Geo,

My Kevex’s are PXS4-613W and ?run with a CU015 60 kV power supply.

Target Voltage:? 5.0 to 60.0 kV

Current:? 0.01 to 1.00 mA

X-ray source spot size: 0.01” x 0.020” (0.25mm x 0.45 mm) Approximately

X-ray Output: 101R/min at 60 watts

X-ray Window: 0.005” (0.13mm) Be

Angle of illumination: 35 degrees inclusive (Approx)

When you first fire it up or when it’s been sitting for a long while ramp up the voltage in 20% steps at 10 % of max current steps ?to allow the tube to outgas. Do this over a 10- to 15 min period (1 minute minimum at each step) before going to full power. Watch out for arcing. ?Don’t run prolonged operation at 5kV or less at high beam current as that will run the filament hotter than normal and will decrease the filament life.

They warn that the X-rays are dangerous and ?may be fatal. The X-ray tube window must be placed in a shielded chamber. It’s also clearly stated not to let anyone named Geo operate this machinery.
