The relative response to X-rays and light, linearity for X-rays, and the energy resolution for both X-rays and light signal from a light emitting diode (LED) light pulser were measured for 5 mm, 10 mm and 16 mm diameter large area avalanche photodiodes (LAAPDs). It has been shown that the ratio of the LAAPD gain for 5.9 keV and 16.6 keV X-rays and the gain for a light pulse from the LED light pulser was constant (within 1-2%) up to a device (optical) gain of 100. That allows using the X-ray peaks as a good reference for measuring the e-h pair number of detected light pulses, particularly from scintillators.
