The presented systems are aimed on increasing the accelerator radiation safety.
They are built as independent hardware distributed systems. The Beam Abort
Triggering System reacts immediately when accidents occur creating triggers for
kicker magnets to dump the beam. The Beam Dynamic Interlock System prevents the
beam transfer to the next stage of the accelerator complex if it is not ready
for this operation (i.e., magnetic field is out of range, bad vacuum, etc.).
Conventional computer control means are only used for post-mortem diagnosis and
selftesting during beam pauses. The paper describes the conception and
components of the systems. The focus is made on the UNK Abort System Triggering
under development and U-70 to UNK Transfer Line Dynamic Interlock System which
has been created and used during the launching of the Beam Transfer Line in
1994.
