keyword=Hall C charge asymmetry
The Hall C charge asymmetry has been pretty stable over the last 6 slugs
at about -170 ppm with the half wave plate out and about -20 ppm with the
HWP in.
The IA slope for the Hall C charge asymmmetry determined during the
injector studies referenced here is 250 ppm/V. The flipper script will
now use an IA voltage of 5.8 for the IHWP OUT slugs (starting next slug)
and 5.2 for IHWP IN, (starting next run.)
