ADDITIONAL PRODUCT INFORMATION
The Cx-L Spectroscopic Amplifier has a Gaussian output signal with 180 ns FWHM. The low baseline noise of 300 electrons allows high-resolution particle spectroscopy, in particular for high particle rates up to 1 MHz.
The width of the Gaussian output signal can be customized for the readout with a conventional multi channel analyzer to 1.2 μs FWHM.

The Cx-L Spectroscopic Amplifier is optimized for particle spectroscopy with high capacitive input load. The signal-to-noise ration (SNR) for 1 MeV energy deposition in diamond detectors, as function of the input capacitance is shown in the Figure.
At 1 nF input capacitance an SNR of 10 is achieved for 1 MeV equivalent energy deposition in diamond. This shows that the Cx-L Spectroscopic Amplifier can be operated with 10 m long 50 Ω cables at the input.
