sensitive region. Each pin of the first plurality of pins is electrically coupled to one of the sensor pads. The sensor pads may be coupled to a series of strips with at least two layers, where each layer is associated with a different axis of at least two axes. A second plurality of pins may be electrically coupled to and extend away from the cathode plane into the sensitive region.

In some embodiments, a cathode assembly may include a cathode head that has a first electron emitter and a second electron emitter. The first electron emitter may have a first connection location and a second connection location. The second electron emitter may have a third connection location and a fourth connection location. The third connection location may be electrically coupled with the second connection location of the first electron emitter. The cathode assembly may include a receptacle having a first connector and a second connector. The first connector may be electrically coupled with the first connection location of the first electron emitter. The second connector may be electrically coupled with the second connection location of the first electron emitter and the third connection location of the second electron emitter. The third connector may be electrically coupled with the fourth connection location of the second electron emitter.

A radiation beam window assembly may include a substrate and a spacer panel comprising a rigid low-density core with first and second fiber skins disposed on opposing surfaces of the foam core and a central opening disposed completely through the spacer panel and disposed over the substrate. A beam window panel may comprise a rigid low-density foam core comprising first and second fiber skins disposed on opposing surfaces of the foam core. The beam window panel may further include a cathode formed over the first fiber skin and aligned with the central opening of the spacer panel. A channel may be formed completely around a perimeter of the cathode, and the second fiber skin may comprise a ground ring. A pressure plate may be disposed over the beam window panel and mechanically coupled to the substrate, the pressure plate comprising a conductive layer configured to be electrically grounded with the ground ring.

A particle beam detector system can comprise a particle beam generator, a particle beam fluence and position detector array based on Micromegas technology, and data readout electronics coupled to the position detector array. The particle beam fluence and position detector array can comprise a sealed, gas-filled, ionizing radiation detector chamber. A printed circuit board (PCB) can be disposed within the ionizing radiation detector chamber, the PCB comprising a multi-layer array arrangement of interconnected conductive sensor pads comprising three planar coordinate grids, X, Y, and ST (stereo) situated on separate layers of the PCB. The multi-layer array arrangement of interconnected conductive sensor pads can comprise a first footprint. A dielectric lattice structure can be disposed over the PCB and the multi-layer array arrangement of sensors. A conductive mesh structure can comprise a second footprint disposed over the dielectric lattice structure and extending over an entire area of the first footprint.
