The maximum sensitivity of the electronic subsystem is limited by amplifier and other noise

present at the input. For discriminator settings in which there is less than 0.1 cps due to noise,

-14

the electronic subsystem maximum sensitivity is approximately 5.2×10 coulomb equivalent

charge at the input for the in-core sybsystem, and approximately 7×10 coulomb equivalent charge at the input for the out-of-core sybsystem with detector No. 6 (sensitivity ~ 0. 7 cps/nv).
