Charge sensitive preamplifiers explained

Use a charge sensitive preamplifier (CSP) design to detect pulses with high precision and low noise. Learn more here.

What to buy to read out your detector

Want to know exactly which parts you need to buy for your type of detector? Find detailed descriptions for these types of detectors:
PIN photodiodes
Avalanche photodiodes
SiPM photodiodes
Gas-based detectors
Surface barrier / PIPs detectors
PMTs / Faraday cups / Channel electron multipliers

Which CSP module should I use?

Here is a selection guide of our four CSP modules.

Detect femtoJoule optical pulses

With a common pin photodiode, a low noise charge sensitive preamplifier and shaping amplifier, you can detect femtoJoule optical pulses. Here is a demonstration.

Input protection notes

Extremely large input pulses caused by sparking detectors can destroy CSPs. Read here on methods to protect the input, if necessary.

How to couple your detector

You can use different methods to couple your detector to the preamplifier. Learn more here.

Testing a CSP

Need to verify that everything is working as intended? Inject pulses from a wave generator to the ‘test input’. Details here.

What polarity is the output?

Here is an explanation of the preamplifier output polarity in various situations.

Applying power to Cremat’s evaluation boards

To power Cremat eval boards, you can apply both + and – DC power or you can use a wall mounted power supply such as the CR-24V. Here is what you need to know.

Tips for getting good results

Here is advice to help you design and develop your own detection instrumentation using Cremat CSP modules.

Won’t the long decay tail cause problems with pulse pile-up?

The output pulse of a CSP takes the form of a short rise time (<1μs) followed by a long exponential decay lasting well in excess of 100μs. Won’t this be a problem when detecting pulses at a high rate as the pulses will ‘pile-up’ on each other? See an explanation here.

Modular approach

Use a modular approach in developing radiation detection instrumentation. Changes or repairs may be simply effected by changing modules.
