Low Cost DIY Scientific Equipment


It is not true that to make high-level educational scientific experiments it is necessary to spend a lot of money to buy the necessary equipment. Often with a bit of good will, time and lot of patience you can build everything you need : you save, you learn and you have fun !

Webcam Nuclear Particle Detector





Source = Strontium (90Sr) 0,1μCi
CPS (counts per seconds) = 1,38
Trace Length = 33px * 6μm = 198 μm
The CMOS sensor detects the beta radiation emitted by the decay of strontium. In the picture aside you see the magnified image of the track of an electron.

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.
