Now while you might not like me when I'm angry, luckily none of you will have to fear me. I found out today that I am not being "belted by gamma rays", but instead by high power x-rays. The photo above is what I go through every weekday morning at 9:15. With a nice jazz background to keep me mellow. There is an adjustable metal shield in the source that creates the aperture to shape the beam, and the arm and table I'm on can both rotate to aim the beam from any direction. The aperture also has a thickness adjustment to provide the same power at the end target from every direction, even though from each direction the beam will be passing through different thicknesses of...well...skull and brain I guess. One of these days I'll keep my eyes open and see exactly what it does.
My hope now is that this was an off-day, and that tomorrow things will be back to "normal". Funny how meanings of words can change so quickly.
