Using ion chambers

The command for reading an ion chamber or chambers is

read_ion_chambers time detectorName1 [detectorName2 [...]]

All of the detectors must be associated with the same timer at the hardware level. After the command is issued, the wait_for_devices command can be issued to wait for the detectors to count over the requested time. After the wait_for_devices is issued, each of the readings for the ion chambers can be acquired individually using the get_ion_chamber_counts command in the following format:

get_ion_chamber_counts detectorName

Examples:

• Reading two ion chambers for 2.5 seconds

  	read_ion_chambers 2.5 i2 i5
  	wait_for_devices i2
  
  	#print the results to the log window
  
  	log_note [get_ion_chamber_counts i2]
  	log_note [get_ion_chamber_counts i5]
