Description
In order to protect the vacuum system for the Taiwan Light Source (TLS), a vacuum
interlock system has been developed. The status of all the vacuum devices,
including the sector gate valves, ionization gauges, and the pumps, are monitored
and hence the vacuum system can be protected as soon as a vacuum failure happened.
In addition, an alarm system has been established to monitor the temperature of
vacuum chamber as well as the temperature and flow rate of cooling water system, to
avoid the vacuum chambers from melt-down. Recently, the interlock system has been
upgraded by including the interlock systems of all the front ends and the
temperature alarm system to assure the vacuum quality of the storage ring. This
interlock system has been functioned well since the first operation. The
architecture of logic design and the features of the interlock system will be
described. Besides, a program has been established for archiving the readings of
all the vacuum devices and the temperature monitoring systems that can be accessed
through the internet for real time comparison of the relationship of various
signals. Some experiences of unexpected failures or the malfunctions of the vacuum
devices will also be illustrated.
