Yag screen (100 um thick) monitored by a diode at a fix distance
The Yag screen is imprinted with tick marks for conversion pixel to mm (the tick marks are separated by xxx and are xxx thick)
# (yag number)
yag# 'enter' - displays the current yag status
motors:
yag#.dy - brings the yag/diode up and down
yag#.zoom
also for the zoom:
there is a screen in xpphome where the zoom of the yags are specified in a 1 to 12 scale, and also two user/non-permanent navitars where you specify the pv value.
in python it can also be controlled by:
yag#.zoomlvl(1to12)
yag#.zoomlvl_calibrate() for calibrating the zoom
pseudomotors:
yag#.screenin()
yag#.all_out()
yag#.lighton()
yag#.lightoff()
detector channels:
d.dio#.ch0
