3:30PM Run Meeting, Counting house meeting room (200C)

RC: Cameron Clarke

Status

Control access to fix LHRS Dipole Quench

  • After recovering from a spontaneous (no clear cause) RQ2 quench, 2.5 hours later we got another spontaneous L Dipole quench
  • The hall will go into controlled access and Jack will diagnose the LHRS Dipole in the morning when he arrives
  • After recovering the LHRS Dipole we will return to 50uA running, depending on the status of PQB studies during Monday Day shift

Experiment Updates

Plan for Monday

  • Attempt to bring the LHRS Dipole back online as fast as possible to take advantage of beautiful 50uA running
  • Continue production data on Tungsten 2.8% target at 50uA, and move higher if possible.
  • Possibly (though still under discussion) take data during Monday Beam Studies Day shift if it takes place. Parity Quality Beam studies would be performed during Day shift and should not affect heavily the quantity or quality of beam delivered to the tungsten foil target.
