Cremat's charge sensitive preamplifiers (CSPs) can be used to read out pulse signals from radiation detectors as diverse as semiconductor radiation detectors (e.g. CdTe, CZT), scintillator-photodiode detectors, gas-based detectors such as ionization chambers and proportional counters, and photomultiplier tubes (PMTs).

Cremat offers four different charge sensitive preamplifier models:
CR-110, CR-111, CR-112, & the CR-113. These preamplifiers are all modules of the same size and are pin-for-pin compatible with each other. They differ from each other primarily by their gain, with the
CR-110 having the highest gain (1.4 volts per picoCoulomb). The
CR-111 gain is a factor of 10 reduced (0.15 volts per picoCoulomb). The gains of the CR-112 (15 mV per picoCoulomb) and CR-113 (1.5 mV per picoCoulomb) are reduced in gain by additional factors of 10, making them suitable for use with detectors producing large signals such as PMTs, etc..

For information on choosing the best preamplifier for your application, see our Tips on choosing a preamplifier page. Users seeking more information on the how to best implement these preamplifiers should see our CSP Application Notes. We also offer an illustrated example of a detection system constructed using Cremat modules. Specifications for our charge sensitive preamplifiers can be accessed from the following links:

Use with CR-150

Cremat's charge sensitive preamplifiers can easily be tested using the CR-150 series of evaluation boards.
