Continue running polarized Deuterium. Injection current is 155 mA.
Genya suggests to measure (normalized) unpolarized elastic ep cross
section, once with regular setup and once with a minimal setup (i.e. only
two TOF paddles turned on) in order to clarify a miracle about count
rates, i.e. to exclude any problem introduced by the trigger hardware.
This is doable within less than a shift. Genya also reports a difference
in ed count rate on the order of 50% in his analysis compared to the one
of Chi.
We will have a meeting upon this issue some time next week, AFTER Genya
and Chi will have clarified their ed rates among each other.
Genya and Chi should do this as soon as possible.
Regards,
Michael
