A low minimum threshold permits proper back termination of phototubes or allows use of small, lower-gain photomultipliers without the necessity for a separate amplifier. Recessed behind the front panel, they cannot be changed inadvertently during the course of an experiment. Output width is independent of input duration, amplitude, and rate. No need for width cables, etc. Low time slewing permits accurate timing even in experiments experiencing wide distributions of input amplitudes.
Deadtimeless operation updates the output pulse to reflect the most recent input signal.
Compact packaging and low power consumption permit up to 24 discriminator channels to be powered from one 72 watt NIM Bin. The threshold of each channel is checked for variation with input width, input risetime, rate, temperature, and supply voltage change to assure optimum performance and long, reliable service life. Moderately priced to appeal to today's larger experiments and smaller budgets. 15 ns to 8.5 usec, may be obtained as an option. Completely compatible physically and electrically with LRS Power Chassis Model 108P, and with any other AEC power bin of any manufacturer.
