X-ray Tube Power Supply
Shasta series

Oxford Instruments Shasta series power supply features a robust design that has been
optimized to power grounded filament X-ray tubes from Oxford Instruments, yet its
versatility enables it to power virtually any grounded filament X-ray tube.
Utilizing closed loop emission control circuitry that delivers low ripple, Shasta
provides highly regulated beam current and high stability resulting in superior
performance. Local and remote analog control enables convenient operation
in setting voltage & emission current.
Models with grid focus control are designed to provide optimal
performance with our Apogee tubes
