It has long been believed that the semiconductor photocathode e-beam technology is suitable for academic purposes only and inappropriate for industry usage. This is because no one has ever proved its long term performance. However, the results here show it can be used in production environments with confidence.

We will keep testing continuously and further prove the superiority of this technology.
