Beam Troubleshooting

If there is no beam, check:

(1) Are the shutters open?

(2) Is there SPEAR current?

(3) Check beam tuning

In microXAS GUI, select "Scan Motor"

As your detector, select "I0"

As your motor, select "TUNE"

Enter scan range (relative): -1 to 1

Enter step size: 0.1

Hit "Scan"

Select the maximum using the cursor, and then hit "Move"

(4) Make sure the TABLE motor is in the correct position? i.e., Do a TABLE scan

For this, your need a clear path for the beam to I1 (so move the sample out of the way)

In microXAS GUI, select "Scan Motor"

As your detector, select "I0"

As your motor, select "TABLE"

Enter scan range (relative): -1 to 1

Enter step size: 0.1

Hit "Scan"

Select the maximum using the cursor, and then hit "Move"
