KLS Series Radiation-Resistant Linear Module | Used for Synchrotron Radiation Facilities

Core Perspective: "Ultra-long maintenance-free life" and "remote fault-tolerant control" in inaccessible, high-radiation environments
Once a beamline at a synchrotron radiation facility is commissioned, the internal equipment often must operate continuously for months or even years without the possibility of routine maintenance. Especially in the front-end regions subjected to radiation intensity of 10^6Gy, even robots cannot enter for service. Any motion module must possess "maintenance-free" characteristics by design. The KLS Series Radiation-Resistant Linear Module is precisely engineered for this purpose. This radiation-resistant linear module completely eliminates organic lubricants, instead employing solid lubrication (embedding) technology. Under high vacuum degree of 10^-7Pa and ultra-high dose rate irradiation, its coefficient of friction remains stable over the long term.
When the heat load from the synchrotron beam raises the ambient temperature to max +200°C, or when a liquid nitrogen-cooled monochromator requires cooling to min -196°C, the clearances of this radiation-resistant linear module are specifically designed to compensate for thermal expansion. This ensures it neither jams from interference fit at high temperatures nor develops excessive play causing instability at low temperatures. At the control level, this radiation-resistant linear module integrates radiation-hardened optical encoders and absolute position feedback. The ±0.01mm repeatability signal remains error-free even after cumulative radiation intensity of 10^6Gy
The massive body width of 170mm radiation-resistant linear module supports the first crystal of a double-crystal monochromator weighing up to the maximum horizontal load of 150kg. It adjusts the crystal's grazing angle at the nanometer scale to output X-rays of different energies. Conversely, the miniature body width of 30mm radiation-resistant linear module fine-tunes focusing mirrors for sub-millimeter beam spot adjustments. For pulsed neutron sources like the China Spallation Neutron Source (CSNS), the KLS Series Radiation-Resistant Linear Module must maintain position locking under strong vibration. Its unique brake design instantly locks the load upon power loss. For maintenance, this radiation-resistant linear module supports remote self-diagnostics and predictive maintenance by monitoring motor current fluctuations to estimate internal wear. More advanced is the modular design of the KLS Series Radiation-Resistant Linear Module, which allows the drive motor to be quickly replaced by a remote manipulator inside a hot cell without disassembling the main guideway body. In actual operation, this radiation-resistant linear module has demonstrated that after a cumulative dose of 10^6Gy, the degradation in its ±0.01mm repeatability is less than 5%. In conclusion, the KLS Series Radiation-Resistant Linear Module represents a design philosophy of "maintenance-free, radiation-tolerant, and high-reliability," making it an indispensable radiation-resistant linear module for extreme applications such as synchrotrons and nuclear waste handling.
