keyword=Beam: 3C19 harp

I don't think the harp traces at 1H04 in hall A are directly relevant to Qweak.

The hall C harps after the Compton are 3C20, 3H07 A/B and 3H09 A/B. The 3H harps are after the fast raster and must be scanned with CW beam. Ion chambers will have to be masked. If you can convince the Crew Chief to allow masking of all but the dump ion chambers before taking a trace it will save time. Otherwise you'll have to watch Ops take repeated traces and trip successive ion chambers until most if not all but the dump chambers are masked.
