It seems to that the body of the laser had bent back to its original geometry from the time we've got the laser in 2018. It has probably happened due to the different location and maybe better floor. The intermittent issue of the tube switching off could not be replicated, the HV wires were checked but no obvious burn or oxidation marks have been identified. | ||
