Introduction to screens (ref):

• standard
  • slow
  • calcium tungstate
• rare earth
  • fast
  • gadolinium or lanthanum
  • Commercial brands: Kodak Lanex

There's a good vendor summary / cross reference chart here: http://www.mcio.com/Products/comparison-chart.aspx

I think the number following the name is generally the gain. That is a 400 screen will put out twice as much light per x-ray as a 200 screen They call this the “speed” presumably because it makes film expose faster. Chart here

was offered a broken tube but I don't think it would have been useful

Ben K x-ray, CBCT “chicken” setup

• originally unshielded but I think is now?
• In CBCT mode runs automatically via arduino and thus person doesn't have to get exposed

• …who gave himself acute radiation sickness. A stern warning to those not taking such a setup seriously

John M dental x-ray setup

• which has about 100 lbs of lead shielding
• also operated remotely via ssh to laptop

Goal: stop using my Sherline rotary stage and instead use spare CNC rotary stage (from laser machine purchase lot)

Motor: Vexta PH566-B 5 phase stepper

Controller: Rorze RD-053MS

• Datasheet] * [[http://www.rorze.com/english/Tech/controll/RD053MS.pdf|Spec sheet
• Has a lot of pins labeled
• Enclosed in box with cable running to the rotary table
• 3 per box
• Need to interface to output Centronix connector

The left side connections are pretty obvious:

• power
• motor phases

Left side less so

• diff1
• diff2
• 4P IN
• FREE
• PHASE OUT
• ALARM OUT
