3CLAS12 Requirements
The 12 GeV physics program requires measurement
of exclusive reactions. At high energies cross
sections are small and high energy particles are
produced in the forward direction. The physics
program requires
- High operating luminosity of 1035 cm-2sec-1
- Small angle capabilities for charged and neutral
particle detection - Particle ID to higher momentum (e-/p-, p/K/p,
g/po) - More complete detection of hadronic final state

20Construction Hall B Risk Management
Risk Assessment Matrix
The Overall risk of the Hall B subsystems 1.4.2.3
1.4.2.6 is LOW JLab Staff experienced with
similar detector design and construction during
the original construction of Hall-B Moderate
risk for one detector element (SVT) and two
magnets Lack of in-house experience with SVT
detector technology Low likelihood but high
impact on technical and cost performance of
CLAS12 magnets
21Hall B Risk Management
- Silicon Vertex Tracker (SVT) considered
moderate risk due to limited expertise at JLab
with this technology. - Mitigation
- Attracted SiLab Group at Moscow State University
as collaborating member with broad expertise in
Silicon Detector Technology (D0, ZEUS, PHENIX,
TESLA) - Close monitoring and coordination of vendor
- Bi-weekly phone conferences of technical teams
- Mutual visits
- Documentation Technical Design Report
- Hall B Instrumentation Group developed in-house
expertise in SVT readout electronics and
interface with CODA

25Recommendation Tracker
- 05 IPR-24IPR Sec 2.5 (Detector)
- Advance the conceptual design of the CLAS12 SVT
and provide more engineering details. - Conceptual design has been significantly
advanced. Many more engineering details are
known for the design. - 05 IPR-25IPR Sec 2.5 (Detector)
- Study the CLAS 12 SVT conceptual design via
simulation. - Conceptual design has been refined as a
result of simulation studies. Reference for
these studies is CLAS-NOTE-2006-020. - 06 IPR -09 Detector
- Conduct external peer reviews of Hall B and
D detector designs and of superconducting magnet
designs in time to impact the baseline designs of
these subsystems. - An external peer review of the Hall B (and
C) superconducting magnets took place in
September 2006. An external peer review of the
Hall D and Hall B drift chambers in March 2007.
In April 2007, the Hall B preshower calorimeter
and high threshold Cerenkov Counter were reviewed
by an external panel. Review committee reports
from all of the above are included in the
pre-brief material.
26Recommendation Tracker
- 06 IPR -08Detector
- Continue development of full detector
simulation and reconstruction studies with the
goal of validating that detector designs meet
physics performance requirements for Halls B and
D. - In Hall B a focus group has developed a
GEANT simulation including all CLAS12 detectors
and magnets. Reconstruction software had been
developed for nearly all detectors as of April
2007. This simulation and reconstruction effort
will continue throughout the lifetime of the
project, however excellent progress has been made
to verify that the design meets physics
performance parameters. - 07 IPR -18Detectors
- Advance the design of the Hall B SVT.
Complete choice of readout IC and engineering
design of module by CD-3. - Work in Progress Will be done prior to
CD-3 IPR. -
27Summary
- The technical scope of the Hall B upgrade with
CLAS12 is well matched to the performance
requirements - Major portions of the project scope are based on
existing technology - Overall technical risks are low
- Moderate risk for SVT due to the Lack of
in-house experience with SVT detector technology -
- Utilize many components of CLAS and the Hall B
infrastructure - A strong and growing collaboration
- Planning is sound and based on the broad
previous experience of the scientific and
technical teams of Hall B and the Collaboration - Basic design parameters are well understood
- PED effort is well advanced in all areas
- Experienced staff is in place with an excellent
track record on the construction, operation, and
incremental upgrades of the Hall B equipment -
