Acceptance Criteria

• Oscillating collimator on LET should run

Shows two runs I wonder whether it is homing correctly.

Final thought I think the only place it can get stick is here:

1. OSCIL

2. 'Step 4 - Oscillations****
3. time1=TIME
4. SP~a=vel
5. PA~a=dist/2;BG~a;

6. CHECK1

7. JP #CHECK1, @IN[7]=0
8. check=_RP~a
9. AM~a
10. PA~a=-dist/2;BG~a;AM~a
11. count=count+1
12. time=TIME-time1
13. 'JP #HOMER, check>125
14. JP#OSCIL
15. EN

Is lines 6/7 which would happen if the home switch is never triggered (assume this is a trigger). Maybe we are not homing > correctly so the home switch is not in the collimator swing. But that is only a thought.

Motor was ~warn~ worn. Hardware to look at it

I've been watching the information flowing through exp controls for this, and the work no longer needs any support from us.
