  For operating a 100MeV linear proton accelerator, the major driving values
and experimental data need to be archived. According to the experimental
conditions, different data are required. It is necessary to implement functions
that can add new data and delete data in real time. In an experimental physics
and industrial control system (EPICS) input output controller (IOC), the
process variable (PV) values are matched with the driving values and data. The
PV values are archived in text file format using the Channel Archiver. There is
no need to create a database (DB) server, just need a large hard disk. Through
the web, the archived data can be loaded and new PV values can be archived
without stopping the archive engine. Implementation of a Data Archiving System
with Channel Archiver is presented and some preliminary results are reported.
