LCLS Transition to Science
DOE Status Review of the LUSI MIE Project
An IRR is…
Part of a layered approach for assuring safe, reliable,
and efficient operation of LCLS
Consistent with SLAC Guidelines for Operations
Chap. 23, Accelerator Safety Reviews and Unreviewed Safety
Issues
Described in XFD document 030-00200-000
Motivated by plans to add 6 major instruments for x-ray
experiments at LCLS over 3-year period
A way to assure that all USI associated with new LCLS
instruments have been identified and mitigated before
starting commissioning of the instrument
A tool that will also be used for reviewing major changes
to instruments after they are operational

An IRR is not…
A replacement for normal SLAC WPC
A replacement for the SLAC USI process
Appropriate for minor repairs or changes to LCLS
instruments
Appropriate for review of each LCLS experiment

How IRR process is used
Coordinated by Instrument Scientist
Takes place when instrument is nearly complete, but
allows time to address pre-start issues
May require modification of SAD and/or ASE
Modified SAD must be approved by SLAC Director
Modified ASE must be approved by DOE SSO
After all IRR pre-start issues are closed, LCLS Director
authorizes start of commissioning

Who is involved in IRR
Instrument Scientist coordinates
Radiation Physics group reviews shielding, beam
containment issues
SLAC safety committees review issues in their areas
IRR committee has formal meeting to assess status of
reviews, identify pre-start and post-start issues
Committee composed of experts from SLAC and other DOE labs
Invited by LCLS Director
