Commissioning of GRETINA at the BGS

Workshop April 2009

From the Richmond Workshop Report

• Optimizing GRETINA Science
• A workshop dedicated to planning the first rounds
  of operation
• October 14 - 15, 2007 at the University of
  Richmond
• A unanimous view of how best to proceed with the
  optimization and science planning of GRETINA
  after the end of the engineering runs in February
  2011 was agreed upon. This plan is outlined
  below
• (i) Commissioning runs at LBNL for a period of
  2-3 months. These runs with GRETINA coupled to
  the BGS would be coordinated by the GAC.
  Primarily they will serve as the major debugging
  phase for GRETINA under real battle conditions
  with the critical benefit that most of the
  experts who had built up the various systems
  would be available locally. These runs would
  also provide the opportunity to obtain important
  physics results on the spectroscopy of super
  heavy elements (SHE). Indeed SHE studies have
  featured heavily in all GRETINA and GRETA (and
  recent Long Range Plan) documents. These runs
  would be contingent on (a) a study of the
  n-damage rate for detectors in the BGS
  environment, and (b) that site preparation be
  completed on time. After these commissioning runs
  GRETINA would be ready for moving to another
  laboratory to begin official PAC-approved physics
  campaigns.

The view from the Advisory Committee

• GRETINA is scheduled for completion (CD4) in
  March 2011
• We are very keen to get the best physics as
  quickly as possible. This is crucial for both the
  community and the GRETA proposal.
• We recommend that
• A single collaboration should be formed to
  perform, analyse and publish these experiments.
  Rod and Teng-Lek should be co-spokespersons.
• The analysis and paper-writing should be purely
  collaborative. Thus no PIs for individual
  experiments, and all members have access to the
  data.
• The author list of papers resulting from these
  commissioning runs should be I-Y Lee first, then
  alphabetical. It should include people who have
  spent at least 2 years of their career on
  GRETINA, such as postdocs.
• Inter-lab issues, conflicts of interest etc.,
  that cannot reasonably be resolved by the
  collaboration should be brought to the GAC for
  resolution.

Thanks

• Many thanks to the organizers, Rod and Teng-Lek,
  for this meeting, and for being willing to act as
  co-spokespersons.
• We should also all express our gratitude to the
  BGS group for being willing to interrupt their
  research program and host GRETINA for these
  experiments.
