How To Build A Simple Particle Accelerator

[ThomasSatt]

Hello, all. I've heard of a few renowned scientists having build small particle accelerators in their garages as teenagers, and I've wondered how I could do the same. Obviously, I'm not looking for anything LHC-scale, but rather a few feet in circumference. I've seen similar projects on the internet, but never stating how to build it, or where to start. So how would I go about creating a small, low voltage particle accelerator? How would I create the vacuum? How would I capture the starting hadrons? How would I accelerate them? How would I observe them? How would I collide them with something else? I realize that this is a very complicated topic, but I am very interesting in pursuing it. Thank you very much in advance.

You start by learning classical electrodynamics, special relativity, and some basic particle physics. Once you understand these subjects, most of the questions you have will clear themselves. Until then, giving you any practical advice would only help you injure yourself.

ThomasSatt, Welcome to Physics Forums!

Using the Google search terms “how to make a small particle accelerator” I found these two threads from here on Physics Forums. Also, there are lots more additional sites you can visit.

Bobbywhy neglected to mention that both of those threads were locked because this is difficult and dangerous, especially if one does not have the proper background.

Hello,

Building a particle accelerator, even a small one, is a complex and challenging task. It requires a deep understanding of physics, engineering, and advanced technology. I would highly recommend seeking guidance and supervision from experienced professionals in this field.

That being said, here are some general steps to consider when building a simple particle accelerator:

1. Research and Planning: Before starting any construction, it is essential to conduct thorough research and planning. This includes understanding the principles of particle accelerators, the required components, and safety measures.

2. Design and Construction: Once you have a solid understanding of the basics, you can start designing your accelerator. This includes selecting the type of accelerator (e.g., linear or circular), choosing the appropriate materials, and constructing the necessary components.

3. Power Supply: A particle accelerator requires a high amount of energy to operate. You will need to source a reliable power supply and ensure proper safety measures are in place.

4. Vacuum Chamber: A vacuum chamber is essential for creating a low-pressure environment necessary for particle acceleration. It is typically made of stainless steel and requires precise sealing to maintain the vacuum.

5. Particle Source: To create particles, you will need a particle source, such as a radioactive material or a gas ion source. The particles are then injected into the accelerator.

6. Acceleration: The particles are then accelerated using an electric field. The strength of the field and the length of the accelerator determine the particles' final energy.

7. Observation and Detection: To observe and detect the particles, you will need specialized equipment such as a detector or a scintillation screen. These devices can measure the particles' energy, trajectory, and interactions.

8. Collision: If you want to collide particles with other particles or targets, you will need to design and install a collision chamber and a target.

Again, I strongly recommend seeking professional guidance and supervision before attempting to build a particle accelerator. It is a complex and potentially dangerous project that requires extensive knowledge and expertise. I wish you all the best in your pursuit of this fascinating field of study.

Best regards,
