Kunshan Proton Laser Equipment Co., Ltd. (referred to as "Proton") was established in 2007 as the Proton Laser Research Center and officially became Kunshan Proton Laser Equipment Co., Ltd. in 2019. It is recognized as a national high-tech enterprise.

To date, "proton" is considered a stable and non-decaying particle. However, there are theories suggesting that protons may eventually decay, albeit with an extremely long lifespan. As of now, physicists have not obtained any experimental data that could be interpreted as evidence of proton decay.
