Description
VERITAS (HB-1A) located in the thermal beam room at HFIR, recently completed a major upgrade to rebuild the entire instrument. The instrument utilizes a double-bounce pyrolytic graphite monochromator system and a pyrolytic graphite analyzer to produce an intense, clean beam at l = 2.38 Å with low background and an excellent signal-to-noise ratio. The upgrade resulted in a >4x signal gain and enables two new capabilities on VERITAS: a new four-circle goniometer capability which has been successfully commissioned and is now available in the user program; and a small 2D detector option at the analyzer position which is under development and will become available soon. With its large Q-coverage (0.1 to 4.8 Å-1) and open sample position, VERITAS is optimized for magnetic diffraction studies supporting a wide range of complex sample environments.
