| Abstract: | The moveable helium liquefier in the Key Laboratory of Superconducting Cavity Technology of SINAP has stopped operation for years. As the original control system has become obsolete, it is necessary to make some repairs and improvements. The upgraded control system employs a distributed control strategy and a mature PLC technology. The test results show that the new control system can meet the operation requirements of the liquefier well. |
