[Primexd] Talk at the collaboration meeting

[Alexander Somov]

Hi Liping and Eugene,

I used 24 PAC days on the slide.

This number does not take into account that we
ran at smaller energy. In general one has to consider
the FOM.

Another thing is that we took data using a smaller photon flux
so the effective data sample is smaller (the sample is a bit
larger than a half of the required)

--

If we run for 54 days during next year, we'll almost
complete He target (again the FOM has to be considered,
but we can ignore it at the moment . . . )


Cheers,
              Sasha

The "official" - accepted by the management - estimate of the time spent is available from the Hall D page:

https://www.jlab.org/Hall-D/runs.html

It adds to 24 PAC days.

Hi, Sasha,

Your slides look very good.

I just have one comment regarding to the PAC days accumulated for the He target in slide #3.  Considering a lower beam energy,  we accumulated about 50% data for the He target in 2019 based on our discussion in July.

Cheers,

Liping

Hi,

I put a draft of slides for the collaboration meeting to
https://halldweb.jlab.org/DocDB/0047/004724/001/primex_10_22_2020.pdf<https://urldefense.proofpoint.com/v2/url?u=https-3A__nam05.safelinks.protection.outlook.com_-3Furl-3Dhttps-253A-252F-252Fhalldweb.jlab.org-252FDocDB-252F0047-252F004724-252F001-252Fprimex-5F10-5F22-5F2020.pdf-26data-3D04-257C01-257Cganl-2540uncw.edu-257C765cbd2d29e14fea6a3208d876abbc77-257C2213678197534c75af2868a078871ebf-257C1-257C0-257C637389827265646770-257CUnknown-257CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0-253D-257C1000-26sdata-3D7pAc84MxM7OkSJoIrvoBg0j-252B4hkwazjFvH9lfVwxCVQ-253D-26reserved-3D0&d=DwMFAg&c=CJqEzB1piLOyyvZjb8YUQw&r=lU05Rh9aCuulfMNDTEUwlg&m=cSdpDeAh6PNzfCE12qIosWdToOG0LMFhSPg4wOepJ1w&s=V2P-a1v_HgqA2DhxsUo-akNWWxWO3AwpU93B-Yy2YcE&e=>

Please take a look (I am still working on them)
