Advantages of electron synchrotron
① Has a smooth continuous spectrum in a wide range from infrared to hard X-rays. If a monochromator is used, monochromatic light of a certain wavelength can be obtained.
② The radiation intensity is high. The total radiation power of a storage ring is usually more than several kilowatts.
③ Good natural collimation, and its divergence is generally less than 1 milliradian.
④ High radiant brightness, generally 10 times higher than the X-ray target radiation mark, and 10 times higher than the continuous chirp radiation.
⑤ Has a natural polarization. On the orbital plane is completely polarized light, and its electric vector is parallel to the orbital plane.
⑥ High cleanliness. Because synchrotron radiation is free electron emission, no other particle background is produced.
⑦ Can be pulsed with a pulse width of 0.01 to 1 nanosecond or less.
⑧The luminous flux, energy distribution, and degree of polarization can be accurately calculated and are in good agreement with experimental values, so it can be used as a standard light source.
