Investigation of the nature of the secon peak in the second hit mode.

1. LED is in non-updating mode, 30 mV threshold, 40 ns pulse width:

2. LED is in updating mode (in hope to get rid of the second pulse), 30 mV threshold, 40 ns pulse width:

Second pulse is still there.

Another case of the second pulse appearance (same conditions):

Run #	Description
8839	500 ps pulse width, 800 mA peak current, 200 Hz rep. rate, no target, 50 mV LED (all), 40 ns LED (all), 1cm Al radiator, N(gamma, TDC24) = 1/6.7
