This 45tesla magnet, which is a combination of superconducting magnet of 11.5tesla with a resistive one of 33.5tesla, is widely demanded among scientists all across the globe. This is actually the only magnet that has been featured in the Guinness Book of World Records.
IN HONOR OF NIKOLA TESLA
The unit was announced in 1960 during the General Conference on Weights and Measures.
Slovenian electrical engineer France Avčin gave the proposal for the name, and after accepting his idea this unit was named after the great physicist Nikola Tesla. So for more than 50 years we are proudly using Tesla Unit as a general unit of magnetic field strength.
ABOUT THE 45TESLA MAGNET
The superconducting magnet needs to be kept very cold, so most of the space in this two-story instrument is taken up by parts that are in charge of this. The magnet is kept at an incredibly low temperature of 1.8 Kelvin, a scientific measure equivalent to -271 degrees Celsius or -456 degrees Fahrenheit.
It’s connected to a closed system of machines and pipes that keep the magnet running by constantly making and recycling 2,800 liters of liquid helium. However the magnet needs to remain cold even when it’s not working. If it warms up to room temperature, it could take up to six week just to cool it back down to its operating temperature.
To keep the resistive part from overheating, the magnet also need cold water or around 15.000 liters of water are used every minute to keep it running.
This mighty instrument is only one of a few hybrids in the world. It’s not a surprise that this huge magnet costs the most to operate or about $1,452 an hour when at full field.
