Where do we start we SHMS?

--> we start at 33 deg (SHMS is at 32.975 deg) and -1.7 GeV/c (negative polarity)

--> here we take data on LH2, LD2 and Al

Where do we go next with SHMS?

--> we change polarity to + and start the CSB measurements (highest to lowest angle, no need to cycle magnets)

Where do we start with HMS?

--> we start at 59 deg (HMS is at 58.98 deg) and +1.2 GeV/c (CSB measurements)

--> we have some LH2 running at +1.2 GeV/c and then we can go to the last momentum setting at this angle: +1.05 GeV/c; this will complete the F2 physics running with HMS

Where do we go next with HMS?

--> change polarity to negative and take a Cherenkov eff./calibration run and then do boiling studies (it should not impede the SHMS running though)

Simona's checklist before running

--> check SHMS and HMS angles (again), set SHMS to -1.7 and HMS to +1.2 GeV/c

--> trigger types should be: ELREAL for SHMS and ELCLEAN for HMS

--> check the E.D.T. setup for SHMS and HMS (should correspond to ELREAL and ELCLEAN, respectively)

--> check PID trigger legs thresholds

--> check hodoscope thresholds

--> set EDTM rate to 3 Hz (need to see the physics rates again)

--> When beam comes:

   --> beam spot on the YAG without raster 
   --> turn raster on
   --> C hole run with SHMS
