• simg2o4.001 - .003
• simg2o4.004 aborted for Paul to optimize beamline

Paul realigned beamline, increasing flux by at least an order of magnitude.

There is a small energy shift in the data of -0.415 eV, found by comparing simg2o4.003 and .006

All data from simg2o4.006 to the end of the experiment is shifted by -0.415 volts relative to earlier data

Time: 1520

• simg2o4.006 after realignment
• simg2o4.007 aborted

Time: 1640

• sio2.001 - .004 OK
• sio2.005 - .008 during fill
• sio2.009 - .010 OK
• sio2.011 aborted

Time: 2100

• sife.001 - .005

Time: 2345

• sife2o4.001 - .010, .017
