Laser Safety Reminder
- To be present in a secured laser area at ATF, a person must either
have the required laser training, or be continuously escorted by someone
who has such training:
The training consists of an eye exam, BNL general laser safety lecture,
and formal ATF laser familiarization. Untrained personnel should not
be instructed to enter interlocked areas or be escorted into an area
and left unattended. If someone without training must enter a secured
area, they must be continuously escorted, and are considered spectators,
which means they may not perform any work in the area.
- At ATF, there are 3 classes of personnel authorized to enter
1. Experimental operators may secure areas, perform approved experiments
with beams from facility lasers (YAG + CO2) or FEL beams, and shut down
the YAG system
2. ATF operators may additionally turn on the YAG system for linac
3. Laser operators may perform any tasks with ATF lasers
- When entering a secured area, appropriate eye protection must
Each entry into a secure area has indications as to which wavelengths
are or may be present, so that the appropriate eye protection may be
selected. Beam hazards in the area are regulated by controlled keys,
and it the responsibility of both the keyholder and any other personnel
in the room to maintain awareness of the hazards present.
- Interlocks are safety systems and may not be defeated under any
Any malfunctions must be reported to the CAD interlock group. The interlock
system has a failsafe design, and if problems arise which impede operation,
only the CAD interlock group may modify the interlock system.
- Work which requires laser interlock in common areas (i.e. experimental
hall, FEL room) should be scheduled ahead of time to avoid conflicts.
When an area is secured, an announcement over the PA system should be
used to notify ATF personnel.
