Charge Sensitive Preamplifier (CSP)
The charge sensitive preamplifier (CSP) is a circuit in which the current pulse generated by a detector is converted into a voltage pulse by means of the charge of a capacitor. In the image below it is presented our “low cost” CSP.
The charts below show the signal from the detector (blue) and the signal produced by the CSP (yellow).

Trans – Impedence Amplifier (TIA)
The trans – impedence amplifier (TIA) is a circuit in which the current pulse generated by a detector is converted and amplified into a voltage pulse by means of the voltage generated in a resistor. In the image aside there is our TIA used for the SiPM detectors.
The chart below show the signal from the detector (blue) and the signal amplified by the TI (yellow).

X-Ray Generator
A simple, DIY and low-cost X-Ray generator could be very useful ! The images below show the apparatus we have built with a russian NOS X-Ray tube. We built also a cabinet with a HV section and with the ammeter to measure the anodic current. The filament is fed with a constant-current power supply. Important ! The tube must be covered with a lead shield in order to prevent x-ray from going out in directions others than the front direction.

Pulse Counter
With a PSoC microcontroller we have built a simple threshold pulse counter. This equipment is very useful in several applications such as photon counting or radiation counting. A feature of this counter is the threshold which can be modified with a trimming potentiometer, between 0 mV to 1000 mV. The measaurement is done in CPS (pulses per seconds) or in CPM (pulses per minutes) and it is also calculated the statistical error.
Charge Sensitive Preamplifier – Shaping Amplifier from Micod
Micod is a russian company which build some excellent front-end electronics for scintillators-photodiode.
High Voltage Generator
With a second-hand Matsusada HV module it is easy to achieve a low noise, adjustable, high voltage generator to drive PMT, SiPM, CZT and other detectors.

With this Micod HV module it is easy to achieve a low noise, adjustable, high voltage generator to drive PMT, SiPM, CZT and other detectors.
Photon Counter
With a PSoC microcontroller we have built a simple “Photon Counter” to be coupled to a PMT. This equipment is very useful in several applications. The features of the Photon Counter are the following :
- Simple Counter : it counts the pulses and calculates the rate (in CPS) and the square deviation.
- Time Gated Counter : it counts the pulses received within a time frame determined by the Gate pulse, the count is enabled when the Gate input is at a high level.
- Fast Timer : it measures the time interval between a Trigger pulse and the first received pulse.
- Pulse Interval : measures the time interval between one pulse and the next.
Photometer
With a PSoC microcontroller we have built a simple “general purpose” photometer, based on a photodiode sensor and on a Cypress PSoC5LP microcontroller. The photometer is the instrument that measures the intensity of a light emission, its applications range in many different sectors, including chemical and biochemical analyzes and the study of light sources. To make the instrument “flexible” we have chosen to keep the sensor separate from the body of the instrument : in this way it is adaptable to different modes of operation.
Fast Pulser
10ns fast light pulser, it is based on a LED driven with the ZTX415 avalanche transistor.
Ultra High Voltage
Ultra high voltage generators, based on flybak trafo or CCFL inverter followed bay voltage multipliers. We have two size: 0- 60KV and 0-15KV.
Teslameter
0-3T Hall-effect magnetometer. With Arduino mini and the CYSJ362A hall-sensor.
