GR440 High Dose Rate Self-Contained Irradiator

Several high dose rate applications require the use of a self-contained research irradiator for calibration, production and other supporting research & development activities.  The Hopewell Designs, Inc. Model GR440 High Dose Rate Self-Contained Research Irradiator is a modern replacement for the legacy systems which are no longer supported.  The GR440 combines the well-known and understood capabilities and features of legacy systems with numerous state-of-the art design upgrades including larger chamber volume, a rotating chamber, higher precision timing/process control and greatly improved external (operator) dose rates.  Hopewell Designs, Inc. provides unparalleled service, preventative maintenance, technical support and source reloading for its entire product line.
