But Seriously

• The magnets have been used successfully for
• GDH
• Hypernuclear Spectroscopy
• HAPPEX

And pentaquark

• Problems
• Cooling of the right septum was not as good as
  expected
• HAPPEX limited to lt 40 µ-amps (with LH2 target)

Upon disassembly debris was found in the cooling
circuit of the right septum. Explains the
apparent malfunction of the suspicious check
