Neutrino Factory Studies
ORNL completed two studies describing support facilities for neutrino factories
2000, Graphite Target
2019, Mercury Jet Target
Included descriptions of targets, expected radiation, required shielding, remote handling systems, and rough cost estimates
ORNL documents used as contributions to broader scope NFMCC documents
High Power Targets
Study 1 - Carbon Target
16 GeV, MW proton beam
cm diameter, 80 cm long graphite rod inside a helium environment
Target held by two spoke-like graphite supports
15 cm diameter containment tube
20 T magnetic field
High Power Targets
Study 2 – Mercury Jet Target
24 GeV, 1 MW proton beam
1 cm diameter, 30 m/s jet
20 T magnetic field
Removable nozzle assembly inside an iron core
High Power Targets
Study 2 Target-Capture Facility
24 GeV, 1 MW proton beam on Hg target
Upgradeable to 4 MW
20 T target solenoids
T capture solenoids
5-m steel shield for unlimited personnel access
Facility concept development
Beam, target parameters
Neutronic analysis
Shielding requirements
Equipment definition
RH requirements, crane sizing
Cost estimate
High Power Targets
The Target/Capture Facility is 40-m Long
Removable, stacked shielding allows personnel in the crane hall
50-ton crane and bridge manipulator are the primary remote handling tools
Shield
CRANE HALL
50 Ton
High Power Targets
Hg-Jet Target/Beam Absorber is a Closed Loop System
Hg jet interaction region: r = 5 mm x 30 cm long
110 liters of Hg total volume
V = 30 meters/s
Q = liters/s
High Power Targets
Hg-Target Hot Cell
All components can be remotely replaced
High Power Targets
Maintenance requirements for the target system components
Most of the target system components are life-of-the-facility
Key components are replaced every
