Instrumentation for Reactions and Astrophysics

• Orruba in Gammasphere
• Active Target arrays ANASEN AT-TPC
• Gas-filled spectrograph
• Transfer-reactions need recoil separator to
  establish subsequent particle-decay
• Low-energy n-detector for (d,n)

2
ORRUBAGS

• System for study of transfer reactionswith
  CARIBUbeams
• (d,p) as probeof shell structuren-rich nuclei
• Investigate (d,pg) as surrogate for (n,g)

3
Recoil detector

• Many astrophysicalexperiments want to use
  (d,n)and (d,p), (3He,d)transfer reactions
• Detect small decay branches p vs g and p vs
  alpha
• Can be replaced by
• heavy recoil detection, particle id
• RF-sweeper for HELIOS gt reduce beam contam.

LE Neutron-Detector

• Inverse Kinematics (d,n) reactionslow-energy
  (E100-300 keV) neutron detector needed(plastic
  or 6Li-based)
