Latest Patents

One of Poelker's key inventions is the Wien filter with integrated vacuum pump. This patent describes an integral Wien filter and vacuum pump designed for separating charged particles or orienting their spin direction while maintaining optimal beamline vacuum. The vacuum pump is an ion pump that includes one or more cylindrical Penning cells to trap and expel electrons. The Wien filter utilizes orthogonal electric and magnetic fields to direct particles with the desired speed through the device while deflecting those at undesired speeds. The design features two electrodes, one biased positive and the other negative, along with a dipole magnet. Additionally, it includes means for reversing the polarity of the electrodes to flip the spin of the charged particles. The metal plates on either side of the Penning cells embed gas that is ionized by trapped electrons, thus creating vacuum by turning gas into solid. The configuration of the two metal plates allows for vacuum pumping via chemical gettering and the removal of noble gases. Poelker holds 1 patent for this innovative technology.
