Abstract

We have built a fluorescence imaging system with a nonmagnetic front end photodiode array (PDA) located inside a magnetically shielded science region. The PDA is connected by a bundle of 2 m long mini-coaxial cables to a set of external bootstrapped amplifiers with 10⁷ Ω trans-impedance and a peak light-equivalent spectral noise density of 2.0 pW/√Hz in a 150 kHz bandwidth. The detector is being used for a cold atom electron electric dipole moment search experiment.
