CR-200

Description

The CR-200 is a single channel shaping amplifier, intended to be used to read out the signals from charge sensitive preamplifiers (e.g. Cremat CR-110 or equivalent). Gaussian shaping amplifiers (also known as pulse amplifiers, linear amplifiers, or spectroscopy amplifiers) accept a step-like input pulse and produce an output pulse shaped like a Gaussian function. The purposes of CR-200 are to filter much of the noise from the signal of interest and to provide a quickly restored baseline to allow high counting rates. The CR-200 is available in 4 different shaping times: 100 ns, 250 ns, 1 s, and 4 s. Each has a fixed gain of 10. If additional gain is desired, it is recommended that this be done with the application of an additional amplifier between the preamplifier and the CR-200 shaping amplifier. Cremat offers an evaluation board (CR-160) which includes a variable gain amplifier of appropriate bandwidth, as well as all necessary connectors.
