ENeXAr is a data archival tool for EPICS-based systems. It is intended as a complement for traditional data archiving solutions, to cover use cases for which they are usually not designed: mainly for limited-duration high-data rates from a subset of signals. The service is particularly useful for activities related to machine commissioning, beam studies, and system integration testing. Data acquisition is controlled via PV Access RPC commands and the data is stored in standard HDF5-based NeXus files. The RPC commands allow users to define the acquisition parameters, the data structure, and the metadata. The usage of EPICS RPC commands means that the users are not required to install additional software. Also, acquisitions can be automatized directly from EPICS IOCs.
