CERN official 'elementary particle detector recipe' that can be made at home is on sale, DIY looks like this

The

European Organization for Nuclear Research (CERN) , the world's largest particle physics research facility that straddles Switzerland and France, has discovered the Higgs boson , which is the key to explaining the mechanism of mass generation, and HTTP, which is widely used on the Internet. He has made great achievements not only in physics but also in various fields such as the development of. Speaking of CERN, the elementary particle detector ' ATLAS detector ' installed about 100m underground is famous, but the method of DIY such an elementary particle detector is open to the public.

The elementary particle detector whose hardware design is open to the public by CERN researcher Oliver Keller is said to be an educational tool for exploring the radioactivity existing in the natural world. You can check the hardware configuration from the link below. Only parts that are easily procured are used.

There are two models of elementary particle detectors that are open to the public. The board design is common, and the range of

electron volts that can be detected by both models is 33 keV to 8 MeV. The difference between the two models is the type of photodiode that detects elementary particles, and the model that uses BPX 61 for the photodiode can detect alpha particles by removing the glass window of the photodiode.

The model that adopted BPW 34 F can detect only electrons, but it is said that the parts cost can be reduced accordingly.

Based on this parts list and hardware design,

Steve Foster, who lives in the UK, actually DIYs an elementary particle detector with his child and publishes the situation on his blog. Necessary parts Kitspace to the list of easy to procure because it is, but because some of the parts could not purchased separately, will cost a little extra, in addition to parts that have been listed, the substrate Ya He said he needed a tin can to store the battery. Even so, the total cost of making the detector was less than 40 pounds (about 5500 yen).

The tools used for DIY of the detector are tools necessary for board work such as soldering irons, cutting pliers, wire strippers, pliers, multimeters, nail punches for making holes in tin cans, and files. ..

The DIY process looks like this. First, solder the resistor to the board ...

Install the condenser.

With an

amplifier to amplify the detected signal ...

Solder the photodiode.

Attach the battery, switch, and

RF terminal to the board and put it in a tin can to complete the elementary particle detector.

It is possible to monitor the detection of elementary particles by inputting the signal from the RF terminal to the microphone terminal of the PC and displaying the waveform on the oscilloscope. However, recent sound cards remove the signal from the detector as noise, so the

Asus EeePC 901 released in 2008 received the signal.

According to Foster, the total production period of the DIY particle detector this time is about 6 weeks. As for the reason why it took so long, he said, 'For my 16-year-old son, the game was a higher priority than the project to make an elementary particle detector.'
