In the accelerator field, the instrumentation includes the vacuum, magnet, RF, utility, cryogenic, power, safety, optic device and so on. The highly complicate systems have many hybrid SCADA systems to ensure precise and optimum control. For the historical data integration and analysis of those signals, the monitor and archive system is introduced to provide a distributed multi-channel acquisition platform. The system possesses various connectivity of open database, communication protocols and commercial hardware. The signal data can be collected and delivered to the central Storage Area Network (SAN) via fiber network without latency. Finally, the unique, friendly and fast trend logger and data analysis software are also developed to view, compare, and analyze relation between facility at any time and anywhere.

This paper presents the air temperature analysis and control improvement for the injection area at the Taiwan Light Source (TLS). The injector consists of a 50-MeV LINAC and a 1.5-GeV booster synchrotron. Because of insufficient cooling capacity, the air temperature was too high ( > 27 degree C ) and the temporal temperature variation was more than 2 degree C in one day. The air relative humidity was often higher than 60%. The problem of insufficient cooling capacity became more serious after the top-up mode operation. To cope with the abovementioned thermal problem, the cooling capacity was increased and the PID parameter of the temperature control was also optimized. Totally 18 temperature sensors were distributed in this area to on-line record the air temperature history. The temperature control was improved to suppress temporal temperature variation within ± 0.1 degree C. The thermal uniformity was also much improved than ever.
