The UltraLo-1800 is a revolutionary low background alpha-particle counter that employs Electronic Background Suppression to drive achievable background rates to 0.0001 alpha/cm2/hr or lower. This is a factor of 50 or more better than can be achieved by the conventional proportional counter systems that are now commercially available.

The PhosWatch detector is a plastic scintillator cell surrounded by a CsI crystal. The cell can be filled with samples containing small amounts of radioactive xenon or radon gas. Since these isotopes emit beta particles or conversion electrons simultaneously with gamma rays or X-rays, beta-gamma coincidence can be used to suppress the natural background and increase the detector's sensitivity. Due to the well geometry of the detector, beta particles are mainly absorbed in the plastic scintillator and photons are mainly absorbed in the CsI, which leads to characteristiv fast/slow pulses from beta-gamma coincidence events. Using pulse shape analysis algorithms implemented in the DGF Pixie-4, the PhosWatch can thus detect coincidences and simultaneously measure beta and photon energies with a single electronics readout channel.

The XIA Models DP-0X differential pumps provide a cost effective means of providing a windowless, direct, line-of-sight transition between an ultra-high vacuum (UHV) region (< 1 x 10-9 Torr) and a high vacuum (HV) region (< 1 x 10-4 Torr). Differential pumps traditionally consist of a series of pumps separated from each other and from the UHV region by flow restricting throttles. The DP-03 adheres to this arrangement, consisting of a pair of throttles separated by an active pumping region, but with the addition of a patented design feature that creates active pumping of line-of-sight molecules. An adapter nipple on one end facilitates connection to HV, while an adapter cross on the other end makes the connection to the UHV system as well as providing ports for pressure monitoring, viewing, and attaching the user supplied secondary pump which completes the system.
