Particle Accelerator & Energy Consumption

[Bjarne]

How much energy is a accelerator using when keeping particles orbits (by constant speed):

for example:

2.99999997 E8 m/s (or topspeed)
2.98000000 E8 m/s
2.97000000 E8 m/s
2.80000000 E8 m/s

Please mention the energy consumption in % relative to the top-speed (I believe it is - 2.99999997 m/s) or in MW relative to the numbers of particles in orbit.

For stored protons and anti-protons (~1 x 10¹³ of each) at Fermilab, they radiate a few milliwatts even at 980 GeV in the 6.28 kilometer circumference orbit. The superconducting magnets have resistive losses only in the connections between them (a few nano ohms per connection at 4000 amps). Keeping the magnets at 4 kelvin took lots of liquid helium cooling. Producing anti-protons took a lot more. For electrons, running LEP (the former large electron proton collider at CERN) with a 26 kilometer circumference, at full energy the accelerator used roughly the same amount of power as the entire city of Geneva (I think).

I can provide some insight into the energy consumption of a particle accelerator when keeping particles in constant orbit at various speeds. The amount of energy consumed by a particle accelerator is directly related to the speed at which the particles are orbiting. The faster the particles are moving, the more energy is required to maintain their orbit.

In the example given, the top speed of 2.99999997 E8 m/s would require the highest amount of energy consumption. If we use this speed as a reference point, the energy consumption for the other speeds can be calculated as a percentage relative to the top speed.

For the speed of 2.98000000 E8 m/s, the energy consumption would be approximately 99.33% of the top speed's energy consumption. Similarly, for the speeds of 2.97000000 E8 m/s and 2.80000000 E8 m/s, the energy consumption would be approximately 99% and 93.33% of the top speed's energy consumption, respectively.

It is important to note that the actual energy consumption may vary depending on the specific design and efficiency of the particle accelerator. Additionally, the number of particles in orbit can also affect the energy consumption, as more particles would require more energy to maintain their orbits.

In terms of energy consumption in MW (megawatts), it would depend on the specific design and number of particles in orbit. However, we can estimate the energy consumption in MW relative to the number of particles in orbit. Assuming a constant energy consumption per particle, the energy consumption would increase linearly with the number of particles in orbit.

In conclusion, the energy consumption of a particle accelerator is directly related to the speed and number of particles in orbit. The higher the speed and number of particles, the higher the energy consumption. The actual energy consumption can vary depending on the specific design and efficiency of the particle accelerator.
